This mineral surface, non-skid finish provides a safe walking surface, while “peel and stick” technology allows for easy installation. Gard-Lock is specifically designed with adhesion promoters to provide better adhesion over a variety of temperature ranges. Apply to all roof areas that are prone to leaks.
