Bitumen Prime Coating
Roofing & Waterproofing Solution

Bitumen Prime Coating

Bitumen Prime Coating is a ready-to-use surface primer developed for preparing porous, rough and dusty surfaces before installing bitumen roofing and waterproofing materials.

Its high-quality bitumen and specially selected organic solvent formulation provides excellent covering capacity, deep penetration and strong adhesion between the surface and waterproofing membrane.

The coating can be applied directly using a roller, large brush or small brush. No additional mixing or surface treatment is normally required before application.
