FOR MECHANICAL ENGINEERING, FOOD, TEXTILE AND PHARMACEUTICAL INDUSTRIES.

For over 20 years, we have been making resin floors for industries according to the very highest quality standards. Industrial floors in self-levelling, epoxy or polyurethane resin are not only resistant to the effects of time and contact with abrasive liquids, fats, oils and chemicals. These surfaces also provide protection from mould and bacteria, and provide better hygiene than materials like concrete and ceramic tiles. For this reason our company also installs resin floors and surfaces in hospitals, clinics and environments where cleanliness is crucial.

THE ADVANTAGES OF RESIN INDUSTRIAL FLOORS

Resin industrial floors, made using top-quality Mapei products, are dustproof, waterproof and non-slip. They also adhere perfectly to surfaces, are resistant to chemical products and are easy to sanitize. Self-levelling resin is the ideal material for industries because it permits creating continuous surfaces on floors and walls, and is easy to clean and dry. It can also cover existing surfaces (concrete, tiles or clinker) and can be personalized with logos and coloured signs to indicate escape routes in case of fire, as required by Legislative Decree no. 81/2008.
In the industrial field, Vissa resin floors can be used for conductive, antistatic and standard finishes. These features make our floors particularly safe for any type of industry and manufacturing facility.

• alkalis, including sodium hydroxide at a concentration of 50%, and detergents normally used for cleaning floors up to a concentration of 20-30%, as long as they do not contain abrasive granules;
• sugars, including when in frequent contact with the floor;
• mineral oils, diesel, kerosene and petrol.
Floors coated with MAPEFLOOR SYSTEM 31 are not suitable for constant exposure to high temperatures and thermal shock.
COLOURS AVAILABLE
MAPEFLOOR SYSTEM 31 is available in 19 colours from the RAL colour chart: refer to the colours in the MAPECOLOR PASTE range for MAPEFLOOR I 300 SL.

YIELD
The consumption levels indicated below are for a cycle applied at a temperature of +15°C to +25°C on a smooth, compact concrete surface broadcast with quartz sand and prepared with a diamond grinding wheel or by light shotblasting. Rougher surfaces, or application at lower temperatures, will lead to an increase in consumption and longer hardening times.

PREPARATION OF THE SURFACE
1. Characteristics of the substrate Before applying the MAPEFLOOR SYSTEM 31 cycle, the substrate on which the coating is to be applied must be carefully analysed. The concrete screed for the substrate must be sound, compact, strong and clean and must be dimensioned according to the static and dynamic loads to which it will be subjected when in service. The flatness must be defined according to the final use. To get the best results, the following  must be checked:
• There must be no materials or debris on the substrate which could potentially impede adhesion of the coating, such as:
– cement laitance;
– dust or detached or loose material;
– protective wax, curing products, paraffin or efflorescence;
– oil stains or layers of dirty resin;
– traces of paint or chemical products.
Any other kind of material or substance that could affect adhesion of the coating must be removed before starting work. If such materials or substances are present, the substrate must be prepared by carrying out a specific preparation cycle. Please contact Mapei Technical Services Department for advice and information.
• The pull-off strength of the substrate must be more than 1.5 MPa.
• The level of moisture in the substrate must be a maximum of 4% and there must be a suitable vapour barrier or no capillary rising damp (check by testing with a sheet of polythene according to ASTM standards). If these conditions are not met, use MAPEFLOOR SYSTEM 51 or MAPEFLOOR SYSTEM 52, otherwise MAPEFLOOR SYSTEM 31 could detach and/or blisters could form in the coating. If all the above conditions are met, MAPEFLOOR SYSTEM 31 may be applied on concrete industrial floors, conventional or polymer-modified cementitious screeds and shrinkage-compensated screeds such as those made from MAPECEM or TOPCEM.
2. Preparation of the substrate
It is very important that the surface is prepared as specified to guarantee correct application and the best performance of the MAPEFLOOR SYSTEM 31 epoxy cycle. The most suitable method to prepare the surface is a diamond grinding wheel followed by removal of all the dust with a vacuum cleaner or by shotblasting, taking care not to go too deep into the substrate. Do not use chemical preparation methods, such as acid rinsing, or aggressive percussion tools, to prevent damaging the substrate. Any defects present, such as holes, pitting, cracking, etc., must be repaired beforehand using either EPORIP, PRIMER SN or MAPEFLOOR I 300 SL, depending on the width and depth of the defects and cracks. If the substrate needs to be consolidated use PRIMER MF or PRIMER EP (choose the most suitable product according to the porosity of the substrate, which will also have an effect on the consumption rate). If there are deep hollows or highly deteriorated areas on the substrate, repair these areas beforehand using MAPEFLOOR EP19 three-component epoxy mortar or with products from the MAPEGROUT range, which may also be used to integrate damaged joints. If any of the above conditions are not strictly adhered to, the quality of the coating may be poor.
3. Preliminary checks before application
Make sure that all the checks indicated in point
1 “Characteristics of the substrate” have been carried out, and that all the operations indicated in point  2 “Substrate preparation” have been carried out correctly. The surrounding temperature must be higher than +8°C (the ideal application temperature is +15°C to +25°C) and the temperature of the substrate must at least  3°C higher than the dewpoint temperature. 4. Preparation and application of the products Carefully follow the preparation instructions contained in the Technical Data Sheet for each single product used to form the complete system: PRIMER SN and MAPEFLOOR I 300 SL. Non-slip multi-layered coating - 0.8-1.2 mm
• 1° layer (PRIMER SN) Pour component B (4 kg) into component A (16 kg), add MAPECOLOR PASTE and mix with a drill at low speed with a spiral mixing attachment to form a smooth, even paste. While mixing, add 4 kg of QUARTZ 0.5 to the mixture prepared as described above, and continue mixing for a few minutes to form a smooth, even paste. Pour the product onto the floor to be coated and spread it out evenly and uniformly using a straight steel trowel. Fully broadcast the product while it is still wet with QUARTZ 0.5. For particular requirements, such as if a higher degree of non-slip finish is required, use quartz sand with a particle size of 0.3-0.9 mm or even larger. In such cases the consumption rate of the next coat will be higher. Once PRIMER SN has hardened remove all excess sand with an industrial vacuum cleaner, sand the surface and remove all traces of dust with a vacuum cleaner.
• Finishing coat (MAPEFLOOR I 300 SL) Pour component B (2 kg) into component A (6 kg), add MAPECOLOR PASTE (0.7 kg of MAPEFLOOR PASTE for each kit of MAPEFLOOR I 300 SL) and mix with a drill at low speed with a spiral mixing attachment to form a smooth, even paste. While mixing, add 0.5 kg of QUARTZ 0.25 to the mixture prepared as described above and mix again to form a smooth, even compound. Apply the compound with a medium-piled roller to form an even, seamless coat, making sure that the roller strokes criss-cross over each other to obtain a defect-free surface. An alternative method is to apply the compound with a straight steel trowel, spread it down to a feather edge and then backroll with a short-piled roller.
5. Hardening and step-on times
At +25°C MAPEFLOOR SYSTEM 31 sets to foot traffic after 16 hours, may be used by light loads after 1 to 2 days and is ready for final use once fully hardened after approximately 7 days. Lower temperatures lead to longer hardening and step-on times.
CLEANING AND MAINTENANCE
Regular cleaning and maintenance operations increase the life of a coated floor, improves its aesthetic properties and reduces its tendency to collect dirt. Floors created using the MAPEFLOOR SYSTEM are generally easy to wash with neutral detergents, or with alkali detergents diluted at a concentration of 5 to 10% in water. Special detergents and cleaning tools are readily available for cleaning resin floors. Manufacturers of these detergents supply all the information required for the cleaning procedures to apply. Our Technical Services Department is available for any information required.

NOTES
Recommendations regarding safe use and handling of the products are contained in the Material Safety Data Sheet for each single material in the cycle. However, the use of protective gloves and goggles is recommended when mixing and applying the products. If the cycle is applied on surfaces, in climatic conditions and/or for final uses not mentioned above, please contact the Technical Services Department at MAPEI S.p.A.

COLOURS AVAILABLE
MAPEFLOOR SYSTEM 32 is available in 19 different colours from the RAL range: refer to colours in the MAPECOLOR PASTE range for MAPEFLOOR I 300 SL.

YIELD
The consumption figures indicated below are based on application at a temperature between 15°C and 23°C on a smooth, compact concrete surface finished off with a diamond grinding disc or by light shot-blasting. Rougher surfaces or lower temperatures increase the consumption rate and lengthen the curing times. In particular, the consumption of PRIMER SN
may vary depending on substrate preparation.

SURFACE PREPARATION
1. Characteristics of the substrate
Before applying the MAPEFLOOR SYSTEM 32, an accurate, in-depth analysis of the substrate upon which the dressing is to be applied must be carried out. To make sure that a good result is obtained, verify the following:
• that the irregularity of the substrate does not exceed 0.5 mm;
• that there are no materials on the substrate which could impede the adhesion of successive finishes, such as:
– cement laitance;
– dust or areas which are either loose or not well bonded;
– protective wax, curing agents, paraffin or efflorescence;
– oil stains or layers of dirty resin;
– traces of paint or chemical products.
Other contaminants which may compromise bonding of the finish must be removed before carrying out installation. If the substrate is contaminated, it is ESSENTIAL to implement a suitable preparation technique. If necessary, contact our company’s Technical Services Department for advice.
• That the tear strength of the substrate is higher than 1.5 N/mm2.
• That the level of humidity in the substrate is no higher than 4%, and that there is an adequate vapour barrier installed. If these conditions are not met, use MAPEFLOOR SYSTEM 51 or MAPEFLOOR SYSTEM 52. The use of MAPEFLOOR SYSTEM 32 could lead to detachment and/or the formation of blisters. If the aforementioned prerequisites are met, MAPEFLOOR SYSTEM 32 may be applied on concrete industrial floors, traditional cementitious
screeds or polymer modified screeds, on shrinkage-compensated screeds such as MAPECEM or TOPCEM screeds, on old cement terrazzo surfaces and ceramic floors if prepared correctly.
2. Preparation of the substrate
Correct preparation of the surface is essential to guarantee application success and to guarantee the best performance of MAPEFLOOR SYSTEM 32. The most suitable preparation method is by shot-blasting or, as an alternative, by grinding with a diamond disc followed by vacuuming off the resulting dust. We advise against using chemical-based treatments, such as acid rinsing, or aggressive pneumatic hammering, which may damage the substrate. Any defects present, such as holes, cavities, cracking, etc. must be repaired beforehand using either EPORIP, PRIMER SN or MAPEFLOOR I 300 SL, depending on the size and depth of the defect or damaged area. If the substrate needs to be consolidated, use PRIMER MF or PRIMER EP (the choice of product depends on the porosity of the substrate, which will also effect the consumption rate). Large hollows or highly deteriorated areas must be rebuilt beforehand using either MAPEFLOOR EP 19 three component epoxy mortar or one of the products from the MAPEGROUT range. Joints which are in a poor condition must be rebuilt using the above materials. If the above guidelines are not followed, there will be a detrimental effect on quality of the work carried out.
3. Preliminary checks before application
Make sure that all the checks in item 1 “Characteristics of the substrate” have been carried out, and that all the operations indicated in item 2 “Preparation of the substrate” have been carried out correctly. The air temperature must be higher than +8°C (the most suitable temperature being +15°C to +25°C) and  the temperature of the substrate must be at least +3°C higher than the dew-point temperature.
4. Mixing and application
Follow the preparation instructions contained in the technical data sheet for each single component of the system; PRIMER SN and MAPEFLOOR I 300 SL. 3.0-3.5 mm-thick multi-layer non-slip dressing
• Primer (PRIMER SN)
Pour component B (4 kg) into component A (16 kg) and mix with a low-speed drill fitted with a spiral mixing attachment until a homogenous mix is obtained. Whilst mixing, add 4 kg of 0.5 QUARTZ to the blend, and continue to mix for a few minutes until homogenous. Pour the mix onto the floor and spread it out evenly and uniformly using a smooth spreader or a smooth rake. Whilst the product is still fresh, sprinkle on a layer of 0.5 QUARTZ.
• Vacuuming off the dust
When the PRIMER SN has cured, remove the excess sand with a heavy-duty vacuum cleaner.
• Intermediate layer (MAPEFLOOR I 300 SL) Pour component B (2 kg) into component A (6 kg), add the MAPECOLOR PASTE (0.7 kg of MAPECOLOR PASTE for each bag of MAPEFLOOR I 300 SL) and mix with a low-speed drill fitted with a spiral mixing attachment until a homogenous mix is obtained. Whilst mixing, add 3 kg of 0.5 QUARTZ to the blend, and continue to mix until homogenous. Pour the mix onto the previous layer, and spread it out evenly and uniformly using a smooth spreader or a smooth rake. Whilst the product is still fresh, sprinkle on a layer of 0.5 QUARTZ.
• Vacuuming off the dust
When the product has cured, the excess sand should be removed, and the surface vacuumed to remove excess dust.
• Finishing coat (MAPEFLOOR I 300 SL) Pour component B (2 kg) into component A (6 kg), add the colouring paste (MAPECOLOR PASTE) and mix with a low-speed drill fitted with a spiral mixing attachment until a homogenous mix is obtained. Whilst mixing, add 0.5 kg of 0.25 QUARTZ to the blend, and continue mixing until homogenous. Apply the mix uniformly and continuously using a medium-haired roller, making sure that the roll strokes criss-cross each other to obtain a defect-free surface.
5. Hardening and step-on times
At a temperature of 25°C, the MAPEFLOOR SYSTEM 32 finish may be stepped on after 16 hours. Trolleys and forklifts, however, may not drive on the surface for at least 24 hours. Lower temperatures lengthen the hardening and step-on times of the dressing.
CLEANING AND MAINTENANCE
Regular cleaning and maintenance increases the life of the treated floor, improves its appearance and reduces the floor’s tendency to attract dirt. Floors made using the MAPEFLOOR SYSTEM are generally easy to clean with neutral detergents or with alkalis diluted in water at a concentration from 5 to 10%. Also, detergents and cleaning equipment which are suitable for cleaning resin floors are widely available. Manufacturers of these products supply all the necessary information required regarding the correct procedures to adopt. The company’s Technical Services Department is also available
for any kind of clarification required.

NOTE
Information regarding safety equipment and handling of the products are contained in the technical data sheets for each single component of the system. However, we recommend that protective goggles and gloves are always used when mixing and applying the products. If the products are to be applied on surfaces or under climatic and/or service use conditions which are different from those indicated in the technical data sheet for the system, please contact MAPEI’s Technical Services Department.

YIELD
The consumption levels indicated below are for a cycle applied at a temperature of +15°C to +25°C on a smooth, compact concrete surface broadcast with quartz sand and prepared with a diamond grinding wheel or by light shotblasting. Rougher surfaces, or application at lower temperatures, will lead to an increase in consumption and longer hardening times. The consumption rate for PRIMER SN in particular may vary, depending on the type and depth of the method used to prepare the substrate.

SURFACE PREPARATION
1. Characteristics of the substrate Before applying the MAPEFLOOR SYSTEM 33 cycle, the substrate on which the coating is to be applied must be carefully analysed.
The concrete screed for the substrate must be sound, compact, strong and clean and must be dimensioned according to the static and dynamic loads to which it will be subjected when in service. The flatness must be defined according to the final use. To get the best results, the following must be checked:
• The roughness of the substrate must be a maximum of 0.5 mm.
• There must be no materials or debris on the substrate which could potentially impede adhesion of the coating, such as:
– cement laitance;
– dust or detached or loose material;
– protective wax, curing products, paraffin or efflorescence;
– oil stains or layers of dirty resin;
– traces of paint or chemical products.
Any other kind of material or substance that could affect adhesion of the coating must be removed before starting work. If such materials or substances are present, the substrate must be prepared by carrying out a specific preparation cycle. Please contact Mapei Technical Services Department for advice and information.
• The pull-off strength of the substrate must be more than 1.5 MPa.
• The level of moisture in the substrate must be a maximum of 4% and there must be a suitable vapour barrier or no capillary rising damp (check by testing with a sheet of polythene according to ASTM standards). If these conditions are not met, use
MAPEFLOOR SYSTEM 53, otherwise MAPEFLOOR SYSTEM 33 could detach and/or blisters could form in the coating. If all the above conditions are met, MAPEFLOOR SYSTEM 33 may be applied on concrete industrial floors, conventional or polymer-modified cementitious screeds, shrinkage-compensated screeds such as those made from MAPECEM or TOPCEM, old cement terrazzo floors and ceramic floors if prepared according to specification.
2. Substrate preparation
It is very important that the surface is prepared as specified to guarantee correct application and the best performance of the MAPEFLOOR SYSTEM 33 epoxy cycle. The most suitable method to prepare the surface is shot-blasting, or alternatively grinding with a diamond grinding wheel. All dust must then be removed with a vacuum cleaner. Do not use chemical preparation methods, such as acid rinsing, or aggressive percussion tools, to prevent damaging the substrate. Any defects present, such as holes, pitting, cracking, etc., must be repaired beforehand using either EPORIP, PRIMER SN or MAPEFLOOR I 300 SL, depending on the width and depth of the defects and cracks. If the substrate needs to be consolidated, use PRIMER MF or PRIMER EP (choose the most suitable product according to the porosity of the substrate, which will also have an effect on the consumption rate). If there are deep hollows or highly deteriorated areas on the substrate, repair these areas beforehand using MAPEFLOOR EP19 three-component epoxy mortar or with products from the MAPEGROUT line, which may also be used to integrate damaged joints. If any of the above conditions are not strictly adhered to, the quality of the coating may be poor.
3. Preliminary checks before application
Make sure that all the checks indicated in point 1 “Characteristics of the substrate” have been carried out, and that all the operations indicated in point 2 “Substrate preparation” have been carried out correctly. The surrounding temperature must be higher than +8°C (the ideal application temperature is +15°C to +25°C) and the temperature of the substrate must at least 3°C higher than the dew-point temperature.
4. Preparation and application of the products
Carefully follow the preparation instructions contained in the Technical Data Sheet for each single product used to form the complete system. PRIMER SN and MAPEFLOOR I 300 SL. Self-levelling coating - 2-4 mm
• Primer (PRIMER SN) Pour component B (4 kg) into component A (16 kg), add MAPECOLOR PASTE and mix with a drill at low speed with a spiral mixing attachment to form a smooth, even paste. While mixing, add 4 kg of QUARTZ 0.5 to the paste as soon as it has been prepared and continue mixing for several minutes to form a smooth, even compound. Pour the product onto the floor to be coated and spread it out evenly and uniformly using a straight trowel or a smooth spreader. Broadcast the product while it is still wet with QUARTZ 0.5 (approximately 1 kg/m²). If the surface is still porous, is not compact or if it has open micro-pores due to its high absorbency after the first coat of primer, apply a second smoothing layer of PRIMER SN as described above until all porosity has been completely eliminated. If the porosity is not correctly sealed, pinholes and defects could form in the finishing coat of MAPEFLOOR I 300 SL. Once the PRIMER SN has hardened, remove all excess sand with an industrial vacuum cleaner.
• Self-levelling coat (MAPEFLOOR I 300 SL) Pour component B (2 kg) into component A (6 kg), add MAPECOLOR PASTE (0.7 kg of MAPEFLOOR PASTE for each
kit of MAPEFLOOR I 300 SL) and mix with a drill at low speed with a spiral mixing attachment to form a smooth, even paste. While mixing, add 8 kg of QUARTZ 0.25 to the mixture prepared as described above and continue mixing for a few minutes to form a smooth, even compound. Pour MAPEFLOOR I 300 SL onto the floor to be coated and spread it out evenly and uniformly using a straight trowel or a notched spreader with “V”-shaped teeth. While the product is still wet, immediately pass over the surface with a spiked roller to help completely eliminate any air entrained into the product during mixing.
5. Hardening and step-on times
At +25°C MAPEFLOOR SYSTEM 33 sets to foot traffic after 16 hours, may be used by light loads after 1 to 2 days and is ready for final use once fully hardened after approximately 7 days. Lower temperatures lead to longer hardening and step-on times.
CLEANING AND MAINTENANCE
Regular cleaning and maintenance operations increase the life of a coated floor, improves its aesthetic properties and reduces its tendency to collect dirt. Floors created using the MAPEFLOOR SYSTEM are generally easy to clean with neutral detergents, or with alkali detergents diluted at a concentration of from 5 to 10% in water. MAPEFLOOR MAINTENANCE KIT is available for maintenance operations and includes MAPELUX LUCIDA metallic wax, MAPEFLOOR WAX REMOVER and MAPEFLOOR CLEANER ED detergent for daily cleaning operations. If MAPEFLOOR SYSTEM 33 is applied in civil environments, we recommend waxing the floor with
MAPELUX LUCIDA or MAPELUX OPACA special metallic wax. Our Technical Services Department is available for any information required.

• Quick, easy installation with reduced plant down times.
• Guarantees an excellent cost-performance ratio.

CHEMICAL RESISTANCE
Floors prepared with MAPEFLOOR SYSTEM 51 are resistant to:
• dilute mineral acids , such as: hydrochloric acid, nitric acid, phosphoric acid and sulphuric acid. Limited resistance to organic acids (refer to the chemical resistance table in the technical data sheet for MAPEFLOOR I 500 W);
• alkalis, including sodium hydroxide at 50% concentration, and detergents normally used for cleaning floors, up to a concentration of 20- 30%, as long as they do not contain abrasive material;
• sugary substances, even if in frequent contact.
COLOURS AVAILABLE
MAPEFLOOR SYSTEM 51 is available in 19 different colours from the RAL range: refer to colours in the MAPECOLOR PASTE range for MAPEFLOOR I 500 W.

YIELD
The consumption figures indicated below are based on application at a temperature between 15°C and 23°C on a smooth, compact concrete surface finished off by shot-blasting. Rougher surfaces or lower temperatures increase the consumption rate and lengthen the curing times. In particular, the consumption of the first layer may vary depending on substrate preparation.

SURFACE PREPARATION
1. Characteristics of the substrate
Before applying the MAPEFLOOR SYSTEM 51, an accurate, in-depth analysis of the substrate upon which the dressing is to be applied must be carried out. To make sure that a good result is obtained, verify the following:
• That the surface irregularity does not exceed 0.3 mm.
• That there are no materials on the substrate which could impede the adhesion of successive finishes, such as:
– cement laitance;
– dust or areas which are loose or not well bonded;
– protective wax, curing agents, paraffin or efflorescence;
– oil stains or layers of dirty resin;
– traces of paint or chemical products.
• Other contaminants which may compromise bonding of the dressing must be removed before carrying out installation. If the substrate is contaminated, it is ESSENTIAL to implement a suitable preparation technique. If necessary, contact our company’s Technical Services Department for advice.
• That the tear strength of the substrate is higher than 1.5 N/mm2.
• If the aforementioned prerequisites are met,
MAPEFLOOR SYSTEM 51 may be applied on concrete industrial floors, traditional cementitious screeds or polymer modified screeds or on shrinkage-compensated screeds such as MAPECEM or TOPCEM screeds.
2. Preparation of the substrate
Correct preparation of the surface is essential to guarantee successful application, and to guarantee the best performance of MAPEFLOOR SYSTEM 51.
The most suitable preparation method is by shotblasting, taking care to penetrate too deeply into the substrate. We advise against using chemicalbased treatments, such as acid rinsing, or aggressive pneumatic hammering, which may damage the substrate. Any defects present, such as holes, cavities, cracking, etc. must be repaired beforehand using either EPORIP, PRIMER SN or MAPEFLOOR I 500 W, depending on the size and depth of the defect or damaged area. If the substrate needs to be consolidated, use diluted MAPECOAT I 600 W (the dilution ratio depends on the porosity of the substrate, which will also effect the consumption rate). Large hollows or highly deteriorated areas must be rebuilt beforehand using either MAPEFLOOR EP 19 three-component epoxy mortar or one of the products from the MAPEGROUT range. Joints which are in a poor condition must be rebuilt using the above materials. If the above guidelines are not followed, there will be a detrimental effect on quality of the work carried out.
3. Preliminary checks before application
Make sure that all the checks in item 1 “Characteristics of the substrate” have been carried out, and that all the operations indicated in item 2 “Preparation of the substrate” have been carried out correctly. The air temperature must be higher than 8°C (the most suitable temperature being from 15°C to 25°C) and the temperature of the substrate must be at least 3°C higher than the dew-point temperature.
4. Mixing and application
Follow the instructions in the technical data sheet for each single component of the MAPEFLOOR I 500 W system. 3 mm-thick multi-layer non-slip finish Before application, wet the surface to be treated, taking care not to form puddles or to leave spanding water.
• Primer (MAPEFLOOR I 500 W)
Pour component A (2 kg) into component B (24 kg), add the colouring paste (MAPECOLOR PASTE) and mix with a lowspeed drill fitted with a spiral mixing attachment until a homogenous mix is obtained. Whilst mixing, slowly add 2 litres of water and continue mixing until a homogenous blend is obtained. Pour the mix onto the floor and spread it out evenly and uniformly using a smooth spreader or a serrated rake. Whilst the product is still fresh, sprinkle on a layer of 0.5 QUARTZ.
• Vacuuming off the dust
When the MAPEFLOOR I 500 W has cured, remove the excess sand and vacuum off the excess dust.
• Finishing coat (MAPEFLOOR I 500 W)
Pour component A (2 kg) into component B (24 kg), add the colouring paste (MAPECOLOR PASTE) and mix with a low-speed drill fitted with a spiral mixing attachment until a homogenous mix is obtained. Whilst mixing, slowly add 2 litres of water and continue mixing until homogenous. Pour the mix onto the floor and spread it evenly and uniformly using a smooth spreader or a smooth rake. If necessary, pass over the surface with a medium-haired roller to create a more uniform finish.
5. Hardening and step-on times
At a temperature of 25°C, MAPEFLOOR SYSTEM 51 may be stepped on after 16 hours. Trolleys and forklifts, however, may not drive on the surface for at least 24 hours. Lower temperatures and high relative humidity lengthen the hardening and step-on times of the dressing.
CLEANING AND MAINTENANCE
Regular cleaning and maintenance increases the life of the treated floor, improves its appearance and reduces the floor’s tendency to attract dirt. Floors made using the MAPEFLOOR SYSTEM are generally easy to clean with neutral detergents or with alkalis diluted in water at a concentration from 5 to 10%. Also, detergents and cleaning equipment which are suitable for cleaning resin floors are widely available. Manufacturers of these products supply all the necessary information required regarding the correct procedures to adopt. The company’s Technical Services Department is also available for any kind of clarification required.

NOTE
Information regarding safety equipment and handling of the products are contained in the technical data sheets for each component. However, we recommend that protective goggles and gloves are always used when mixing and applying the products.
If the products are to be applied on surfaces or under climatic and/or service conditions which are different from those indicated in the technical data sheet for the system, please contact MAPEI’s Technical Services Department.

At room temperature, floors coated with MAPEFLOOR SYSTEM 91 are resistant to:
• diluted mineral acids such as hydrochloric, nitric, phosphoric and sulphuric acids and limited resistance to organic acids (refer to the chemical resistance table in the MAPEFLOOR I 300 SL Technical Data Sheet);
• alkalis, including sodium hydroxide at a concentration of 50%, and detergents normally used for cleaning floors up to a concentration of 20-30%, as long as they do not contain abrasive granules;
• sugars, including when in frequent contact with the floor;
• mineral oils, diesel, kerosene and petrol. Floors coated with MAPEFLOOR SYSTEM 91 are not suitable for constant exposure to high temperatures.

COLOURS AVAILABLE
MAPEFLOOR SYSTEM 91 is available in 19 colours from the RAL colour chart: refer to the colours in the MAPECOLOR PASTE range for MAPEFLOOR I 300 SL.

YIELD
The consumption levels indicated below are for a cycle applied at a temperature of +15°C to +25°C on a smooth, compact concrete surface finished with dry shake hardener and prepared with a diamond grinding wheel or by light shot-blasting. Rougher surfaces, or application at lower temperatures, will lead to an increase in consumption and longer hardening times. The consumption of PRIMER SN in particular may vary according to the type and depth of the preparation cycle carried out on the substrate.
1. Characteristics of the substrate Before applying the MAPEFLOOR SYSTEM 91 cycle, the substrate on which the coating is to be applied must be carefully analysed. The concrete screed for the substrate must be sound, compact, strong and clean and must be dimensioned according to the static and dynamic loads to which it will be subjected when in service. The flatness must be defined according to the final use. To get the best results, the following must be checked:
• The roughness of the substrate must be a maximum of 2 mm.
• There must be no materials or debris on the substrate which could potentially impede adhesion of the coating, such as:
– cement laitance;
– dust or detached or loose material;
– protective wax, curing products, paraffin or efflorescence;
– oil stains or layers of dirty resin;
– traces of paint or chemical products.
• Any other kind of material or substance that could affect adhesion of the coating must be removed before starting work. If such materials or substances are present, the substrate must be prepared by carrying out a specific preparation cycle. Please contact Mapei Technical Services Department for advice and information.
• The pull-off strength of the substrate must be more than 1.5 MPa.
• The level of moisture in the substrate must be a maximum of 4% and there must be a suitable vapour barrier or no capillary rising damp (check by testing it with a sheet of polythene according to ASTM standards). If these conditions are not met, use MAPEFLOOR SYSTEM 51 or MAPEFLOOR SYSTEM 52.
• If all the above conditions are met, MAPEFLOOR SYSTEM 91 may be applied on concrete industrial floors, conventional or polymer-modified cementitious screeds, shrinkage-compensated screeds such as those made from MAPECEM or TOPCEM, old cement terrazzo floors and ceramic floors if prepared according to specification.
2. Preparation of the substrate
It is very important that the surface is prepared as specified to guarantee correct application and the best performance of the MAPEFLOOR SYSTEM 91 epoxy cycle. The most suitable method to prepare the surface is milling or, as an alternative, shot-blasting. All dust must then be removed with a vacuum cleaner. Do not use chemical preparation methods, such as acid rinsing. Any defects present, such as holes, pitting, cracking, etc. must be repaired beforehand using either EPORIP, PRIMER SN or MAPEFLOOR I 900 fillerized with QUARTZ 0.5, depending on the width and depth of the defects and cracks. If the substrate needs to be consolidated, use PRIMER MF or PRIMER EP (choose the most suitable product according to the porosity of the substrate, which will also have an effect on the consumption rate). If there are deep hollows or badly deteriorated areas on the substrate, repair these areas beforehand using MAPEFLOOR I 900 fillerized with QUARTZ 1.9 or with products from the MAPEGROUT range, which may also be used to integrate damaged joints. If any of the above conditions are not strictly adhered to, the quality of the coating may be poor.
3. Preliminary checks before application
Make sure that all the checks indicated in point 1 “Characteristics of the substrate” have been carried out, and that all the operations indicated in point 2 “Preparation of the substrate” have been carried out correctly. The surrounding temperature must be higher than +8°C (the ideal application temperature is +15°C to +25°C) and the temperature of the substrate must at least 3°C higher than the dew-point temperature.
4. Preparation and application of the products
Carefully follow the preparation instructions contained in the Technical Data Sheet for each single product used to form the complete system: MAPEFLOOR I 900 and MAPEFLOOR I 300 SL. Non-slip mortar coating - 6 to 15 mm • Adhesion promoter (PRIMER SN) Pour component B (4 kg) into component A (16 kg) and mix with a drill with a spiral mixing attachment to form a smooth, even paste. Spread the product on the surface using a medium-piled roller. Apply the next layer of mortar on the primer while it is still wet.
• Preparing and spreading the mortar
(MAPEFLOOR I 900) Put 180 kg of QUARTZ 1.9 into a horizontal cement mixer and prepare the MAPEFLOOR I 900 seperately, by pouring component B (5 kg)
into component A (10 kg) and mixing with a drill with a spiral mixing attachment to form a smooth, even paste. Switch on the cement mixer and pour the mix in a slow, continuous flow into the mixer with QUARTZ 1.9 and keep mixing to form a mix with a screed mortar consistency. Pour the mix onto the adhesion promoter while it is still wet using rakes, spacers and an alluminium straight edge. The spacers should consider the next compacting and smoothing operations to bring the mortar down to the final thickness required.
• Compacting and smoothing the mortar Smooth over the surface of the mortar with a mechanical float (power floater) while the mortar is still wet.
• First smoothing coat for the mortar (MAPEFLOOR I 300 SL) Pour component B (2 kg) into component A (6 kg), add MAPECOLOR PASTE (0.7 kg of MAPEFLOOR PASTE for each kit of MAPEFLOOR I 300 SL) and mix with a drill at low speed with a spiral mixing attachment to form a smooth, even paste. While mixing, add approximately 1.8 kg of QUARTZ 0.25 to the paste as soon as it has been prepared and mix again to form a smooth, even compound. The amount of QUARTZ 0.25 may vary if necessary, depending on the porosity of the mortar. Pour the product on the previous coat and spread it out evenly and uniformly down to a feather edge using a straight trowel or a straight spreader.
• Cutting and sealing expansion joints (MAPEFLOOR PU45) Cut contraction and expansion joints with a clipper following the same layout as the existing ones. Then seal the joints with MAPEFLEX PU45. For static joints, or joints with very low expansions the sealing with MAPEFLEX PU45 is also possible. If an anti-slip finish is required, broadcast the wet surface with QUARTZ 0.5 or QUARTZ 0.9.
• Second smoothing coat for the mortar (MAPEFLOOR I 300 SL) When the previous layer has hardened, and always within 12 hours of application, pour component B (2 kg) into component A (6 kg), add MAPECOLOR PASTE (0.7 kg for each kit of MAPEFLOOR I 300 SL) and mix with a drill at low speed with a spiral mixing attachment to form a smooth, even paste. While mixing, add approximately 4.8 kg of QUARTZ 0.25 to the paste as soon as it has been prepared and mix again to form a smooth, even  ompound. Pour the product on the previous coat and spread it out evenly and uniformly down to a feather edge using a straight trowel or a straight spreader.
• Finishing coat (MAPEFLOOR I 300 SL) Pour component B (2 kg) into component A (6 kg), add MAPECOLOR PASTE and mix with a drill at low speed with a spiral mixing attachment to form a smooth, even paste. While mixing, add 0.8 kg of QUARTZ 0.5 to the paste as soon as it has been prepared and mix again to form a smooth, even paste. Apply the paste with a medium-piled roller to form an even, seamless coat, making sure that the roller strokes criss-cross over each other to obtain a
defect-free surface.
5. Hardening and step-on times
At +25°C MAPEFLOOR SYSTEM 91 sets to foot traffic after 16 hours, may be used by light loads after 1 to 2 days and is ready for final use once fully hardened after approximately 7 days. Lower temperatures lead to longer hardening and stepon times.
CLEANING AND MAINTENANCE
 Regular cleaning and maintenance operations increase the life of a coated floor, improves its aesthetic properties and reduces its tendency to collect dirt. Floors created using the MAPEFLOOR SYSTEM are generally easy to clean with neutral detergents, or with alkali detergents diluted at a concentration of from 5 to 10% in water. Special detergents and cleaning tools are readily available for cleaning resin floors. Manufacturers of these detergents supply all the information required for the cleaning procedures to apply. Our Technical Services Department is available for any information required.

NOTES
Recommendations regarding safe use and handling of the products are contained in the Material Safety Data Sheet for each single material in the cycle. However, the use of protective gloves and goggles is recommended when mixing and applying the products. If the cycle is applied on surfaces, in climatic conditions and/or for final uses not mentioned above, please contact the Technical Services Department at MAPEI S.p.A.
 

Mapefloor CPU/HD

Mapefloor CPU/HD is a three-component polyurethane/ cement-based formulate used to create protective coatings on industrial floors subjected to heavy traffic, high chemical aggression, thermal shock, etc. Some application examples
• Coating floors in the chemical and pharmaceutical industries.
• Coating floors in the foodstuffs industry.
• Coating floors in the dairy products industry.
• Coating floors in wineries, breweries and beverage industry in general.

[read more]


TECHNICAL CHARACTERISTICS
Mapefloor CPU/HD is a formulate made from cement, selected aggregates and polyurethane resin according to a formula developed in the MAPEI research laboratories. Mapefloor CPU/HD is used to create seamless coatings from 6 to 9 mm thick characterised by high resistance to chemicals such as acids, basic solutions, grease, saline solutions, hydrocarbons, etc. A 9 mm thick coat of Mapefloor CPU/HD has excellent resistance to thermal shocks of up to +120°C, such as when steam cleaning is carried out. The in-service temperature for a 9 mm thick coating of Mapefloor CPU/HD varies from -40°C to +120°C in dry environments and up to +100°C in wet environments. Thanks to its high mechanical strength and resistance to abrasion, Mapefloor CPU/HD is suitable for floors subjected to heavy traffic. Coatings made from Mapefloor CPU/HD are easy to clean and have a rough, non-slip finish.

COLOURS AVAILABLE
Mapefloor CPU/HD is a neutral-grey colour and must be coloured on site at the moment it is applied by adding Mapecolor CPU which is available in grey, beige, oxide red, green and ochre yellow.

RECOMMENDATIONS
• Do not apply Mapefloor CPU/HD on substrates with a film of surface water or on concrete within 10 days of pouring.
• Do not dilute Mapefloor CPU/HD with solvent or water.
• Do not apply Mapefloor CPU/HD on dusty or crumbling substrates.
• Do not apply Mapefloor CPU/HD on substrates with oil or grease stains or stains in general.
• Do not apply Mapefloor CPU/HD on substrates that have not been prepared according to specification.
• Do not mix partial quantities of the components to avoid mixing errors; the product may not harden correctly.
• Do not expose the mixed product to sources of heat.
• Do not apply Mapefloor CPU/HD on ceramic substrates or stone in general.
• Mapefloor CPU/HD coatings change colour if exposed to sunlight but this has absolutely no effect on their performance characteristics.
• The coating may also change colour if it comes into contact with aggressive chemicals. A change in colour, however, does not mean that it has been damaged by the chemical.
• Remove aggressive chemicals as soon as possible if they come into contact with Mapefloor CPU/HD.  
Use suitable specific cleaning equipment and detergent to clean the coating, depending on the type of dirt or stain to be removed.
• Protect coatings from water for at least 24 hours after application.
• The temperature of the substrate must be at least 3°C higher than the dew-point temperature.

APPLICATION TECHNIQUE
Preparation of the product The surface of concrete floors must be dry or slightly damp, clean and sound and have no crumbling or detached portions. Concrete must have been poured at least 10 days before applying the coating, its compressive strength must be at least 25 N/mm2 and its tensile strength must be at least 1.5 N/mm2. The strength of the substrate must also be suitable for its final use and the types of load to which it will be subjected. The surface of the floor must be prepared with a suitable process (e.g. shot-blasting or grinding) to remove all traces of dirt and cement laitance and crumbling or detached portions, and to make the surface rough and absorbent. Before applying the coating, remove all dust from the surface with a vacuum cleaner.
Repair cracks by filling them with Eporip and repair areas of the concrete in poor condition with Mapefloor CPU/HD, Mapefloor EP19 or with a cementitious mortar from the Mapegrout range. Before applying Mapefloor CPU/HD remove all traces of dust from the surface with a vacuum cleaner. Create anchoring grooves around the edge of the area to be coated and in proximity to all vertical elements such as walls, pillars, cable troughs, drains, etc. Grooves must also be created if application of the coating is interrupted, such as alongside joints when work finishes for the day or when starting work again. The width and depth of the grooves must be around twice the thickness of the Mapefloor CPU/HD coating to be applied. Application of primer Primer is not generally required.
However, on particularly porous substrates where pin-holes are more likely to form as the product hardens, we recommend skimming the surface with a thin coat of Primer SN followed by a full broadcast of 0.9 mm quartz sand on the surface to saturate the porosity of the substrate. Please refer to the Primer SN Technical Data Sheet for further information on its use and application.
Preparation of the product Pour component A into a large, clean container and, after mixing it, add component B and mix again with an electric mixer at low speed until it is completely blended. Then add component C and Mapecolor CPU powered colouring agent slowly and gradually (one 5 kg bag of Mapefloor CPU for every kit of Mapefloor CPU/HD A+B+C) and continue mixing until an even coloured mix is obtained. We recommend a specific low speed mortar mixer for this operation, such as a vertical mixer or a mixer with static blades and a rotating mixing drum. Apply the mix within the pot life indicated in the table (refers to a temperature of +20°C). Higher surrounding temperatures will reduce the pot life of the mix, while lower temperatures will increase its pot life. Application of the product
Pour Mapefloor CPU/HD onto the floor and spread it out evenly to the thickness required with a steel straight trowel or a notched float or a float with spacers. After spreading the coating, level and smooth off the surface with a long-bladed flooring trowel. If the surface of Mapefloor CPU/HD is worked too much it may cause the more fluid resinous part of the product to bleed through and make the coating less rough. We recommend applying the product so that each batch is applied immediately after the previous one while it is still wet and workable to reduce the number of joint marks.

CONSUMPTION
Mapefloor CPU/HD (A+B+C) + Mapecolor CPU Approx. 2.0 kg/m2 per mm of thickness. Consumption is influenced by the condition of the surface to be coated, its absorbency and roughness, site conditions, etc. Cleaning tools Clean tools used to prepare and apply Mapefloor CPU/HD with polyurethane thinners immediately after use. Once hardened, the product may only be removed using mechanical means.

HARDENING TIME
Floors coated with Mapefloor CPU/HD set to light foot traffic after approximately 8 hours at +20°C and may be opened to light vehicle traffic after approximately 24 hours at +20°C. The product develops its full strength after 4 to 5 days at minimum +20°C, although it depends on the actual surrounding conditions on site.

PACKAGING
Mapefloor CPU/HD: 25.8 kg units (component A = 2.6 kg + component B = 2.7 kg + component C = 20.5 kg). One 5 kg bag of Mapecolor CPU colouring powder must also be added to each 25.8 kg kit of Mapefloor CPU/HD, which brings the total weight of each batch to 30.8 kg.
STORAGE 12 months in a dry area in its original packaging at a temperature of between +5°C and +30°C. Mapefloor CPU/HD component C complies with the prescriptions of Reg. (EC) N. 1907/2006 (REACH) - Annex XVII, article 47.

SAFETY INSTRUCTIONS FOR PREPARATION AND APPLICATION

TECHNICAL CHARACTERISTICS
Mapefloor CPU/MF is a three-component formulate made from cement, selected aggregates and polyurethane resin according to a formula developed in the MAPEI research laboratories. Mapefloor CPU/MF complies with standards applied in the foodstuffs sector. EN 1186, EN 13130 and prCEN/TS 14234, as well as the Decree Of Consumer Goods that represent the conversion of European directive 89/109/EEC, 90/128/EEC and 2002/72/EC regarding contact with foodstuffs. Mapefloor CPU/MF is used to create seamless coatings from 3 to 6 mm thick characterized by high resistance to chemicals such as acids, basic solutions, grease, saline solutions, hydrocarbons, etc. A 6 mm thick coat of mapefloor CPU/MF has excellent resistance to thermal shocks of up to +70°C, such as when cleaning with hot water is carried out. The in-service temperature for a 6 mm thick coating of Mapefloor CPU/MFvaries from -40°C to +70°C. Thanks to its high mechanical strength and resistance to abrasion, Mapefloor CPU/MF is suitable for floors subjected to heavy traffic. Coatings made from Mapefloor CPU/MF are easy to clean and have a smooth finish or, if required, a rough, non-slip finish.

COLOURS AVAILABLE
Mapefloor CPU/MF is a neutral colour and must be colored on site at the moment it is applied by adding Mapecolor CPU which is available in grey, beige, oxide red, green and ochre yellow.

RECOMMENDATIONS
• Do not apply Mapefloor CPU/MF on substrates with a film of surface water or on concrete within 10 days of pouring.
• Do not dilute Mapefloor CPU/MF with solvent or water.
• Do not apply Mapefloor CPU/MF on dusty or crumbling substrates.
• Do not apply Mapefloor CPU/MF on substrates with oil or grease stains or stains in general.
• Do not apply Mapefloor CPU/MF on substrates that have not been prepared according to specification.
• Do not mix partial quantities of the components to avoid mixing errors; the product may not harden correctly.
• Do not expose the mixed product to sources of heat.
• Do not apply Mapefloor CPU/MF on ceramic substrates or stone materials in general.
• Mapefloor CPU/MF coatings change colour if exposed to sunlight but this has absolutely no effect on their performance characteristics thin layer of Mapefloor CPU/MFskimmed to a feather edge. The product must be completely hardened before applying the final coat of Mapefloor CPU/MF. Wait at least 12 hours at +20°C, depending on the actual site conditions; the scratch coat of Mapefloor CPU/MF must never be sticky. A coat of primer or skim coat is not required on substrates that are not particularly porous if the coat of Mapefloor CPU/MF is broadcast with quartz sand to obtain a non-slip finish.
Preparation of the product Pour component A into a large, clean container and, after mixing it, add component B and mix again with an electric mixer at low speed until it is completely blended.
Then add component C and Mapecolor CPUpowered colouring agent slowly and gradually (one 5 kg bag of Mapefloor CPU for every kit of Mapefloor CPU/MFA+B+C) and continue mixing until an even coloured mix is obtained. We recommend a specific low speed mortar mixer for this operation, such as a vertical mixer or a mixer with static blades and a rotating mixing drum. Apply the mix within the pot life indicated in the table (refers to a temperature of +20°C). Higher surrounding temperatures will reduce the pot life of the mix, while lower temperatures will increase its pot life. Application of the product Smooth self-levelling coating Pour  Mapefloor CPU/MF onto the floor and spread it out evenly to the thickness required, from 3 to 6 mm, with a smooth or notched trowel or a float with spacers. Immediately after applying Mapefloor CPU/MF, backroll intensively with a spiked-roller to remove entrapped air and reach an even surface.
Rough broadcast coating Pour Mapefloor CPU/MF onto the floor and spread it out evenly to the thickness required, from 3 to 6 mm, with a smooth or notched trowel or a float with spacers. Immediately after spreading Mapefloor CPU/MF, broadcast with Quartz 0.5 to obtain a rough surface finish. To obtain an even rougher finish with better non-slip properties, quartz sand with a larger particle size may be used. When the Mapefloor CPU/MF has completely hardened, remove the excess sand and saturate the surface by applying Mapefloor CPU/TC polyurethane/cement-based free-flowing coloured mortar with a roller or trowel. We recommend using Mapefloor CPU/TC in the same or a similar colour to the Mapefloor CPU/MF
undercoat to get the best cover and most regular, evenly coloured finish possible. We recommend applying the product so that each batch is applied immediately after the previous one while it is still wet and workable to reduce the number of joint marks.

CONSUMPTION
1. Smooth self-levelling coating - thickness 3-6 mm Primer: Primer SN (A+B + Quartz 0.5):0.7-0.8 kg/m²
• The coating may also change colour if it comes into contact with aggressive chemicals. A change in colour, however, does not mean that it has been damaged by the chemical.
• Remove aggressive chemicals as soon as possible if they come into contact with Mapefloor CPU/MF.
• Use suitable specific cleaning equipment and detergent to clean the coating, depending on the type of dirt or stain to be removed.
• Protect the coating from water for at least 24 hours after application.
• The temperature of the substrate must be at least 3°C higher than the dew-point temperature.

APPLICATION PROCEDURE
Preparation of the substrate The surface of concrete floors must be dry or slightly damp, clean and sound and have no crumbling or detached portions. Concrete must have been poured at least 10 days before applying the coating, its compressive strength must be at least 25 N/mm² and its tensile strength must be at least 1.5 N/mm². The strength of the substrate must also be suitable for its final use and the types of load to which it will be subjected. The surface of the floor must be prepared with a suitable process (e.g. shot-blasting or grinding) to remove all traces of dirt and cement laitance and crumbling or detached portions, and to make the surface rough and absorbent. Before applying the coating, remove all dust from the surface with a vacuum cleaner. Repair cracks by filling them with Eporip
and repair areas of the concrete in poor condition with Mapefloor CPU/MF, Mapefloor EP19 or with a cementitious mortar from the Mapegrout line.Before applying Mapefloor CPU/MF remove all traces of dust from the surface with a vacuum cleaner. Create anchoring grooves around the edge of the area to be coated and in proximity to all vertical elements such as walls, pillars, cable troughs, drains, etc. Grooves must also be created if application of the coating is interrupted, such as alongside joints when work finishes for the day or when starting work again. The width and depth of the grooves must be around twice the thickness of the Mapefloor CPU/MF coating to be applied. Application of primer Before applying Mapefloor CPU/MF, treat the surface with a coat of primer to saturate the porosity of the substrate. Use Primer SN mixed with 20-30% in weight of Quartz 0.5 for this operation. Pour the mixture on the surface of the clean, de-dusted floor and spread it to a feather edge with a smooth steel trowel. Immediately after applying the primer, broadcast with 0.3 mm-0.9 mm quartz sand. Wait until Primer SN has completely hardened before removing any excess sand and applying Mapefloor CPU/MF. Please refer to the Primer SN Technical Data Sheet for further information on its use and application. As an alternative to Primer SN, apply a thin layer of Mapefloor CPU/MF skimmed to a feather edge. The product must be completely hardened before applying the final coat of Mapefloor CPU/MF. Wait at least 12 hours at +20°C, depending on the actual site conditions; the scratch coat of Mapefloor CPU/MF must never be sticky. A coat of primer or skim coat is not required on substrates that are not particularly porous if the coat of Mapefloor CPU/MF is broadcast with quartz sand to obtain a non-slip finish. Preparation of the product Pour component A into a large, clean container and, after mixing it, add component B and mix again with an electric mixer at low speed until it is completely blended. Then add component C and Mapecolor CPU powered colouring agent slowly and gradually (one 5 kg bag of Mapefloor CPU for every kit of Mapefloor CPU/MF A+B+C) and continue mixing until an even coloured mix is obtained. We recommend a specific low speed mortar mixer for this operation, such as a vertical mixer or a mixer with static blades and a rotating mixing drum. Apply the mix within the pot life indicated in the table (refers to a temperature of +20°C). Higher surrounding temperatures will reduce the pot life of the mix, while lower temperatures will increase its pot life. Application of the product Smooth self-levelling coating Pour Mapefloor CPU/MF  onto the floor and spread it out evenly to the thickness required, from 3 to 6 mm, with a smooth or notched trowel or a float with spacers.
Immediately after applying Mapefloor CPU/MF, backroll intensively with a spiked-roller to remove entrapped air and reach an even surface. Rough broadcast coating Pour Mapefloor CPU/MF onto the floor and spread it out evenly to the thickness required, from 3 to 6 mm, with a smooth or notched trowel or a float with spacers. Immediately after spreading Mapefloor CPU/MF, broadcast with Quartz 0.5 to obtain a rough surface finish. To obtain an even rougher finish with better non-slip properties, quartz sand with a larger particle size may be used.

MAPEFLOOR PARKING SYSTEM ID is used for the following:
• multi-storey car parks with high flow of traffic;
• transit areas for garages;
• garages.
 

[read more]

PERFORMANCE AND ADVANTAGES
• High crack-bridging capacity at temperatures down to -10°C (static crack-bridging: the capacity to support movements in structures due to thermohygrometric variations; dynamic crackbridging: the capacity to withstand mechanical stress).
• Complies with the requirements of Class OS 13 (according to EN 1504-2).
• Surfaces treated with this system become waterproof (within the limits of the system’s crack-bridging capacity during settling of the substrate).
• Good resistance to mechanical stress.
• Non-slip finish.
• Durable thanks to its characteristic high resistance to wear and abrasion from the constant passage of traffic.
• Easy maintenance.
• Forms attractive, flat, seamless, highly functional surfaces.
CHEMICAL RESISTANCE
Surfaces coated with MAPEFLOOR PARKING SYSTEM ID are resistant to:
• diluted inorganic acids;
• diluted alkalis and detergents normally used for cleaning floors;
• mineral oils, diesel, kerosene and petrol;
• saline solutions in general, including those containing de-icing salts.

COLOURS AVAILABLE
MAPEFLOOR PARKING SYSTEM ID is available in the standard RAL colours 1003, 3011, 5007, 5015, 6017, 7000, 7011 and 7035. Requests for other colours not included in this list must be made to MAPEI Technical Services Department.

YIELD
The consumption levels indicated below are for a cycle applied at a temperature of between +15°C and +25°C and 80% maximum R.H. on the surface of a smooth, dry, compact, cured concrete screed with no rising damp strong enough to withstand the loads to which it will be subjected when in service, with a quartz sand finish polished with a diamond disk or lightly shot-blasted. Rougher surfaces and lower temperatures lead to higher consumption of the products, longer hardening times and longer delays before being put into service. The consumption of PRIMER SN in particular may vary, depending on the type and depth of the treatment method employed to prepare the substrate.
Consumption of the products and materials is heavily influenced by the absorption, roughness and porosity of the substrate and the surrounding conditions on site during application.

SURFACE PREPARATION
1. Characteristics of the substrate Before applying the MAPEFLOOR PARKING SYSTEM ID cycle, the substrate on which the coating is to be applied must be carefully checked. The concrete screed of the substrate must be sound, compact, strong and clean and must be dimensioned according to the static and dynamic loads to which it will be subjected when in service. The flatness must be defined according to the final use.
• To get the best results make sure the substrate has been sufficiently saturated, smoothed over and levelled off with PRIMER SN.
• There must be no materials or debris on the substrate which could potentially impede adhesion of the coating, such as:
– cement laitance;
– dust or detached or loose portions;
– protective wax, curing products, paraffin or efflorescence;
– oil stains or layers of dirty resin;
– traces of paint or chemical products.
Any other kind of pollutant which may compromise adhesion of the coating must be removed before starting work. If the substrate is polluted by such elements, it MUST be prepared by carrying out a specific preparation cycle. If required, contact Mapei Technical Services Department for advice on the most suitable preparation cycle.
• The pull-off strength of the substrate must be higher than 1.5 N/mm².
• The maximum residual moisture content in the substrate must be 4% and a vapour barrier must be included. For floors that have just been installed, wait until the concrete is fully cured before applying the resin system. If the residual moisture content is higher than 4%, apply TRIBLOCK TMB before the MAPEFLOOR PARKING SYSTEM ID coating cycle to prevent detachment and/ or the formation of blisters. If all the above conditions are met, the system may be applied on concrete industrial floors, conventional or polymer-modified cementitious screeds, controlled-shrinkage screeds such as those made using MAPECEM or TOPCEM and old cement blocks and ceramic tiles, if prepared according to specification.
2. Preparation of the substrate
It is very important that the surface is prepared according to specification to guarantee correct application of the system and achieve the best performance levels. The most suitable method to prepare the surface is shot-blasting, or alternatively grinding with a diamond disk. All dust must then be removed with a vacuum cleaner. Do not use chemical preparation methods, such as acid rinsing, or aggressive percussion tools, to prevent damaging the substrate. Any defects present on the surface, such as holes, pitting, cracking, etc., must be repaired beforehand using either EPORIP or PRIMER SN, depending on the width and depth of the defects and cracks. If the substrate needs to be consolidated, use PRIMER MF or PRIMER EP (choose the most suitable product according to the porosity of the substrate, which will also have an effect on the consumption rate). If deep hollows or highly deteriorated areas are present on the surface of the floor, repair these areas using MAPEFLOOR EP19 three-component epoxy mortar or with products from the MAPEGROUT line. Highly deteriorated joints must be reconstructed using the same products. If any of the above conditions are not strictly adhered to, the quality of the coating may be poor.
3. Preliminary checks before application
Make sure that all the checks from point 1 “Characteristics of the substrate” have been made and that all the operations indicated in point 2 Preparation of the substrate” have been carried out correctly. The surrounding temperature must be higher than +8°C (the ideal application temperature is between +15°C and +25°C) and the temperature of the substrate must be at least +3°C higher than the dew-point temperature. Relative humidity of the surrounding air must be no higher than 80%.
4. Preparation and application of the products Carefully follow the preparation instructions according to the Technical Data Sheet for each single product used to form the complete system: PRIMER SN, MAPEFLOOR PU 410 and MAPEFLOOR FINISH 415. Non-slip multi-layered coating - 2-2.5 mm
• Primer (PRIMER SN) Pour component B (4 kg) into component A (16 kg) and mix with a drill at lowspeed (300-400 rpm) with a spiral mixing attachment for at least 2 minutes to form a smooth, even compound. While mixing, add 4 kg of QUARTZ 0.5 to the compound as soon as it has been prepared and continue mixing for several minutes to form a smooth, even compound. Pour the product onto the floor to be coated and spread it out evenly and uniformly by means of a straight trowel or rake. After that, broadcast in excess with QUARTZ 0.5.
• Removal of excess sand Once the PRIMER SN has hardened remove all excess sand with an industrial vacuum cleaner.
• Intermediate layer (MAPEFLOOR PU 410) Pour component A (3.9 kg) into component B (16 kg), add 1.4 kg of MAPECOLOR PASTE and mix with a drill at low speed (300-400 rpm) with a spiral mixing attachment for at least 2 minutes to form a smooth, even compound. Whilst mixing, add 30% in weight of QUARTZ 0.25 to the compound as soon as it has been prepared and continue mixing to form a smooth, even compound. Pour the product on the previous layer and spread it out evenly and uniformly using a notched trowel. While the product is still wet, dust the surface with an even layer of QUARTZ 0.5 or 0.3-0.9 mm or 0.7-1.2 mm quartz sand, depending on degree of non-slip finish required (approximately 4-6 kg/m²).
• Removal of excess sand Once hardened remove all excess sand with an industrial vacuum cleaner.
• Finishing layer (MAPEFLOOR FINISH 415) Pour component B (6.3 kg) into component A (13.7 kg) and mix with a drill at low speed (300-400 rpm) with a spiral mixing attachment for at least 2 minutes to form a smooth, even compound. Apply the product uniformly and continuously using a medium-haired roller, or smooth it over the surface with a smooth rubber or steel trowel, then pass over the surface with a medium-haired roller, aking sure that the roll strokes criss-cross over each other. Any expansion and contraction joints in the floor (contraction joints may be sealed at the start of work and then covered with the resin system) must be sealed with MAPEFLEX PU 45.
5. Hardening and step-on times
At +20°C MAPEFLOOR PARKING SYSTEM ID sets to foot traffic after around 24 hours, while it takes around 3 days before light traffic may use the  surface. Complete hardening and maximum strength are reached after around one week. Lower temperatures lead to longer hardening times and set to foot traffic times for the coating, while higher temperatures reduce these times.
6. Please note
Protect MAPEFLOOR PARKING SYSTEM ID from water and condensation for at least 24 hours after application. If the coating is exposed to aggressive chemicals it may yellow or the colour may change slightly. This phenomenon is purely aesthetic and has no effect on the performance of the system. Do not apply the system if there is a high level of humidity in the surrounding air or, in the case of external applications, if it is about to rain. Wear suitable clothing and sweat bands to prevent beads of sweat dripping onto the surface of the wet resin while it is being applied; it may react with the product and form foam. Never use tools which have just been cleaned with alcohol to apply the products, particularly rollers. We recommend using new rollers. Never dilute any of the products.
CLEANING AND MAINTENANCE
Regular cleaning and maintenance increases the life of the treated floor, improves its aesthetic properties and reduces its tendency to collect dirt. Floors created using MAPEFLOOR PARKING SYSTEM ID are generally easy to clean with neutral detergents, or with alkali detergents diluted at a concentration of from 5 to 10% in water. MAPEFLOOR MAINTENANCE KIT is available for maintenance operations and includes MAPELUX LUCIDA metallic wax, MAPEFLOOR WAX REMOVER and MAPEFLOOR CLEANER ED detergent for daily cleaning operations. Our Technical Services Department is available for any information required.

NOTES
Recommendations regarding safe handling of the products are contained in the Material Safety Data Sheet for each single product in the cycle. However, the use of protective gloves and goggles is recommended when mixing and applying the products.

Mapefloor Parking System HE

MAPEFLOOR PARKING SYSTEM HE is a seamless, flexible, multi-layered polyurethane surfacecoating system compliant with the requirements of Class OS 11a (EN 1504-2). It is suitable for moving vehicles and has a high crack-bridging capacity, a non-slip finish and is resistant to intense volumes of traffic in areas used for car parks, including external car parks. It also has a waterproofing effect for screeds on roof-top car parks.
MAPEFLOOR PARKING SYSTEM HE is characterised by its excellent resistance to wear, mechanical stress in general, UV rays and chemical products such as oil, fuel, de-icing salts, lubricants, diluted acids and base solutions and saline solutions in general. Different colour finishes may be obtained which makes it extremely versatile for marking out areas according to their different use, such as parking areas, transit lanes, pedestrian areas, road signs and markings, etc.

WHERE TO USE
Flexible coating for internal and external concrete floors and cracked cementitious substrates, or those at risk of cracking, such as road surfaces in covered car parks, multi-storey car parks, on bridges and on ramps.

MAPEFLOOR PARKING SYSTEM HE is used for the following:
• multi-storey car parks with an intense flow of traffic;
• bridges, ramps and roof-top car parks;
• on concrete substrates where the surface coating needs to be highly flexible and waterproof;
• communal courtyards over garage spaces.

YIELD
The consumption levels indicated below are for a cycle applied at a temperature of between +15°C and +25°C and 80% maximum R.H. on the surface of a smooth, dry, compact, cured concrete screed with no rising damp strong enough to withstand the loads to which it will be subjected when in service, with a quartz sand finish polished with a diamond disk or lightly shot-blasted. Rougher surfaces and lower temperatures lead to higher consumption of the products, longer hardening times and longer delays before being put into service. The consumption of PRIMER SN in particular may vary, depending on the type and depth of the treatment method employed to prepare the substrate.

SURFACE PREPARATION
1. Characteristics of the substrate Before applying the MAPEFLOOR PARKING SYSTEM HE cycle, the substrate on which the coating is to be applied must be carefully checked. The concrete screed of the substrate must be sound, compact, strong and clean and must be dimensioned according to the static and dynamic loads to which it will be subjected when in service. The flatness must be defined according to the final use. To get the best results the following must be checked:
• The substrate must be sufficiently saturated, smoothed over and levelled off with PRIMER SN.
• There must be no materials or debris on the substrate which could potentially impede adhesion of the coating, such as:
– cement laitance;
– dust or detached or loose portions;
– protective wax, curing products, paraffin or efflorescence;
– oil stains or layers of dirty resin;
– traces of paint or chemical products.
Any other kind of pollutant which may compromise adhesion of the coating must be removed before starting work. If the substrate is polluted by such elements, it MUST be prepared by carrying out a specific preparation cycle. If required, contact Mapei Technical Services Department for advice on the most suitable preparation cycle.
• The pull-off strength of the substrate must be higher than 1.5 N/mm².
• The maximum residual moisture content in the substrate must be 4% and a vapour barrier must be included. For floors that have just been installed, wait until the concrete is fully cured before applying the resin system. If the residual moisture content is higher than 4%, apply TRIBLOCK TMB before the MAPEFLOOR PARKING SYSTEM HE coating cycle to prevent detachment and/ or the formation of blisters. If all the above conditions are met, the system may be applied on concrete industrial floors, conventional or polymer-modified cementitious screeds, controlled-shrinkage screeds such as those made using MAPECEM or TOPCEM and old cement blocks and ceramic tiles, if prepared according to specification.
2. Preparation of the substrate
It is very important that the surface is prepared according to specification to guarantee correct application of the system and achieve the best performance levels. The most suitable method to prepare the surface is shot-blasting, or alternatively grinding with a diamond disk. All dust must then be removed with a vacuum cleaner. Do not use chemical preparation methods, such as acid rinsing, or aggressive percussion tools, to prevent damaging the substrate. Any defects present on the surface, such as holes, pitting, cracking, etc., must be repaired beforehand using either EPORIP or PRIMER SN, depending on the width and depth of the defects and cracks. If the substrate needs to be consolidated, use PRIMER MF or PRIMER EP (choose the most suitable product according to the porosity of the substrate, which will also have an effect on the consumption rate). If deep hollows or highly deteriorated areas are present on the surface of the floor, repair these areas using MAPEFLOOR EP19 three-component epoxy mortar or with products from the MAPEGROUT line. Highly deteriorated joints must be reconstructed using the same products. If any of the above conditions are not strictly adhered to, the final quality of the coating may be poor.
3. Preliminary checks before application
Make sure that all the checks from point 1 “Characteristics of the substrate” have been made and that all the operations indicated in point 2 “Preparation of the substrate” have been carried out correctly. The surrounding temperature must be higher than +8°C (the ideal application temperature is between +15°C and +25°C) and the temperature of the substrate must be at least +3°C higher than the dew-point temperature. Relative humidity of the surrounding air must be no higher than 80%.
4. Preparation and application
of the products Carefully follow the preparation instructions according to the Technical Data Sheet for each single product used to form the complete system: PRIMER SN, MAPEFLOOR PU 400, MAPEFLOOR PU 410 and MAPEFLOOR FINISH 451. Non-slip multi-layered coating - 3-3.5 mm
• Primer (PRIMER SN) Pour component B (4 kg) into component A (16 kg) and mix with a drill at lowspeed (300-400 rpm) with a spiral mixing attachment for at least 2 minutes to form a smooth, even compound. Whilst mixing, add 4 kg of QUARTZ 0.5 to the compound as soon as it has been prepared and continue mixing for several minutes to form a smooth, even compound. Pour the product onto the floor to be coated and spread it out evenly and uniformly by means of  straight trowel or rake. After that full broadcast with QUARTZ 0.5.
• Removal of excess sand Once PRIMER SN has hardened remove all excess sand with an industrial vacuum cleaner.
• Flexible intermediate layer (MAPEFLOOR PU 400) Pour component A (4.75 kg) into component B (15 kg) and mix with a drill at low-speed (300-400 rpm) with a spiral mixing attachment for at least 2 minutes to form a smooth, even compound. While mixing, add 20-30% in weight of QUARTZ 0.25 to the compound as soon as it has been prepared and continue mixing to form a smooth, even compound. Pour the product on the previous layer and spread it out evenly and uniformly using a notched trowel.
• Protective intermediate layer (MAPEFLOOR PU 410) Pour component B (3.9 kg) into component A (16 kg), add 1.4 kg of MAPECOLOR PASTE and mix with a drill at low speed (300-400 rpm) with a spiral mixing attachment for at least 2 minutes to form a smooth, even compound. While mixing, add 30% in weight of QUARTZ 0.25 to the compound as soon as it has been prepared and continue mixing to form a smooth, even compound. Pour the product on the previous layer and spread it out evenly and uniformly by means of a straight trowel or rake. After that full broadcast with QUARTZ 0.5 or 0.3-0.9 mm or 0.7-1.2 mm quartz sand, depending on degree of non-slip finish required (approximately 4-6 kg/m²).
• Removal of excess sand Once hardened remove all excess sand with an industrial vacuum cleaner.
• Finishing layer (MAPEFLOOR FINISH 451) Pour component B (6 kg) into component A (14 kg) and mix with a drill at low speed (300-400 rpm) with a spiral mixing attachment for at least 2 minutes to form a smooth, even compound. Apply the product uniformly and continuously using a medium-haired roller, or smooth it over the surface with a smooth rubber or steel trowel, then pass over the surface with a medium-haired roller, making sure that the roll strokes criss-cross over each other. Any expansion and contraction joints in the floor (contraction joints may be sealed at the start of work and then covered with the resin system) must be sealed with MAPEFLEX PU 45.
5. Hardening and step-on times
At +20°C MAPEFLOOR PARKING SYSTEM HE sets to foot traffic after around 24 hours, while it takes around 3 days before light traffic may use the surface. Complete hardening and maximum strength are reached after around one week. Lower temperatures lead to longer hardening times and set to foot traffic times for the coating, while higher temperatures reduce these times.
6. Please note
Protect MAPEFLOOR PARKING SYSTEM HE from water and condensation for at least 24 hours after application. If the coating is exposed to aggressive chemicals it may yellow or the colour may change slightly. This phenomenon is purely aesthetic and has no effect on the performance of the system. Do not apply the system if there is a high level of humidity in the surrounding air or, in the case of external applications, if it is about to rain. Wear suitable clothing and sweat bands to prevent beads of sweat dripping onto the surface of the wet resin while it is being applied; it may react with the product and form foam. Never use tools which have just been cleaned with alcohol to apply the products, particularly rollers. We recommend using new rollers. Never dilute any of the products.
