Swift 1 lb. Black Flex Paste Rubberized Adhesive

Flex Paste is a super thick rubberized paste that clings to surfaces and instantly fills large gaps, cracks, and holes. Once dry, it transforms into a strong, flexible, watertight, rubberized coating that seals out air, water, and moisture. The heavy-duty formula will not wash away and can even cure underwater. Ideal for interior and exterior applications, this paste is UV-resistant and mildew-resistant to protect projects from weather damage. It adheres to a wide variety of surfaces including wood, glass, tile, concrete, aluminum, brick, masonry, fabric, fiberglass, ceramic, and plastics, making it suitable for home repairs, gardening, crafts, and sealing leaks.
