Elakor-PU Grunt-50/T — thixotropic polyurethane primer for walls

Floor primers

This thixotropic modification of the impregnating primer is needed where the polyurethane floor system continues onto walls, ceilings and plinths. The material does not run even from a ceiling and is applied by roller, brush, air or airless spraying onto concrete, brick, slate, stone, wood, particleboard and cement-bonded particleboard. 1–2 coats are enough under a coating, while 2–3 coats are used as an impregnation; film tensile strength is at least 65 MPa, adhesion to concrete 6.2 MPa, fire hazard class KM1.
