About this item

Flex Paste Super Thick Rubber Paste is an ultra-thick, rubberized paste that you can spread, shape, and form to seal virtually everything. It starts out as a thick paste and dries to a strong, flexible rubber coating that can be applied to all types of surfaces to seal out air, water, and moisture. It clings to the surface and instantly fills large gaps, cracks, and holes. It won't shrink or wash away and can be painted any color. It applies on dry or wet surfaces, even underwater. Use Flex Paste for fixing cracks and holes, foundation and concrete repair, sealing out rodents and pests, bath and shower repair, roof repair, RV and motorhome repair, auto repairs, boat repair, lawn and garden projects, and countless more indoor and outdoor projects.
