Elakor-PU Grunt SK PROF — impregnating primer of the professional line

Floor primers

The SK PROF line primer is supplied ready to use and cures by air moisture, forming a transparent amber film with a gloss of 82–87 %. It primes concrete, terrazzo, tile, cement self-levelling floors, brick, wood and plywood under any polyurethane coatings, or works as a stand-alone protective impregnation. Adhesion to concrete is 6.2 MPa, to magnesia concrete 3.68 MPa, fire hazard class KM1 (V1, D1, T2, RP1); according to the technical data sheet, the primer is approved for food and pharmaceutical plants and healthcare institutions.
