J-B Weld 8277 WaterWeld Epoxy Putty Stick - 2 oz., Off White

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

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.

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

. I’ve seen some negative reviews for this product But , if you FOLLOW the SIMPLE directions then you should be good. For systems under pressure you should relieve the pressure before you start the process. Rough the entire area with a file or wire brush then lightly sand before degreasing. Make sure all debris and dust are cleared, mix the putty VERY WELL. You will feel it getting warm, then apply. Wait about an hour or two before reintroducing pressure.Edit to add: check the bottom of the product for the silver disc that has the manufacturing date. The product is good up to 2 years after manufacture date. Example, my tube has 5093, that translates to, being made on the 93rd day of 2025.

I loved it. I bought it to stick some lights in my pool, and it worked perfectly. I feel like it stuck underwater. It can stick anything. I recommend it; it works super well.

Easy to use molds well to pipes and seals well. Stopped a leak in my water heater plumbing. Holds well.

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
