Recommendations & Limitations

• Mapefloor CPU+/HD 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+/HD on wet substrate or on concrete younger than 7 days
• 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 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+/HD 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 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 the coating from water for at least 24 hours after application

Application & Preparation

Substrate characteristics:

• Substrate must be solid, compact, stable, sound, clean, and properly designed for static and dynamic loads foreseen in the operating conditions
• The flatness must be defined by the needs of use
• At the time of application, compressive strength of the concrete or cementitious mortar used for the repair must be higher than 25 N/mm² and the direct tensile strength at least 1.5 N/mm²
• The substrate surface must appear visually dry
• There must be no capillary rising damp as well (verify with the polythene sheet test)
• In the case of substrate such as ceramic tiles, natural stones, or old resinous coatings, they must be perfectly stable and anchored to the substrate, intact, healthy, and clean
• These substrates require specific preparation methods for the laying surfaces
• In the case of old resinous coatings, it is recommended to also perform a compatibility test with the new system to be applied

Substrate preparation:

• The surface of the floor must be prepared with specific mechanical equipment such as for example shotblasting or milling machine, to remove all traces of dirt, any contamination for the entire thickness concerned, cement laitance, crumbly or detached parts and make the surface rough and absorbent
• Any defects such as holes, pitting, cracks, etc. they must be repaired using, for example, Primer SN possibly 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

Anchor grooves:

• The anchoring grooves on the concrete must be made with a suitable mechanical joint saw
• The dimensions (depth and width) must be approximately double the thickness of Mapefloor CPU+/HD
• They must be provided along the perimeter of the area, near all the vertical lines such as walls and pillars, around the drainage channels and wells, on the thresholds of the doors, around the feet of the machinery, in general along each free edge and the interruptions of the installation, such as joints that clearly define the end of the working day and the beginning following one
• The maximum distance between parallel grooves must not exceed approximately 15 meters
• If it exceeds this measure, it will be necessary to make intermediate cut
• In case concrete has not fully completed its hygrometric shrinkage, it is advisable to make the anchor grooves also along the cracks control joints
• It will make possible to seal the joint in case the shrinkage crack appears in the joint (therefore also on Mapefloor CPU+/HD) even without removing part of the floor, as the entire area straddling the joint is already well anchored

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

Application of the primer:

• Primer is normally not necessary
• However, in case of substrate that does not require repair or levelling, it’s advisable to use the specific Mapefloor CPU+/Primer to saturate the pores of the concrete surface to prevent the potential formation of pinholes on Mapefloor CPU+/HD
• For further information regarding the preparation, mixing, consumption, and application details of Mapefloor CPU+/Primer, please refer to the related Technical Data Sheet

Product preparation:

• Shake the packs containing the liquid components A, B and Mapecolor CPU+ pigment
• Pour a pack of component A and a pack of Mapecolor CPU+ into a clean bucket and mix for a few seconds until a homogeneous mixture is obtained
• Then add a pack of component B and mix again with a suitable low-speed electric mixer until completely blended
• Then slowly and gradually add all component C, continuing to mix for at least three minutes until a homogeneous mixture is obtained
• We recommend the use of specific low-speed mixers for mortars, such as those with vertical rotation axis or those with static mixing blades and rotating container
• 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

Product application:

• Immediately after mixing, pour all mixed Mapefloor CPU+/HD on the floor and spread it evenly to the required thickness with a straight trowel or a squeegee fitted with thickness rulers
• Once the application has been completed, it is advisable to smooth the surface with a suitable roller
• Excess of working with tools on the surface of Mapefloor CPU+/HD could reduce the roughness of the applied product due to the bleeding of the resin
• It is advisable to proceed with the installation of the product in such a way as to ensure that the material that has just been poured can be connected to the one already laid when the latter is still fresh and workable
• This way the signs of conjunction will be minimised
• Apply the mix within the useful pot life indicated in the table
• The higher the temperature, the lower the pot life, the lower the temperature, the higher the pot life

Consumption:

• Mapefloor CPU+/HD: approx. 2.0 kg/m² per mm thickness
• 6 mm thickness: approx. 12 kg/m²
• 9 mm thickness: approx. 18 kg/m²
• 12 mm thickness: approx. 24 kg/m²
• The consumption is influenced by the roughness and absorption of the substrate as well by the environmental and working conditions of the job site

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+/HD 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

For additional application & technical data please refer to Technical Data Sheet (see 'Data Sheets' section above)
