J-B Weld WaterWeld, 1 Hour Cure, Epoxy Putty Stick - 2 Pack, Off-White (8277-2)

I was desperate. I live in an old house with old pipes. One had burst open at a joint and I could not get it to stop spewing water. I was told it would be the next day when the plumber could come out. So I tried wrapping it with waterproof tape and I made an order for the weld. Having gotten it I tried my best to apply it to the pipe, over the wrap, and any other open place I could put it. I finally got it down to a drip. Now here's the thing, when the plumber did get here he tried everything he could to remove that mess that I had made. He finally had to saw off that piece of the pipe and replace it. He shook his head at me and told me there was no way that piece of pipe was going to be uncovered. Whatever I had put on it had solidified and was not coming off. So here's my thought, had I been able to get the pipe dry and apply it as per instructions it would have held. I just had a problem would not being able to find the shut-off. So I had the plumber show it to me before he left, not knowing that having done that he may have just knocked himself out of that next call! LOL

Used this to fix a small leak, and so far it’s holding up great. I cut off a small piece with a tool, mixed it by hand (definitely wear gloves), then pressed it onto the area. I applied it around 10 PM and waited until the next morning before turning the water back on.The putty was easy to work with and hardened nicely overnight. Just make sure to knead it thoroughly until the color is uniform before applying. Overall, very handy to have around for quick emergency fixes.

I’ve purchased twice now. I can’t remember what specifically we needed it for but I think it was a fridge filter situation because I remember wanting something that is drinking water safe. I think we used it on a leaking sump pump pipe too, but ending up needing a new tunnel dug anyway.This time around, I just needed some sort of underwater glue for a hot tub headrest. Needed something that can handle water some heat and won’t get messy with pipes chemicalsIs a little tricky to use. Didn’t come out as perfectly smooth or flat as hoped but seems to hold well. I wasn’t concerned with appearance

Got this for leaks in my pool liner. Just mix it well and apply. I had several holes in my pool liner (old liner) ripped a one inch hole removing a liner patch that wasn’t sealing well and sealed it right up with this stuff. Works very very well and drys rock hard, even at the bottom of my pool. This product will cure under water! No more leaks!

Arrived on time and in good condition. This stuff works very well and dries quickly. Super-hold and a good item to keep around for emergency repairs of most anything. We keep one in the RV and one on the boat. Great stuff and highly recommend.

Amazing, helped seal a crack in a very old pipe until I can have it replaced. Make sure you mix well and 'smooth' the edges down so there are no gaps for moisture to leak. Very easy to use, very affordable and so far is holding up very well. It is putty, so make sure your gloves are a little more fitted to make kneading easier.

Why did you pick this product vs others?:I needed to attach a bracket underwater to the wall of my pool. I thought that this product would work. It didn’t. This product will fill in a hole, but will not attach a free standing piece. It will stop a leak, or fill in a crack.

Counless uses.Still worth always having around despite the fact that the price has gone up so much since the Bonham family sold the company to private investors
