Black-Knight® Primer

Quick-drying, coal tar roof primer provides maximum surface adhesion to metal, concrete, masonry, and existing coal tar-based roof systems.

* This product is sold as Black-Stallion® Primer in Canada

This quick-drying, coal tar roof primer conserves finishing material by conditioning the surface and eliminating the tendency of the finishing material to absorb into the dried out, existing surface. Its unique formulation ensures a long-lasting flexible bond between the existing roof surface and the finishing material.
