JB Weld Jb8277 Waterweld Under Water Adhesives, Off White 2 oz, 1 Pack

I used this on my stainless steel hot water cylinder 2 months ago as a temporary fix and so far so good is still holding. My cylinder is a on a sealed system with 2 bar pressure. I discovered a leak in good time before any damage to my timber floors. Waiting for a plumber just took too long and so I decided to do a temporary repair myself. I located a pinhole leak which was squirting the water out a distance under pressure. The foam insulation around the tank meant I had to do a bit of insulation removal to find the leak location. I drained the cylinder tank, dried around the area and used the JB Waterweld to repair the hole. I used latex gloves which, while very sticky with the epoxy putty, is better than bare hands with sweat/hand moisture etc which I felt could prevent the epoxy from adhering properly. I used about half the epoxy putty and worked it into the pinhole as much as was possible and then covered a big patch around the area but not too thick. I tried to remove a small bit of the dried epoxy putty recently to see how well it was sticking but it was completely ’welded’ to the tank. Obviously the most important thing is to make sure that both parts of the putty is completely mixed together to form the off white colour before use. I probably will need to get a new cylinder tank in the near future but everything is back working ok at the moment.

Good bond to my waterbut. Needed to seal the input drain pipe that was leaking. Fixed it with this. No leaks, does need a bit of working to get it right and takes a good while to cure. But decent product overall.

Great product and far cheaper than a plumber to make an easy repair. I used disposable gloves (not supplied) to cut off a piece of the putty and manipulate into a dough like consistency before wrapping over the leak. Almost instant impact on the repair.

Bought to secure underwater - wouldn't adhere to a wet surface at all - very disappointing especially at this price.

Bought this to repair a cracked external 90 degree drain pipe. Easy to use...just cut of the amount required & mould together on you fingers. I recommend wearing some protective plastic / rubber / silicone gloves as this suff stick to you like a limpet... Easy to mould and apply but be quick...once mixed you can actually feel it starting to set as you use it. Full Setting time is dependent on temperature but mine went hard within 15 minutes at 15C. Once set, it is never goes 100% solid like some other epoxy products so keeps a bit of flexibility (95%) and doesn't go brittle. I've also found it useful for filling oversized holes in various materials and re-drilling for screws and rawplugs. Highly recommend this product if you have a water pipe needing some long term or temporary repair and more...it works...

Not impressed with this product. It is not difficult to use but I would only recommend for very small, dry leaking points. Applying to larger leaking/wet areas does not work well in my experience, even though it says it sets under water.

This worked very well at sealing a crack in the white plastic waste pipe from my gas boiler, it was dripping constantly, it can be a bit messy, next time I will wear gloves.

It actually did a great job.

Good

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. ⭐️⭐️⭐️⭐️⭐️

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.

Muy bien adhesivo para pegar tazas y cosas así excelente
