Use Silcor Primer BS 117 for: Priming concrete, masonry, and metal surfaces before applying Silcor polyurea and polyurethane waterproofing membranes and protective coatings.
Silcor Primer BS 117 is a one-part, fast-curing, solvent-based primer specifically designed to enhance the adhesion of Silcor polyurea and polyurethane membranes and coatings to various substrates, including concrete, masonry, and metal. Its high penetration and low viscosity ensure a strong bond and effective sealing of surface porosity, reducing the risk of outgassing and pinholes. Silcor Primer BS 117 is ideal for use in exposed, non-exposed, and permanent immersion areas, making it a versatile solution for a wide range of waterproofing applications.
