Designed for priming concrete, reinforced concrete, cement-sand, metal, and other surfaces before applying roofing and waterproofing materials. Used for preparing structural surfaces before applying vapor and waterproofing layers, as well as for waterproofing protection of metal and concrete surfaces. Provides deep penetration into the substrate and improves adhesion with subsequent coatings. Consumption: 0.6–1.0 kg/m². Standard: DSTU B V.2.7-108-2001. Packaging type: plastic bucket. Advantages: — deep penetration and surface strengthening; — enhances adhesion of waterproofing materials; — reduces substrate moisture absorption; — easy to apply with brush, roller, or sprayer.
