Features & Benefits

Mapefloor CPU+/MF provides a protective resin system for industrial floors.

Use to create smooth polyurethane-cement based systems with a light no slip property, or as base layer for rough multi-layer systems (Mapefloor System CPU+/DP) for industrial floors, especially in dry or even occasionally wet (for short periods) production and logistic areas, where a durable, resistant and easy to clean and sanitise surface is required.

Mapefloor CPU+/MF is typically used in the chemical and pharmaceutical, textile and tanning industries, canning in general, sugar refineries, dairies, wineries and beverage companies in general, meat and fish processing, production and storage areas of food companies in general, commercial and industrial kitchens, freezing rooms and wherever high mechanical and chemical spillages and contact to hot liquids resistances are required.

• Depending on the thickness applied, resistant to thermal shocks due for example to spillage of hot liquids:
  
  • 3 mm: -10°C up to +60°C
  • 4 mm: -15°C up to +70°C
  • 6 mm: -25°C up to +80°C
• 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 Global Green Tag. Classified A+, the best class for the lowest emissions
• 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
• Easy to sanitise
• Non-tainting for food
• Fast return to service
• 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
• Mapefloor CPU+/MF can be applied both as a self-smoothing and as the basecoat of the multilayer defined profile system (Mapefloor System CPU+/DP)

Recommendations & Limitations

• Mapefloor CPU+/MF 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+/MF on wet substrate or on concrete younger than 7 days
• 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 dirt 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 without having previously prepared the surface according to specification
• Mapefloor CPU+/MF 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+/MF 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/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

Application & Preparation

Substrate characteristics:

• Substrate must be solid, compact, stable, healthy, 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 the Mapefloor CPU+/MF
• 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+/MF) 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:

• Mapefloor CPU+/MF must be applied on a substrate with no surface porosity to prevent pinholes in the hardened product
• For such reason a preliminary layer of Mapefloor CPU+/Primer must be applied
• Alternatively, Primer SN fully broadcast with quartz sand Quartz 0.9 can be used as well but only for fully cured and dry substrates with a humidity content < 4% and when no thermal shocks are expected during the service life of the floor
• In case of rough surface, apply a scratch coat using Mapefloor CPU+/MF to even the surface
• For further information about preparation, mixing, consumption and application details of Mapefloor CPU+/Primer and Primer SN, please read the related Technical Data Sheets

Product preparation:

• Shake the packs containing the liquid components A, B and Mapecolor CPU+ pigment
• Pour two packs of component A and two packs of Mapecolor CPU+ into a clean bucket and mix for a few seconds until a homogeneous mixture is obtained
• Then add two packs of component B and mix again with a suitable low-speed electric mixer until completely homogenized
• Then slowly and gradually add one pack of 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
• 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+/MF on the floor and spread it evenly to the required thickness with a straight or serrated trowel or a squeegee fitted with thickness rulers
• 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 minimized
• Immediately after spreading, it is necessary to move spike roller several times to remove any air trapped during mixing and help the material smoothing
• 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 the pot life

Consumption:

• As scratch coat 1 mm thickness:
  
  • Mapefloor CPU+/MF: approx. 1.7 kg/m²
• As self-smoothing layer:
  • Mapefloor CPU+/MF 3 mm: approx. 5.5 kg/m²
  • Mapefloor CPU+/MF 4 mm: approx. 7 kg/m²
  • Mapefloor CPU+/MF 6 mm: approx. 10 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

Tools 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+/MF 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
