Flex Seal Rubber Sealant Coating is a thick liquid spray that seeps into cracks, holes and gaps, then dries to form a watertight, flexible rubberized coating. It stops leaks fast and keeps working in extreme heat or cold, remaining pliable while it protects surfaces from corrosion, rust and water damage. This versatile sealant works on wood, metal, tile, concrete, masonry, fabric, glass, plastic, aluminum, porcelain, drywall and rubber.
The portable aerosol spray can makes application easy and fast—one pass covers quickly, unlike traditional spray paints. Once dry, the rubberized coating can be painted any color if desired. It adheres to both wet and dry surfaces and resists sagging or dripping in summer heat and cracking or peeling in winter cold. The sealant also deadens noise and vibrations while creating a durable, long-lasting barrier against weather and the elements.
