Polyprene^®

Heavily plasticized and fibered all rubber Polyprene makes repairs and can’t get brittle because it contains no bitumen or other vulnerable compounds. Versatile and easily installed between laps or anywhere that repair is required. Perfect where materials of differing coefficients meet and total flexibility is required. Replaces ordinary asphaltic cements with approximately 5x the strength and 10x the elongation. The unusual compound that provides a very high solid content also results in very minimal shrinkage and a high build at areas where a durable seal is typically needed most. Available both in heavy brush grade for general use, trowel grade for areas where a stiffer cement is required, and caulk cartridges for those difficult to get to areas. Applies quickly and easily with a stiff brush or rubber glove in one layer without threat of mud cracking. Ready to use with no mixing. Will not dry out or become brittle at cold temperature extremes. Use in conjunction with PolyCore™ reinforcing membrane where added reinforcement is needed.
