Product overview
Bostik Penetration Primer is a low-viscosity, solvent-based bituminous solution formulated to penetrate porous roofing substrates and enhance surface adhesion to provide a key prior to the application of bituminous waterproofing coatings.
It is specifically designed for priming substrates such as bitumen roofing felt, concrete roofs, cementitious screeds and renders, mastic asphalt, and weathered corrugated iron and steel. The primer promotes optimal conditions for providing a uniform key for subsequent bituminous coatings.
