About Flex Paste, 1 lb Can, White, Waterproof Paintable Putty
62% liked its flexibility, but 38% found it too rigid
I have used flex paste to repair cracks and seal my fireplace flashing, and even painted over a sneaker cabinet covered with wall paper with clear flex seal, and it looks awesome.
I purchased this product to seal various surfaces in my home, indicating its flexibility in terms of sealing different surfaces.
I used a fine art paint brush to apply the paste on smaller areas and to smooth out the paste after using a spreader. This indicates that the product is flexible and can be applied with different tools.
I had to seal up a roof seam that was 8 feet long and got only 3 one pound tubs, which were not enough.
63% appreciated its moisture resistance, but 37% found it let water in
After applying the product and repainting the stairs, there was no more water leaking in.
This paste is a better option if you have respiratory issues or if ventilating the area is difficult.
After applying the product and repainting the stairs, I noticed no more water leaking in, indicating good moisture resistance.
The sealer has a soft spot in the middle and only about half of it is usable, indicating it may not be moisture resistant.
63% praised for its strong adhesive, while 37% found it didn't hold well
If you have respiratory issues or if ventilating the area is difficult, paste is a better option.
The outer layer of the hardware-sealer is rock hard.
I am disappointed with the product. It was a waste of money and I probably won't be buying it again.
61% appreciated its fast drying time, but 39% had to wait too long
About half of the product was unusable as it was dried up and hardened upon opening for the first time.
After a week or so, the hardware-sealer had completely dried out in the container even though I had placed the foil back on top as instructed.
64% found it easy to apply
It is very easy to apply and stops up holes. It has been a few weeks and there are no signs of breaking down.
It took two jars of the product to completely solve our water issue.
61% praised for its long shelf life, while 39% found it expired quickly
I noticed that the seller is selling old stock that is not up to the mark.
Half of the product was unusable as it was dried up and hardened upon opening for the first time.
