Carlisle CCW-704 is a solvent-based, rubberized bitumen mastic. After evaporation of the solvent, the remaining compound is a rubber-like material that adheres tenaciously to the polyethylene facer of CCW Sheet Membranes
CCW-704 Mastic is used as a secondary seal on the seams, T-joints, overlaps, and other terminations/penetrations of CCW sheet membrane systems. It is designed for use on the top surface and edges of the CCW sheet membrane and should never be used underneath the membrane. Coverage rate ½" bead yields approximately 100 linear feet per gallon. Estimate one 30-oz. tube for T-joint and end lap treatment for every 200 sq. ft. of membrane installed.
