DESCRIPTION
Sikafloor®-81EpoCem® New HC is a three part, epoxy modified cementitious, fine textured mortar for self smoothing floor screeds in thin layers of 1.5 to 3 mm.USESSikafloor®-81EpoCem® New HC may only be used by experienced professionals.Asa 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.Asa self-smoothing screed for: ▪Levelling orpatching horizontal concrete surfaces, in new work or repairs, in aggressive chemical environments.▪Floor topping onnon-ventilated damp substrateswithout particular aesthetic requirements.▪ Levelling layer underEpoxy, Polyurethane andPMMA*floor coatings / screeds,tiles, sheet floors, carpets or wooden floors.▪Repair andmaintenance of monolithic and vacuum concrete floors.Extended with quartz sand, as a patching and repair mortar :▪Under Epoxy,Polyurethane and PMMA floor coatings / screeds
CHARACTERISTICS/ ADVANTAGES▪ Can be overcoated with epoxy resin compounds after 24 hours (20 °C, 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▪ 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▪ Will not corrode reinforcement
