About Flex Seal, 14 oz, 2-Pack, Gray, Stop Leaks Instantly
Overall Feedback:
80% positive
78% praised for its strong adhesive, while 22% found it didn't hold well
I found the product easy to apply and there were no further leaks. The adhesive strength seems good.
The product leaked through all the seams the next day, indicating poor adhesive strength.
77% found it easy to apply
I found the product easy to apply and it resolved the issue of leakage.
64% appreciated its fast drying time, but 36% had to wait too long
I used two cans of hardware-sealers and they dried with a fine sandpaper like finish.
83% liked its flexibility, but 17% found it too rigid
I used the hardware-sealer to cover the seams on a wood deck box.
I am disappointed with the new cans of Flex Seal. They dry with a fine sandpaper-like finish, which is a significant departure from the smooth, rubber-like finish of previous cans. I wonder if the product is fake or if the formula has been changed for the worse.
