Polibetol-Grunt — polyurethane primer for concrete floors
One-component strengthening polyurethane primer with almost no odour for Polibetol series enamels; applied from −5 °C.

The “2 in 1” formula combines primer and finish: the first coat fills the pores of the concrete and the second forms the coating, so no separate primer is required. The enamel is thinned with water, is applied to concrete with residual moisture up to 15 % and dries to degree 3 in no more than 1.0 h; it can be walked on after 12 h. Under traffic the coating polishes rather than wears away, and owing to its environmental friendliness the manufacturer recommends it for children’s, pre-school and medical facilities.
