About this item
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.

Buy from Mfg for fresh product and low price
I purchased the flex paste to close open ends in my deck railing which is 1 1/2" pipe. your product was fresh and I used a butter knife to do the job. I was able to clean the knife and my hands afterward ...it worked perfectly and I still have some I am saving for any leaks that should arise.
Hi there, thank you so much for sharing your awesome experience with us! We're so happy to hear the Flex Paste was the perfect solution for your deck railing repair. If you ever need help with a future project or repair, you can email us at Humans@FlexSealProducts.com. Have a Flextastic day!

Flex Paste - Fixes Shower Tub/Leak
We've had an on-going problem with our 20 year old fiberglass/gelcoat shower/tub. The leak started as a small hairline crack in the bottom and has grown to 2-3". Over the last 3 years I've patched it twice with the Gelcoat Repair Kits which last a while, but begin leaking again. I did some research and decided to give Flex Paste a try. I covered the leaking area with Flex Paste and have been leak free for a couple of weeks. It seems like a solid repair and we'll see how long it lasts. I like that I can spread the Flex Paste well beyond the crack.
