Flex Seal - Black 14 oz. Aerosol Liquid Rubber Sealant Coating Spray Paint

Flex Seal is a convenient rubberized coating that transforms from a liquid aerosol spray to a flexible, watertight sealant. It effectively penetrates cracks and holes, sealing out water, air, and moisture while preventing rust and corrosion. Once dried, Flex Seal remains flexible and durable, suitable for use on both wet and dry surfaces. It maintains its integrity in various weather conditions—resisting sagging in summer heat and avoiding cracking or peeling in winter cold. Additionally, it reduces vibrations and noise, offering surface protection from corrosion. Once fully cured, Flex Seal can be painted over in any color. It is versatile, working on materials such as aluminum, porcelain, drywall, and cement, making it a portable solution akin to having a handyman in a can, as Phil Swift says.
