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.

truthful and fair , I feel it was a Fabulous Fast
It was easy to put a new non-skid sole on my favorite tennis/work shoes. Product uses and directions explained well, and it did do what it was supposed to. Needs to come with application tools and clean up resource.

It worked...
Despite the top half of the container being dried out and totally useless because the foil was not properly inserted by the manufacturer, I managed to get enough of the product for the job I needed it for, and it worked, SO, I am glad I swore at it and pried the chunk out and used it rather than get a refund, which in a weird way makes me a happy customer ONLY bc it worked.
Hi Richard, thank you for your feedback. We're glad to hear that the Flex Paste worked for your project. When you have a moment, please message us Humans@FlexSealProducts.com so we can investigate the issue with your Flex Paste further. We look forward to hearing from you, have a great day.

Sticks to everything
The tub is actually small. On TV it looks large. The product works great and it sticks to just about anything. The tub arrives with a foil covering or should i say partially covering the paste. The product not covered will have solidified. I estimate that i lost 25% of the product because of this. Maybe someone should check when they are making the product that the foil needs to COMPLETELY cover the product
Woah, thank you so much for getting back to us with a 5-star review! We'd love to know more about your project and how you used Flex Paste so please message us through Humans@flexsealproducts.com. We look forward to hearing back from you.
