Description

Sikafloor®-81 EpoCem® is a three part, epoxy modified cementitious, fine textured mortar for self smoothing floor screeds in thin layers of 1.5 to 3 mm.

Uses

Sikafloor®-81 EpoCem® may only be used by experienced professionals.

• As a Temporary Moisture Barrier (TMB) (min. 2 mm thick) allowing the application of Epoxy, Polyurethane and PMMA* resin floors requiring dry substrates, over high moisture content substrates, even green concrete, for a lasting solution.

As a self-smoothing screed for:

• Levelling or patching horizontal concrete surfaces, in new work or repairs, in aggressive chemical environments
• Floor topping on non ventilated damp substrates without particular aesthetic requirements
• Levelling layer under Epoxy, Polyurethane and PMMA* floor coatings / screeds, tiles, sheet floors, carpets or wooden floors
• Repair and maintenance of monolithic and vacuum concrete floors

Designed for use on cementitious substrates:

• Suitable for moisture control (Principle 2, method 2.3 of EN 1504-9)
• Suitable for physical resistance (Principle 5, method 5.1 of EN 1504-9)

Advantages

• Can be top coated with resin based floors after 24 hours (+20ºC, 75% r.h.)
• Prevents osmotic blistering of resin based coatings over damp substrates
• Economical and fast, easy application
• Good levelling properties
• Impervious to liquids but permeable to water vapour
• Frost and de-icing salt resistant
• Good chemical resistance
• Thermal expansion properties similar to concrete
• Excellent bond to green or hardened concrete whether damp or dry
• Excellent early and final mechanical strengths
• Excellent resistance to water and oils
• Ideal preparation for smooth surface finishes
• For internal use
• Contains no solvents
