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
**Editorial Review of Flex Seal Paste** Flex Seal Paste has been well-received by customers for its effectiveness in sealing leaks and providing reliable repairs for various applications. Users have shared positive experiences using the product in a range of situations, from fixing leaky skylights and shower tubs to sealing ends of deck railings and roofs. Many praised its thick, spreadable Consistency, which allows for ease of application and flexibility in coverage. Customers found that Flex Seal Paste performs as promised, sealing leaks and holding steady even through severe weather conditions. A notable highlight includes its ability to perform effectively on previously problematic areas, showcasing its potential as a long-term solution for some household repairs. Some reviewers even expressed intent to purchase additional quantities for further projects, attesting to their trust in the product's reliability. However, there were concerns raised about the product's packaging and the lifespan once opened. Several users noted that once the container is opened, the paste starts to harden quickly, limiting the time available for application. Reports of receiving old inventory were also noted, where hardened portions rendered parts of the product unusable. This has led to a sense of caution among customers regarding the purchase of Flex Seal Paste, as the cost may seem high Considering potential waste. Overall, while the effectiveness of Flex Seal Paste is evident through multiple positive testimonials, potential buyers should be aware of the importance of purchasing fresh stocks and managing the product's application time frame post-opening. **
