Specification of SikaFloor 81 Epocem HC
DESCRIPTION
Sikafloor®-81
EpoCem® 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.USES
Sikafloor®-81
EpoCem® New HC 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.
Extended with quartz sand, as a patching and repair mortar :
▪ Under Epoxy,
Polyurethane and PMMA floor coatings / screeds
CHARACTERISTICS

▪ 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
