Bitumen Primer COATING is intended for preparation of the surface before installation of bitumen roofing and waterproofing materials. The prime coating is necessary for ensuring the strong adhesion of the bitumen-based waterproofing materials to porous, rough and dusty surfaces. The primer presents a mix of high-quality bitumen and specially selected organic solvents. It has a good covering capacity and penetrability.
Primer is applied to a surface by roller, large or small brush. It is applied to the base at once that grants additional convenience and enhanced performance.
The product should be stored in a dry place protected from direct sunlight at temperatures from -20°C to +30°C.
