Sikafloor®-81 EpoCem®

Sikafloor 81 EpoCem is a three-component, solvent-free, odorless, moisture-tolerant, epoxy modified, cementitious self-leveling mortar. Specifically formulated for leveling and structural reprofiling of damp, “green” or saturated surface dry concrete slabs, and slabs with excessive water vapor transmission rates at thicknesses of 120 - 160 mil (3 - 4 mm).

■ As a positive side vapor barrier prior to use with Sikafloor systems.
■ Economical structural resurfacing compound.
■ Water-based, solvent-free and odorless.
■ Self-leveling and good flowability.
■ Can be overcoated with epoxy resin compounds after 24 hrs [(68°F (20°C) at 50% relative ambient humidity]. Surface moisture measured with a Tramex® CME/CMExpert type concrete moisture meter must be < 4% prior to application of epoxy resin compound.
■ Waterproof yet permeable to water vapor.
■ Prevents osmotic blistering of resin based coatings over damp substrates
■ Fast curing and high early strengths.
■ Excellent adhesion to dry, damp, green or saturated surface dry concrete substrates.
■ Modulus of elasticity and coefficient of thermal expansion comparable to concrete.
■ Good adhesion after long-term water immersion in conjuction with suitable Sika coating system.
■ Contains no solvents.

Usage

As a Temporary Moisture Barrier (TMB) minimum 120 mils (3 mm thick) under Epoxy, Polyurethane and Methyl Methcrylate (MMA) resin floors, over high moisture content substrates; even green concrete. Note: Sikafloor 81 EpoCem must be sealed with a suitable Sikafloor epoxy primer system (e.g. Sikafloor 107, Sikafloor 160 and Sikafloor 161 at 16 mils) to form a long term vapor barrier. As a self-smoothing screed for:
■ Specifically formulated for leveling and structural reprofiling or patching horizontal concrete surfaces, in new work or repairs
■ Floor topping on unventilated, damp substrates with no aesthetic requirements
■ Leveling layer under Epoxy, Polyurethane and MMA floor coatings /screeds, tiles, sheet floors, carpets or wooden floors
■ Repair and maintenance of monolithic concrete floors
■ Extend with oven-dried quartz sand as a patching and repair mortar
