Flex Seal

Leaks, cracks, and gaps have a way of showing up at the worst time — on a roof, a gutter, a pond liner, or an outbuilding wall. The Flex Seal line tackles those situations with rubberized waterproof formulas in spray, liquid, tape, paste, and glue formats, so you can match the product to the job rather than forcing a workaround. Gorilla also offers a rubberized patch and seal spray that fits right alongside. Color and surface type matter when choosing — clear, white, and black options are available, and some formulas bond better to certain materials than others.
