J-B Weld 8277 Waterweld, Multi Color, MULTI-COLOR

I needed to repair a crack in a drain line from the grey tank in my RV Travel Trailer. My crack was half the circumference of a 1-1/2 inch PVC pipe at a 90 degree fitting. I was a bit skeptical of the product after reading a few reviews saying the material was hard to mix and either didn't dry or didn't stick. But I decided to give it a try. I cleaned and rough sanded the connection per the product instruction. I found it very easy to mix together the two materials into an even mix. It took about two minutes. (Wear latex gloves - you will thank me!) I then applied it completely around the pipe and fitting. It stuck very well and was well set up about 20 minutes later. I waited a few hours before filling water in the tank and line. No leak whatsoever. I took the trailer on a 4 day camping trip along with 180 miles of driving. (I was curious to see if it would hold up to the road vibration.) It stayed bone dry. For me, the product was a huge success and saved me from having to cut out several sections of pipe and fittings and have to replace them.

I needed this product to seal a tiny pinhole leak in a pipe; I'm not able to shut off the water, so it needed to be good on a wet surface. Well, this wasn't. It wouldn't stick to the wet pipe surface, so I molded it in a ring around the pipe so it could stick to itself. I kind of worked, but even the tiny amount of low pressure from the dripping pinhole was too much for it; it failed completely before it hardened, despite my best efforts to hold it stable.Not a great product at all for this application. Maybe on a dry surface it would set properly and then be waterproof. Part on the problem is that it takes way to long to harden, and there's no way to alter hardening time.

This product is a must on pool tears ..I had never heard of it..I used Flex allPool patchesNothing workedThe pool i purchased had portholes for looks only ..The coleman poolMany other customers are experiencing the same problem..I googled this problem..And this product came up ..Dont hesitate..If you are experiencing pool leaking

I tried to do a temporary repair on a kitchen faucet. There is a pin hole in the neck of the faucet allowing water to spray and also run down the neck to the sink deck.I waited a long time after applying and the first time I turned on the faucet, the water leaked exactly the same as before. The only difference is that now it only runs down the faucet instead of spraying. I could have accomplished that with a bandaid.I would not recommend this product

I thought this stuff would be awesome for a shower since it is used for boats and stuff. Even after like 24 to 48 hours this product didn't dry all the way and to boot when it got wet it started to bunch up into like clumps. I got rid of it and used some Gorilla caulk instead which did the trick.
