Product Details
- Flex Paste is perfect for DIY, Handyman projects, arts & crafts, hobbies and so much more! Use it to repair your roof, winterize your home, plumbing repairs, to seal cracks, automotive or marine repairs, pool and spa repairs, and so much more. One pound of Flex Paste provides about 10 linear ft at 2 inches wide with a layer thickness of approx. 1/16th inch. Flex Paste can be used on windows, doors, vents, thresholds and so much more. It will create a watertight barrier that seals out air and moisture. Use Flex Paste to help prevent flood damage. It can even be used to fill large voids to help keep insects and rodents out of your home. Unlike spackle or joint compound, Flex Paste dries to a waterproof, flexible rubber. Therefore, sanding may not be the best option once Flex Paste has cured. Instead of sanding we recommend using a putty knife, trowel or similar tool to smooth over the surface of the Flex Paste to your desired finish. You can even add designs and patterns to Flex Paste to create your own unique artistic textures. Flex Paste can be applied on dry or wet surfaces and even underwater. It won’t 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.

Flex Seal Flex Seal Editorial Review
Flex Seal, 3 lb Flex Paste Super Thick Rubberized Paste, White is a versatile industrial sealant designed to effectively fill gaps on various surfaces. Users appreciate its strong adhesion and quick setting time, generally within 15-30 minutes depending on conditions. While it provides a durable seal, customers have noted that the packaging could be improved, as some received tubs with solidified paste due to inadequate foil coverage. This product works well for sealing leaks, especially on outdoor items such as RVs and toy haulers, but it may require thorough cleanup after use due to its thick and sticky nature. Overall, it's lauded for its performance despite minor packaging issues.
