Features & Benefits

• Mapefloor Pore Filler a two-component polyurethane resin-based formulate according to a formula developed in the MAPEI R&D Laboratories
• High bond strength, does not shrink during the hardening phase and its final level of elasticity is compatible with the amount of deformability typical of the floor covering systems Mapefloor Comfort System AR/X and Mapefloor Comfort System AL/X

Preparation

• Mapefloor Pore Filler may be applied on dry, well cured, cementitious substrates. The minimum compressive and tensile strength of the substrate must be 25 N/mm² and 1.5 N/mm² respectively, and it must always be strong enough for the final design use
• Remove all loose or crumbling areas mechanically
• The surface of ceramic or natural stone substrates must be roughened with a diamond grinding disk or by shot blasting to remove all traces of enamel and polish
• Any cracks must be repaired by filling them with Eporip, while any deteriorated areas of the concrete must be repaired with Mapefloor EP19 or a cementitious mortar from the Mapegrout range
• Before applying Mapefloor Pore Filler, remove all traces of dust from the surface with a vacuum cleaner
• Mix component A thoroughly and then add component B and mix again with an electric mixer at low speed until it is completely blended

Application

Bonding

Pour the product over the surface of the prepared flooring and spread it out evenly with a 3-4 mm notched trowel. While the adhesive is still wet, and within the open time specified in the technical data table, lay the special Mape Comfort matting made from rubber granules and press it down firmly so that the adhesive penetrates between the granules. For further details on how to lay Mape Comfort refer to the relative Technical Data Sheet.

Filling pores and smoothing

When the layer of adhesive has hardened, pour Mapefloor Pore Filler over the Mape Comfort and spread it out evenly with a straight steel or plastic trowel, making sure it penetrates into the pores in the substrate. We recommend spreading the product lengthways along the matting, smoothing over the whole width of the strips and the joints between adjacent pieces of matting. Smooth over the joints a second time when applying the product on the adjacent strips. Make sure all joints between the matting and walls and other vertical elements and members are completely filled with Mapefloor Pore Filler. The product may also be used to fill any small holes in the layer of matting.

To ensure the pores in the Mape Comfort are completely saturated, a second smoothing layer of Mapefloor Pore Filler may be applied once the first one has hardened.

Coverage around 0.4÷0.8 kg/m² when used as adhesive - actual consumption is heavily influenced by the type of substrate - and 0.4÷0.5 kg/m² when used to smooth over Mape Comfort. Cleaning tools used to prepare and apply Mapefloor Pore Filler with thinner for polyurethane products immediately after use. Once hardened the product may only be removed using mechanical means.

Limitations

• Do not apply Mapefloor Pore Filler on substrates with a film of surface water or on concrete that is damp or not fully cured. · Do not dilute Mapefloor Pore Filler with solvent or water
• Do not apply Mapefloor Pore Filler on dusty or crumbling substrates
• Do not apply Mapefloor Pore Filler on substrates with oil or grease stains or any contaminations
• Do not apply Mapefloor Pore Filler 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
• Protect the product 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
