Customer Reviews for J-B Weld 2 oz. Waterweld Epoxy

Purchased to make a repair in a sewage ejector pit. It did not work even after following instructions.

This is easy to knead and clean up but not as strong as I had hoped. And it has to be kneaded thoroughly or it will have soft spots. The working time is adequate so that's a plus. Is it good for forming into tight spaces though because of it's softer consistency.

I don't have a clue if this stuff is going to help, but I know for a fact alot of these reviews were written by a professional review written haha

I bought three tubes of JB Waterworld I was sure it’s gonna work. I had three drips different sections of a pipe and it didn’t work. Very disappointed. I read reviews on this product from other people and they weren’t good. I’m gonna try and get my money back.

The glue was mixed together to work and that was easy

Great adhesive, compact, and easy to use. I would buy it again

Used this in a last ditch effort to repair a jetted tub that I was told was unrepairable. Cured in one hour and after 5 uses there is still no leak. I also used this to repair my hot tub 3 years ago and it's still holding. Not suggesting this is a direct replacement for getting something properly repaired, but it sure does seem to get the job done.

[This review was collected as part of a promotion.] This epoxy is an amazing product to use when you need to repair or plug a hole that will be in contact with water. I have used this product in the bathroom and outside. It holds strong! I would recommend this product as it really gets the job done.

The product is completely useless on pipes that have water running through them. I let it set on a cracked copper pipe for two hours before running water through it. Puddy fell off in a clump once it was exposed to water.

I had a leak in a coolant pipe between two radiator hoses used it and did a great job. Held pressure and dealt with the temperature also

Wonderful treatment was helpful identifying missing items.

Works but didn't like having to knead it. Would rather it come in a thick mixable form to more clearly tell when it is properly mixed.

Did not work as advertised

I had a small crack in the shower floor pan. I applied J B Weld per the instructions. I allowed it to sit for 24 hours even though the required time was less. The epoxy has held up tight so far despite getting wet from daily showers. Recommended purchase.

Works great for small fixes around pool and plumbing. Easy to use does the job

Absolute GARBAGE! I followed the directions regarding cleaning and prepping the pipe wit sandpaper...mind you the PVC pipe I was trying to seal had a small pinhole leak at the joint with a 90 degree elbow. I shut off the water supply and all that was left from the leak was a minor drip. This stuff would not even stop the drip! Every time I tried to apply the putty, the drip would come right through! After several attempts, I just gave up...even after it hardened, the drip was still there...don't waste your money...do it right and replace the pipe.

I honestly didn't have much faith that this product would work. I used it to repair a crack in a PVC drain elbow - it was very easy to apply & worked great!!!!

First, a qualifier: I have used other JB WELD epoxies with spectacular and long-lasting results. I recently had a toilet water supply valve corrode and replaced it. Unfortunately, the galvanized steel threaded connection broke off, leaving me with just enough threads to screw the valve on. There was still a slow leak. I used JB Weld Water Weld in an attempt to stop the drip with no success. On pressurized lines this is not a solution, drain lines may yield different results.

I was able to seal up a dripping leak in a PVC DWV pipe that was in too tight of a location to cut and replace. Very pleased with the results. And knowing it cures in the presence of water is extra piece of mind.

Poor bonding/sticking Hard to mix

Excellent product, works well

Did not work for me, trying to temporarily patch a pinhole leak in a supply line

Bought this a month ago. Used it to patch my fuel tank on my sonoma truck. Also used it, where my exhaust gasket was missing to quite my truck down. Worked great!

I have a residential leaking copper pipe with a small fishmouth leak opening. I have been applying layer upon layer. I wait 24 hours. I still end up having a leak at the edges of the layer last applied layer. I think I am following the directions. Not sure this stuff really works. Maybe for low pressure applications its fine. This sure has caused me a lot of grief.

I use for miner leaks and works great for reinstalling pool or shower tiles
