Description
MiraDri 704 is a solvent-base, rubberized bitumen mastic. After evaporation of the solvent, the remaining compound is a rubber-like material that adheres tenaciously to the polyethylene face of the sheet membrane.
Product Applications
MiraDri 704 Mastic is used as a secondary seal on the seams, T-joints, overlaps and other terminations/penetrations of sheet membrane systems. It is designed for use on the top surface and edges of the sheet membrane and should never be used underneath the membrane.
Coverage
A 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.
