Agent for priming mineral substrates, used prior to applying permanent MITECH 3721 coating. Intended for the majority of materials: e.g.: concrete, sandstone, limestone, AmerBlok, brickwork, renders: thin-layer, cement-lime, mosaics , etc. Effectively removes graffiti and reduces the excessive penetration of the said coatings into the substrate, which minimises discolouration changes, façade darkening (wet surface effect), definitely improving the aesthetics of the coating. It is also intended for reinforcing fragile, crumbly, unstable substrates and can be used prior to applying other paint coats. For use indoors and outdoors at temperatures above zero centigrade. The product has a Technical Approval of the Road and Bridge Research Institute (lBDiM), Warsaw.
