Description
SEAL IT Dry Formula is a natural mineral that swells on contact with water to form an instant waterproof seal over leaking roof areas. Simply pour the material over the suspected leaking area, even through standing water and in temperatures as low as 20ºF. SEAL IT Dry will automatically flow to the source of the leak and plug it for up to six months, or until permanent repairs can be made. Use this non-polluting, fireproof patch material on any flat roof.
Coverage: 25 lb. unit covers 40-50 sq. ft. with a ½” layer
