Product Details
- 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. Our super thick formula will not wash away and will even cure underwater. Flex Paste is UV and mildew resistant and is perfect for all types of indoor and outdoor projects and repairs. Use Flex Paste to help prevent expensive damage from leaks. 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.Recommended Surfaces:Flex Paste clings to a wide variety of surfaces! Wood, glass, tile, concrete, aluminum, metal, brick, stucco, masonry, copper, fabric, fiberglass, ceramic, porcelain, natural stones, roofing, PVC, EIFS, EPDM, CSPE, Hypalon polyurethanes and so much more.
