Elakor-PU Grunt-2K/40 — maximum-depth polyurethane impregnation

Floor primers

Of all the polyurethane primers in the range, this one penetrates the deepest: with a solids content of 40 %, it soaks into the pores of weak concrete and hardens it. It is used under any polyurethane coatings on floors, walls and structures, and also as a stand-alone impregnation in 2–4 coats. Permissible substrate moisture is up to 6 % by weight, the mix keeps its pot life for at least 60 minutes, adhesion to B30 concrete is 2.4 MPa with failure in concrete; use at food and pharmaceutical plants is provided for by the technical data sheet.
