Elakor-PU Grunt SK PROF — impregnating primer of the professional line
Professional version of the one-component polyurethane primer: impregnation and priming of concrete under polyurethane coatings at temperatures down to −30 °C.

This quartz-filled two-component compound flows into a glossy coating for workshops, warehouses, car parks and sales floors with impact and vibration loads. It is spread with notched squeegee rakes or trowels over a substrate primed and levelled with “Elakor-PU” materials. Compressive strength is 42 MPa, Shore D hardness 53–58, service temperature from −60 to +80 °C; pouring is carried out at air and substrate temperatures from +5 to +22 °C.
