Flex Seal Flex Paste Max Rubberized Sealant, Black, 12 Lb Tub

Flex Paste Max is a super-thick rubberized paste that starts as a workable compound and dries to form a strong, flexible rubber coating. Designed to seal, fill and repair virtually any surface, it blocks out air, water and moisture while remaining permanently flexible. This all-purpose sealant clings instantly to surfaces and fills large gaps, cracks and holes without shrinking or washing away over time.

Whether you're repairing concrete foundations, sealing roof leaks, stopping rodent entry points, or addressing auto, boat and RV damage, Flex Paste Max delivers reliable, long-lasting results. It can be applied on dry or wet surfaces, and can even be applied underwater. Once cured, the flexible rubber coating can be painted any color to match your project.
