Bitumen Primer is a low viscosity, high penetration, cold applied bituminous solution designed to prime and seal porous roof surfaces prior to the application of covering materials. Geochem General Purpose Bitumen Primer seals porous substrates and promotes the adhesion of bituminous waterproofing systems and sheet coverings. It can be applied to a wide range of surfaces including: concrete, asbestos cement, Metal (mild steel, zinc, lead), slate and lightweight concrete screeds.
The primer serves as the bridge between the substrate and the AR lining. It penetrates and bonds to the substrate and builds up a continuous film on the surface.
