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.

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.

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.

Didn’t work. Followed all instructions and the paste didn’t take over just a slightly moist surface around a radiator valve. Left it bound with ptfe tape to help it take but it didn’t. The area is still weeping slightly. I will have to look for another way!

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...

Very expensive for a small product ……However it did the job but I could have done with more of the product to fully complete the job.

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.

My go-to epoxy for wet stuff. Lasts where others don't. Even repaired a cracked toilet cistern with it years ago and it's still going strong.

Good

I wish I could give this 6 stars. I had a small but annoying drip coming from my cast iron plumbing which is now over 50 years old. This was easy to apply. Just break off a small piece and knead. It sticks directly and cures very fast. Just spread it over the leaking area. So far it has been a few weeks and the leak is still dry. I see this as a permanent fix that will last a very long time. There is a slight odor but it goes away as it cures. The repair is not attractive to look at. Maybe a more seasoned veteran could make it look better but it is on a pipe in my basement and saved me hundreds.

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.

Works as advertised. Easy to use and waterproof.

Muy bien adhesivo para pegar tazas y cosas así excelente
