Review: Good
Review: Exactly what I needed. My kitchen sink has a little C-clamp piece that holds the pull-down faucet hose, and it kept slipping off — once it fell straight into the garbage disposal while the disposal was running 😳. Of course the sink model is discontinued, so replacing the part wasn’t happening. This WaterWeld putty was the perfect solution because it’s moldable (like Play-Doh), gap-filling, and made for wet environments. I dried the area, wiped it down to remove grime and oils, then cut off a small piece and kneaded it until the color was uniform (took about a minute). You don’t get a ton of working time, but it was easy to press into place and shape. Pro tip: use gloves, and rough up the area firsst. It started firming up quickly and cured fast enough that I felt comfortable using the faucet again later the same day. It’s now holding the clamp solidly and I’m no longer living in fear of the “garbage disposal snack attack.” Only downside: the working time is short, so have everything ready before you start. Otherwise, this did exactly what it promised and saved me from replacing a whole fixture. ⭐️⭐️⭐️⭐️⭐️

## Questions & Answers

**Q: bathtub**
A: You need two of them, an outside meadow, a sunset, and some ED medication.   Not sure how you'd use this putty so I won't ask.

**Q: does it work to fix pool leaks?**
A: I bought this as a last ditch effort to fix my pool. The one i already had to replace 2 pump motors and a whole pump assembly on. It was a $200 pop up intex pool from Wal-Mart. I had to patch it once this season but did so with it empty and used a pool patch kit and a crap ton of gorilla tape as insurance. So imagine my horror when i went to shock the "dark green pool" (as the kids described) that the kids won't leave the pump plugged into and see it low. 

Find it leaking and get out that handy gorilla tape. Wasted a whole freaking roll. Still leaking. Its 195 billion degrees in the Midwest and the kids won't leave my doors shut so the pool was how to cool down.

I grabbed this stuff and played with the putty on the way home (per instructions you gotta work with it first) went and shoved a bit into the hole. Fail. Added more.... Somewhat stopped. Still leaking. So i shoved about the size of a quarter into that small hole... Tons on top....

30 minutes later.... Success. For now at least.

Now to see if it withstands more water pressure and a bottle of chlorine for the green pool. Wonder if this will work to keep the power plugs together and running so the kids can't torn off the pump again.

This works beyond great.... Just don't skimp on the amount. The pool is hitting the trash this year.... So i won't know if this works long term... Im just looking for another 7 weeks.

**Q: Will it stick to something already wet?**
A: Yes. I used it to seal a gap between the plastic of my pool skimmer and the grout and tile of my pool lining--all underwater. It worked great and is still working many months later.

**Q: I have leaking pvc that is wet. Will this work on the wet pipe joint?**
A: Yes, it should. Make sure you cut section off with the outer & inner layer of JB Weld & thoroughly blend it together with finger tips.
Rough up entire surface you plan on applying epoxy to with sand cloth/paper so it can adhere to material which it is being applied to. If it spraying water under pressure, you need to turn water off otherwise it will travel under neath putty and escape. Turn water off, clean and sand area, apply putty wait a good hour feel putty should be nice and hard, if so turn water back on. This stuff is amazing, I have used it on 8"-10" PVC leaks at fittings but not under ant type of pressure, it was for a greenhouse cooling system,  I have used it on my bath tub to seal a 1" hole my son punctured with toy in tub. I have used it on natural gas, galvanized pipe to plug hole in pipe. Prep the area clean and sand most important,  doesn't take much putty. My bath tub I did two applications, did first let cure then sand the cured putty and just onto fiberglass of tub again to Rough up give putty something to bond to. I wait a good hour before I test. It's holding like a full on CHAMP from a good 5 years ago. It's good strong stuff, I recommend strongly to my fellow plumbers!

*by H***� on August 29, 2025*

Ich habe den J-B WaterWeld Epoxyd-Kitt für meine Pool-Filteranlage benutzt, weil am Deckel ein Riss war und ständig Wasser austrat. Obwohl die Anleitung nicht auf Deutsch ist, war die Anwendung absolut selbsterklärend: Stück abschneiden, kneten, auftragen – fertig. Meine Erfahrung: Sehr einfache Anwendung, man braucht kein Vorwissen. Nach dem Aushärten absolut dicht – 100 % erfüllt, was ich mir erhofft habe. Ideal für Notfälle im Pool- oder Sanitärbereich. Wichtig zu wissen: Das Ergebnis sieht nicht unbedingt schön aus, eher wie ein grober Flicken. Wer Wert auf Optik legt, sollte das bedenken. Handschuhe sind Pflicht – das Material klebt stark und ist schwer von den Händen zu bekommen. Fazit: Der Kitt macht genau das, was er soll: abdichten. Für mich hat er ein teures Ersatzteil gespart. Klare Empfehlung für alle, die schnell und zuverlässig etwas reparieren wollen.
