Flex SealPFSWHTR16-DS3PKS PFSWHTR16-DS-3PKS Flexseal, White

I bought this to fix a crack in a cement birdbath. As an old lady trying to go by the instructions I found it tricky to use. That’s my fault!! I got a good layer of it over the crack and in the bowl and in 48 hours I’ll know iif my birds will keep clean this summer!

This product is great. It is thick but went on the RV fiberglass cover nicely & filled a 1/2" x 3" gap & crack in RV rooftop corner.The container that I received has a 1/4" thick layer of solid paste inside the wall of the container...thus making this $30 container 1/2 useless. I need to drive 15 miles one way just to return it for refund. Buy from a different seller that has a fresh stock. I used it 24 hours after receipt & am disappointed that I am unable to use the rest of the paste for other projects.UPDATE:1 year later & repair is still holding. The white does not remain true white, & yellows a little with time & heat/sunlight. I would purchase this product again, but maybe NOT have it mailed to hot climates. Seller DID refund after return of unused portion.

The set-up is different. It is flexible when cured. So, to get a true flat finish you may need a clear wrap over the area for it to cure.

When I first opened the new Flex Seal paste jar only the very center of the jar's paste could be used. All the other paste was dried up and unusable. I used a little bit of the paste but it seemed dry as well because it did not apply smoothly. I covered the jar with the tin and closed the lid tightly after using the paste for 5 minutes. I opened the jar again 2 days later and now almost all of the remaining paste was dried out and unusable. The very small project I needed to was not completed due to the problems with the Flex Seal paste.

I bought and used it once. The paste itself is great but $20 for a can you only get one use out of is pretty expensive in my book. I love this stuff but I bought and used it once. Went to use it again and it was completely dried out. Followed there instructions to the letter to close it up and it still dried out. Won't order again. Will get a different container.

I had a large crack around my RV antenna that was leaking into my trailer. I filled the crack with this paste and it has not leaked a drop sense. Its easy to work with and dries pretty fast, i would definately use it again.

Excellent Product. A tree limb went through newly shingled garage roof. Not young people to be climbing on the roofs, I patched the hole- size of golf ball, from the inside of the garage. Rain came the next day-- product holds great! easy to apply, handy tools are sent with it. Would certainly recommend this-- and if need again, will start w/this product!

Very Disappointing and time consuming. I carefully followed each direction, and was able to slow the leak but not completely seal the fountain dish. I noticed a spot that had lifted and found the dried flex paste was easily removed and water had seeped under the FLEX PASTE! UGGG. I went to apply more flex paste, but it was solid within the jar! (I also sealed the jar as directed) I will be returning all FLEX SEAL PRODUCTS. !
