Customer Questions & Answers

Does this work on ceramic/porcelain sinks?

We have a leak in a new 30 in x 18 in ceramic sink top that we have just installed DIY. The sink is ceramic/porcelain, and we've already attached to the vanity with adhesive, hooked up plumbing, faucet, drain, and all. Looks great. Yet when we turned the water on, we discovered a hairline defect about an inch long in the underside of the sink in the overflow trap area; it is dripping water from there. We don't want to undo everything and pry the sink up and take it back unless we really need to. Someone suggested using silicone caulking after we wait a day or so for it all to dry, and then waiting another day for it to cure and dry. But we want something really tough and that will repair the leak for years to come and we though of JB Weld epoxy. Ideally, we could get to using the sink sooner, too. We've used JB Weld products in the past and had great success in many different applications, but not on ceramic sinks. My question: Would this product be expected to work well in this situation, bond to the unglazed ceramic underparts, and last? If so, any recommendations for application, and waiting time before trying the sink again? Thanks!

I would not use this product on leaks. See my review.

Can this seal a leaky angle stop?

An angle stop under my kitchen sink is slowly (and occasionally) leaking. I'm reluctant to replace the angle stop since it is connected to a brittle looking galvanized metal pipe. Could this work if I smothered the leak area with it?
Asked by: Tom
It probably would seal the leak but it sounds like the valve is in the process of failing and the Water Weld would just be a band aid. It probably would be best to replace the valve, maybe have a plumber handle it. If that valve fails it could do a lot of damage.

Do i have to mix this with anything to make it work

Asked by: Jr
No, there are two parts to this stuff in a roll. You just cut a section off and knead it very well and it is ready to go.

Waterweld is rated 3.4 out of 5 by 35.

While replacing a bath sink drain I found the corian basin was chipped where the mack gasket is supposed to seal. I was a little skeptical whether this product would work and not possibly be porous. After cleaning the area of dust and dirt I packed the gap as tightly as possible. The product says it cures in one hour but I let it sit overnight. The following day, I sanded it smooth and installed the new drain. This repaired a basin that otherwise might have had to be replaced. * The directions say to wear gloves but the putty is pretty sticky so its far easier to work it with bare hands.

A hot tub diverter valve was leaking around the handle. The source of the leak was a failing PVC glue joint between the PVC feed pipe and the diverter valve assembly. Unscrewing the valve cap and removing the valve assembly gave me access to the leaking joint from the inside of the pipe. I dried and sanded the inside of the pipe at the joint and put a thin layer of Water Weld covering the joint on the inside of the pipe. Only a thin layer would allow clearance for the diverter assembly to be reinstalled into the pipe. After allowing the putty to dry thoroughly I reinstalled the diverter back into the PVC pipe and tested the assembly under pressure. The leak was eliminated and after several weeks and many hot tub operations it remains sealed.

I wondered why this product got such a low rating when I've used it successfully for small repairs in the past. Now I know. Part of my kitchen sink's iron drain pipe rotted out and I spliced in a new piece of pipe and used JB Water Weld to connect the two ends of the new pipe to the existing pipe. The epoxy held the pieces together like a rock but leaked at the joints. Each time I found a leak I had to grind off the epoxy and re-apply. Each time there would be another leak at a different place. This happened over and over again and I ended up going through 4 sticks plus my original stick that I had left over from previous projects. After all that, I think I finally got enough of this goop on the joint to where it's not leaking anymore but I don't know how long that's going to last.

Rated 1 out of 5 by from Quick Fix? a waste of money If you have a leak in a pipe...cut it, drain it and use an expandable union. This stuff adheres to your fingers but not PVC pipe.

Normally I'd fix the pipe, but the Pinhole is before the water shutoff valve. What does that mean? That means I would have to drain at least 1 o f the Hot water tanks. This is a tank that holds 2644 Gallons of 180 degree hot water and we have 2 of them. That's a lot of waste of not only water but the gas used to heat all that water. So I am trying a patch job. There is no way this stuff would ever have a chance or sticking on and staying under the pressure of the water shooting out of the hole. So using some of this stuff plus some stretch & Seal Silicone Tape, wrapped around the pipe tightly to hold this J-B Weld in place, still leaking, and a couple hose clamps tighten down on top, I've stopped the leak 100% for now. Which is much better then the last time I tried it with just the tape and clamps. How long will this hold up? Will this stuff harden up? I'll order up the parts I need to fix it correctly and get it fixed at some point, but only when I can completely turn off the water and drain the tank. I had better results then last time using this stuff also, so I consider it a win.
