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 3mm.
Uses:
- As a Temporary Moisture Barrier (TMB) (min. 2 mm thick) under Epoxy, Polyurethane and PMMA resin floors, over high moisture content substrates, even green concrete.
As a self-smoothing screed for:
- Levelling or patching horizontal concrete surfaces, in new work or repairs, particularly 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
Designed for use on cementitious substrates
* See Notes on Application / Limitations in Data Sheet
Features and Benefits:
- 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
