Features & Benefits

• Mapefloor CPU+/TC is used as the final layer of Mapefloor System CPU+/DP multilayer system or as an optional finishing coat of systems made with the Mapefloor CPU+ range of products
• Mapefloor CPU+/TC can also be used as a coating on concrete and cementitious surfaces in general such as walls, pillars, conduits, connection covings between walls and floors, etc
• Fulfills HACCP requirements.
• Complies with all Indoor Air Comfort Gold emission requirements for indoor flooring systems, including AgBB in Germany, M1 in Finland and Afsset in France, BREEM, CAM, Singapore Green Label and Green Tag Australia. Classified A+, the best class for the lowest emissions
• Ease for warehousing management; components A, B and Mapecolor CPU+ are common to whole Mapefloor CPU+ product range
• Complies with the principles defined in EN 13813 'Screed material and floor screeds - Screed material - Properties and requirements', which specifies the requirements for screed materials used in the construction of internal floors
• Sustainability: it can contribute to LEED credits EPD (Environmental Product Declaration) compliant

Some application examples:

• Finishing layer for polyurethane-cement systems made with smooth Mapefloor CPU+/MF or fully broadcasted with quartz sand as provided in Mapefloor System CPU+/DP, even in wet operating conditions
• Finishing layer of covings for example between walls and floors, made with Mapefloor CPU+/COVE
• Easy to clean and chemical resistant protective coating of concrete walls or cement plaster in food, chemical, pharmaceutical industries, etc
• Optional finishing coat for systems made with Mapefloor CPU+/RT, Mapefloor CPU+/HD, Mapefloor CPU+/NZ, Mapefloor CPU+/UD, Mapefloor CPU+/SR

Recommendations & Limitations

• Mapefloor CPU+/TC must be mixed with the specific Mapecolor CPU+ pigment available in grey, beige, red, green, ochre, blue and orange colour
• Do not apply Mapefloor CPU+/TC on wet substrates or on concrete younger than 7 days
• Do not dilute Mapefloor CPU/TC with solvent or water
• Do not apply Mapefloor CPU/TC on dusty or crumbling substrates
• Do not apply Mapefloor CPU/TC on substrates with oil or grease stains or stains in general
• Do not apply Mapefloor CPU/TC 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/TC on ceramic substrates or stone in general with no appropriate specific preparation of the laying surface
• Mapefloor CPU+/TC exposed to UV lights could lead to noticeable colour changes; this phenomenon does not affect the performance of the coating in any way
• The colour of Mapefloor CPU+/TC can also change in case of contact with certain chemicals, the colour variation itself is not an indication of chemical aggression on the coating
• Remove aggressive chemicals as soon as possible after they come into contact with Mapefloor CPU/TC
• Use suitable specific cleaning equipment and detergent to clean the product, depending on the type of dirt or stain to be removed
• Protect the product from water for at least 24 hours after application

Application & Preparation

Substrate characteristics:

• Mapefloor CPU+/TC can be applied as an optional coat, to homogenize the colour appearance of Mapefloor CPU+ product range application
• Application must take place within 12 hours of hardening at +23°C of the base layer if you want to maintain the resistance to thermal shock with no risk of debonding of Mapefloor CPU+/TC
• After that time, it will be mandatory to mechanically reactivate the surface to be treated with a grinding machine before applying Mapefloor CPU+/TC
• Substrates made up with Mapefloor CPU+ product range must be hardened, no longer sticky, dry, clean and dust-free
• Please read the technical data sheets of the related Mapefloor CPU+ product for further application details
• Mapefloor CPU+/TC can also be used as a coating on concrete and cementitious surfaces in general such as walls, pillars, channels, etc
• These surfaces must be dry or moderately humid, clean, undamaged, without crumbling or detached parts
• The substrate concrete must be at least 15 days old and at the time of application it must have a minimum compressive strength of 25 N/mm² and 1.5 N/mm² tensile strength
• The mechanical performance of the substrate must in any case be adequate for the purpose and for the stresses for the specific operating conditions

Substrate preparation:

• Mechanically remove any loose or crumbly parts
• Cracks can be repaired with Primer SN filled with quartz sand or thixotropic agent like Additix PE or with Mapefloor JA or Mapefloor JA Fast depending on the width and depth of the defects and cracks
• Before proceeding with the application of the material, the surface dust must be carefully vacuumed

Temperature:

• To avoid the condensation on the surface, the substrate temperature must be at least 3°C above the dew point
• The relative humidity of the air must be lower than 80%
• The ambient temperature must be between +10°C and +30°C
• In case of application at temperature above +25°C, store the material in sheltered spot at lower temperature
• This will allow to get longer pot life and get the application simpler even at high temperature
• In case of temperature below +15°C, store the material in a warmer place (heated room temperature) to avoid the risk of too high viscosity of the mix making the application harder and turning into a potential problem of aesthetics effect

Preparation of the product:

• Shake the packs containing the liquid components A, B and Mapecolor CPU+ pigment
• Pour one pack of component A and one pack of Mapecolor CPU+ into a clean bucket and mix for a few seconds until a homogeneous mixture is obtained
• Then add one pack of component B and mix again with a suitable low-speed electric mixer until completely blended
• Then slowly and gradually add one pack of component C, continuing to mix for at least three minutes until a homogeneous mixture is obtained
• At temperatures lower than +23°C this time could be slightly longer
• Only mix whole packs of components A, B, C and Mapecolor CPU+ to prevent potential mistakes in the mixing ratios which could compromise the entire system

Application of the product:

• Mapefloor CPU+/TC can be applied on substrates made with Mapefloor CPU+ products range within 12 hours of their hardening at +23°C
• If this time is exceeded, mechanical preparation of the surface must be carried out
• There is no maximum overcoating time for Mapefloor System CPU+/DP, as long the surface is clean and free from dust
• For better distribution of the material, it is advisable to pour all Mapefloor CPU+/TC onto the floor and apply it evenly with a short or medium pile roller, for example on smooth Mapefloor CPU+/MF or on rough Mapefloor CPU+/RT, Mapefloor CPU+/HD, Mapefloor CPU+/NZ, Mapefloor CPU+/UD and Mapefloor CPU+/SR
• In the case of wall cladding or coving, apply the product in at least two coats
• In the Mapefloor System CPU+/DP system, immediately after mixing, pour all Mapefloor CPU+/TC on the floor
• Then spread the material evenly with a straight squeegee, crossing the strokes to seal the roughness properly
• Finally, use a medium hair roller (50 - 60 cm wide), to even out any excess product and obtain the correct aesthetic and functional result
• Apply the mix within the useful pot life indicated in the table
• The higher temperatures the lower pot life; the lower the temperature, the higher pot life

Consumption:

• As topcoat on concrete or a Mapefloor CPU+ products range:
  • Mapefloor CPU+/TC 0.4 -1.2 kg/m² (depending on the roughness of the substrate)

Tool cleaning:

• Equipment used to prepare and apply Mapefloor CPU+ product range must be cleaned with thinner for polyurethanes immediately after use
• Once the product has hardened, it can only be removed mechanically

Floor cleaning:

• The first cleaning after laying Mapefloor CPU+/TC must only be carried out after the product has completely hardened
• Early washing could lead to the formation of stains/shading due to the surface not yet perfectly closed and still partially absorbent
• For periodic and extraordinary washing, use suitable and specific machines, equipment and detergents for the type of stains and dirt to be removed
