Recommended Application: Apply two coats of mastic at 12 mils each. The mastic should be brushed or worked with a rubber glove to allow the solvents to release. Work in a well ventilated area. Recommended eight hours as a minimum time until backfill.

Option: TC Reinforcing Scrim, a polyethylene wrap, can be applied over the mastic or between mastic layers, giving the coating added strength and impact resistance and acting as a secondary barrier if the mastic has not completely hardened prior to backfill.


Surface Preparation

Prior to coating application the surface should be clean, dry, free of oil, grease, rust, scale and loose coating.
