Flex Seal 1 gal. Clear Liquid Rubberized Coating

Flex Seal Liquid is a thick rubberized liquid that seeps into cracks and holes to seal out air, water, and moisture. Once applied, it dries to a watertight, flexible, rubberized coating that resists mildew, chemicals, and UV degradation while withstanding extreme weather conditions. Ideal for roof repair, foundation sealing, gutters, and weatherizing, this versatile sealant forms a durable, breathable, non-slip protective barrier on a wide variety of surfaces. It prevents rust and corrosion, is non-flammable, and is safe for use around plants and animals.
