Specification of SikaFloor 81 Epocem HC 19 kg
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 substrates without particular aesthetic requirements. ▪ Levelling layer underEpoxy, Polyurethane and PMMA* 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
