J-B Weld Water Weld Epoxy Putty Stick - 2 oz. White

I used this to plug a dime-size hole in a plastic drain pipe. Let dry overnight just to be sure. Not a drop of water has leaked out since using this product three months ago. Just be sure to follow the directions carefully. I am a believer!

I have a $1200 instantaneous water heat that was fairly new and a PVC portion of the feedwater pipe inside the unit broke in freezing temperatures. The part was not replaceable and I didn't want to throw away a brand new water heater. I used JB weld on the interior fitting and JB PipeWeld on the exterior, and it works great--no leaks. Going on 1 month now with no problems.

I'm shocked at how well this worked. I just knew it was too good to be true. But it's been a couple of months now and it's holding strong! Placed around the drain in the tub where there was a chip. It's hard as the tub material, still! And what a price!

This is awesome stuff. Used successfully to plug pinhole crack on motorcycle coolant reservoir from rock damage. Surface prep and waiting 2-3 days to proper cure is crucial. Check and check again. Use coarse sandpaper after using degreasers and NO water or fluids when applying. Make sure it is mixed proper bc it is like working with fast drying cement when it is.

Tiny miracle, I used this to create a condensate catch pan under my air conditioner. I made the pan but needed a way to seal and permanently join the corners where the side meet up. This was simple to cut a small piece, kneed the material for a few seconds then press into the joint. After holding place for about 30 seconds it held strong. I let it sit over night and then tested water tightness, it worked flawlessly.

I used this to repair a crack in a plastic water trough. It was easy to do and is still holding up. I was skeptical that it would work at first. Very satisfied with how well it worked!

Easy to use. Works great. Used it to repair some fiberglass. The only thing I did not like is it seemed to stick to the vinyl gloves I was using to mix it.

It's super easy to use and just fills the gap—didn't hold my pool pipe pressure though. I'd probably return it, but I've already used up all the clay. It helped reduce the leak, but it didn't seal completely.

I've used JB Weld Water many times and find it to be a great product every time I needed it. Applying to woods, metal, pvc, tile and more. Its drying fast great for mold repairs and the easy sanding makes it the go to repair kit.

Sold as tank repair that is fully resistant to water and gasoline when hardened. I cleaned and sanded a plastic fuel tank, allowed to dry and 5 months later a large piece of the patch peeled off like it never had adhesion. The failed epoxy has the texture from my sanding lines, it was degreased before applying and there was no gas present.
