Flex Seal 1 gal. Black Rubberized Coating

Flex Seal 1 gal. Black Rubberized Coating is a versatile liquid sealant that seeps into cracks and holes to effectively block out air, water, and moisture. Once applied, it dries to a watertight, flexible rubberized barrier that prevents rust and corrosion while standing up to natural weathering. Ideal for a wide range of indoor and outdoor applications, this protective coating resists rain, snow, sun, wind, hail, UV degradation, and extreme temperatures. It creates a durable, breathable, and non-slip surface suitable for roofs, foundations, gutters, RVs, and everyday maintenance projects.
