LEVL Coat 154 Rapid — fast-drying polyurethane primer
One-component primer-impregnation for concrete and metal under polyurethane floors; next coat at +20 °C after just 3 hours.

LEVL Coat 102W primer makes it possible to lay a polymer floor on damp or fresh concrete: it works on substrates with moisture up to 10 % by weight and on “young” concrete from 7 days. The water-based epoxy compound without organic solvents serves as a temporary moisture barrier under epoxy and polyurethane coatings, is vapour-permeable and odourless. It is applied with a velour roller, flat trowel or brush in two or more coats; tools are washed with water. Adhesion to concrete is at least 2 MPa, service from −10 to +60 °C.
