Karnak #405 Bond-N-Shield is a 100% elastomeric acrylic, co-polymer emulsion, specifically designed as a base coating that will provide excellent adhesion to asphalt surfaces. Technological advances in the Karnak laboratory also give this acrylic coating improved water blistering resistance in temporary ponding areas versus traditional acrylic coatings. The coating contains stain blockers that prevent asphalt bleed thru thus producing a brighter white coating over these surfaces.
