Flex Paste Super Thick Waterproof Rubberized Paste, Black, 3-lb. Tub

Flex Paste is a super thick rubberized paste that spreads, shapes, forms and seals virtually any surface. It starts as a thick paste and dries to a strong, flexible rubber coating that seals out air, water and moisture. Whether you're fixing cracks in foundation concrete, sealing gaps around windows, repairing roof damage, or blocking entry points for rodents and insects, Flex Paste clings instantly to fill large holes and gaps without shrinking or washing away.

This waterproof sealant works on both dry and wet surfaces, and can even be applied underwater. Once fully cured, the flexible coating accepts paint for a seamless finish on walls, decks and other surfaces. Its mildew-resistant properties keep the sealant clean and effective in damp environments, making it ideal for bathrooms, basements, outdoor projects and auto, boat or RV repairs.
