Cop-R-Tite Mastic

This unique fibrated mastic was developed to insure the proper sealing characteristics of asphalt based laminated copper flashings. Cop-R-Tite flashing mastic is a compounded composition of asphalt, mineral stabilizers, and interfibe. It is manufactured to a trowel grade consistency, which will provide a durable, elastic coating highly resistant to weathering while providing excellent adhesion properties. Cop-R-Tite Flashing Mastic performs well over a wide range of temperature and weather conditions.
