Elakor-PU Grunt-P — pore-filling polyurethane floor primer

Floor primers

This pore-filling primer based on urethane prepolymers with filler closes the pores of concrete, sand concrete, cement self-levelling floors, tile, stone and brick, and is also suitable for wood, plywood, particleboard and cement-bonded particleboard. It is applied under epoxy and polyurethane coatings and, mixed with sand, is used as a filler. Work is possible at air and substrate temperatures from −30 to +25 °C; solids content is at least 62 %, adhesion to concrete is 6.4 MPa with failure in concrete, fire hazard class KM1.
