Elakor-PU Lak for Stone, Brick — polyurethane impregnation with a wet stone effect

Sealers and topcoats

This one-component varnish impregnates stone, brick, concrete, concrete tile and slate, brings out their texture and gives the surface a “wet stone” effect. The coating protects against atmospheric, mechanical and chemical attack and makes scratches less visible; 2–3 coats until a uniform sheen are usually enough. It can be applied at temperatures from −30 to +25 °C, substrate moisture not more than 5 %; according to the technical data sheet, the varnish is additionally certified for residential buildings, children’s and healthcare institutions and food plants.
