A heavy-bodied all-weather trowel-grade mastic that contains select asphalts, petroleum solvents, tough reinforcing fibers and special additives that enhance spreadability.

Dries to form a durable but pliable seal that allows for minor expansion and contraction. Acid and alkali resistant, it bonds to all clean surfaces except coal tar-based materials. Available in winter and summer grades. 100% ASBESTOS FREE.

Ideal for flashing construction and other detail roofing work such as tie-offs or shingle securement. Provides excellent waterproofing properties for temporary repairs, or more permanent repairs when used with glass reinforcement.
