Great stuff, very easy to apply like a butter, in a couple of minutes job done. I used it over multiple areas inside the attic to stop roof leaks after recent heavy rain. I saved hundreds of dollars and wasting time with roofing companies.

This stuff is very stiff. At first I thought the can leaked and it dried out. It didn't, it's supposed to be that way! Apply with a putty knife. Doesn't run at all. Dries perfectly. I love it!

Calking is fine. I wish I got the tube with the calking gun included. It is much easier to apply!

UPDATE - I have been monitoring the pipe for the last few days. While I initially thought the paste was going to provide the fix I needed, that "thought" would be incorrect. The water started leaking again. Be smart/save your money and do not buy this stuff. I'm going back to what I should have done to start with - turn off the water and replace the pipe. This Flex Paste is JUNK!!!!Had a very small leak at the base of this water faucet (small droplets of water on the PVC surface). Based on the advertisement I thought the paste would be the perfect fix. I followed the directions as stated on the container. After apply a good initial coat, I still had the small leak. The next day, I applied another coat - still had the leak. The next day, after turning off the water to everything, I applied another coat heavy/massive amount of paste using both a putty knife and my hand. Left the water off for 1 to 2 hours and the leak appears to have stopped (after using most of the paste). What a pain!!!While using the paste, I was diligent in keeping the lid on the paste. At the end of each day, I would use a rubber mallet to hammer the lid on. Regardless of the tight seal, the paste still hardened.Probably would have been easier to just replace the bad piece of PVC that was leaking.

Works as the commercials promise keep on hand in every household !!

I applied this to a sanded/cleaned fiberglass crack. Let sit for 2-3 days then refilled with water. After about 4 months it began to break down.

Laughed at Phil swift commercials…. Stopped laughing when it worked

This stuff works great. Used it to seal some cracks in a basement wall where I had water coming in. The only thing I didn’t like is the can it’s put in. It’s hard getting out the material because of the lip for the lid. Previous version I used was in a plastic container and it was much easier to remove the material from the container. Otherwise this stuff works really well.
