BIRSS Kontakt — epoxy impregnation-hardener for concrete floors

Concrete impregnations and hardeners

This colourless waterborne compound suits both freshly laid floors, including those with a topping, and mature concrete. On young concrete the impregnation slows moisture evaporation, while on old concrete it hardens the surface; work is possible indoors and outdoors. For finished floors on UK-1 and UK-2 toppings the manufacturer recommends Kontakt as a protective layer; bond to concrete is at least 2.0 MPa.
