Waterproofing bituminous emulsion
Bitupast
Bitupast is a waterproofing bituminous emulsion (paste) with resins and mineral stabilisers. It has excellent adhesion to construction materials. The film formed after application and drying is resistant to dilute solutions of acids and bases, unaffected by soil salts, but vulnerable to organic solvents, oils, and strong chemical cleaners.
It is user- and environmentally friendly because it contains no solvents. It is diluted with water. It is compatible with polyurethane, polystyrene, concrete, metal, and wooden surfaces. The product’s properties meet the requirements of ASTM D-1227, Type III, Class 2.
