Flex Seal 1 gal. Gray Liquid Rubberized Coating

Flex Seal Liquid Rubberized Coating is a thick liquid that seeps into cracks and holes to seal out air, water, and moisture. It dries to a watertight, flexible rubberized coating that resists mildew, chemicals, and UV degradation while withstanding extreme weather conditions. Ideal for roof and gutter repair, foundation sealing, concrete and asphalt maintenance, and outdoor equipment protection, this coating creates a durable, non-slip protective barrier that prevents rust and corrosion.
