Bostik BoscoSeal Top – HT is a one-component, ready to use, elastic, semi-rigid, wear resistant, cold applied, aliphatic polyurethane waterproofing top-coating membrane with excellent mechanical and chemical, thermal, UV resistance.
• Crack bridging capability up to 2 mm
• Provides excellent thermal resistance over a temperature span of – 30 ºC to + 90 ºC
• Resistant to salty water, aqueous solution, bases, diluted acids, aliphatic solvents, benzene and mineral oils
• Impregnates by penetrating deeply into all mineral and concrete surfaces with high adherence
• Fills the non-structural capillary cracks by decreasing water-absorbency of the concrete construction
• Hardens the upper surface of the concrete by deeply penetrating into the surfaces
