Flex Seal is a rubberized sealant spray coating that sprays out as a liquid, seeps into cracks and holes, and dries to a watertight, flexible coating. It stops leaks fast and is ideal for sealing and protecting surfaces throughout your home and outdoor structures. Whether you're dealing with roof leaks, gutter damage, foundation cracks, or weatherproofing needs, Flex Seal provides a durable, flexible solution that adapts to temperature changes and prevents water infiltration.
This all-purpose aerosol sealant works on virtually any surface, including wood, metal, tile, concrete, masonry, fabric, glass, plastic, aluminum, and dry wall. Once fully cured, the flexible rubberized coating can be painted over to match surrounding surfaces, making it both functional and cosmetically seamless.
