Flex Paste, Waterproof Paintable Putty, Spackle Sealant, Fill Gaps Cracks Holes - Block Out Water and Air - UV Resistant - Walls, Drywall, EPDM, Concrete, Roof, RV Repairs, White, Cartridge

Flex seal is a great product. I use it to repair cracks in my stucco outside. Once covered, it does not cracks again. You still need to paint over it because with the clear you can still see the cracks even though they are sealed.

I liked the consistency of the putty. Easy to apply and set up in a time factor that allowed me to work the putty

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.

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

Did it’s job just as advertised.

Amazon's web page shows the "NEW! Stay Fresh Container", but they shipped the old obsolete plastic tub. As many of the other reviewers have correctly stated, the plastic tub cannot keep the product soft, pliable and usable. I called the FlexSeal factory, and they are fully aware of the problem. If you order from the FlexSeal website, the factory is shipping the Stay Fresh can as of 2024, March 12.This is a good product, but it's a complete waste of money to buy it in the obsolete plastic tub. That form of packaging is incapable of keeping the product in usable form. It hardens from the top down. I bought two from local stores, and learned that if you squeeze the tub at the top and it doesn't feel soft, the product has hardened and won't be usable. Typically it will be softer near the bottom, but all of the product above (the unsqueezable part) is so hard you can't get it onto the putty knife. Amazon needs to stop shipping the product in the obsolete plastic tub.Update: I called Amazon Customer Service and advised them that the plastic tub packaging is obsolete and no longer being shipped by the factory, and that they should return all product in the plastic tubs, and ship only the product (in the can) shown on the web page. I was advised that they would do so. That was on March 16, the same day I ordered the new (can) packaging directly from the factory. It arrives today (March 20). Shipping was free. Looking forward to seeing how it performs in patching a stucco parapet wall.Update: I received the can from the factory. The product was fresh and easy to apply. Because I was applying it on stucco, it took more to fill all the nooks and crannies than I expected, so I will need another can to finish the job. I ended up doing the whole job with a putty knife. I applied it in full sunlight on a warm breezy day, but it stayed flexible enough to work it into a smooth surface as I went. I doubt it will need a second coat. I don't know how long it will last, but I expect it will be pretty durable. There is no way any rain is going to get through the FlexPaste. I used a rubber spatula to scrape all the product from the sides and bottom of the can. Clean-up was easy; I just wiped the material off the tools with paper towels.

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!
