Product Description

Sika 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.

Best Uses

Sika Sikafloor 81 EpoCem may only be used by experienced professionals. Sika Sikafloor 81 EpoCem is suitable 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.

Sika Sikafloor 81 EpoCem is also suitable 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.

This is also ideal for the repair and maintenance of monolithic and vacuum concrete floors. Sika Sikafloor 81 EpoCem is designed for use on cementitious substrates:
Suitable for moisture control (Principle 2, method 2.3 of EN 1504-9) and suitable for physical resistance (Principle 5, method 5.1 of EN 1504-9)

  • 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
