  • For massive leaks and flooding, Flex Paste Max penetrates deep into large cracks and holes to stop leaks fast. Save more with our largest size ever, and get more coverage for your indoor and outdoor projects.Flex Paste is a super thick rubberized paste that clings to the surface and instantly fills large gaps, cracks, and holes. Once dry, Flex Paste turns into a strong, flexible, watertight, rubberized coating that seals out air, water, and moisture. Flex Paste is easy-to-use, making it a great option for crafts, hobbies, gardening, and all types of projects. Flex Paste can be applied on dry or wet surfaces and even underwater. It will not dissolve or wash away and even dries underwater. For best results apply a generous amount to the surface using firm pressure. This will help push the water out and allow better contact to the surface during application. Etching the surface may help with adhesion on both wet and dry surfaces.
