J-B Weld 8277 WaterWeld Epoxy Putty Stick - 2 oz.

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.

Was delivered on time, but I’m giving it five stars.. had a leak under kitchen sink.. hasn’t even been 4 hours and I can tell.. it’s going to hold. It literally feels like a cast already. If it doesn’t work will update. A professional could have done better but as a single woman did my best .

This is going to be a positive review because the Off White color was appealing and I found the product easy to use, meeting my expectations. I used it to repair a cracked skimmer in our pool. The putty mixed up easily and the application was straightforward. The only hitch? The size and quantity. A mere 2 oz. stick and only one in a pack - a bit meager for the price if you ask me. It's early days, so time will tell how it holds up. Despite this, I'd still recommend it as a handy, quick fix!

Tiny crack on a brazz nozzle in the garage needed mending. It's an old school, solid brass part so replacement is expensive and it hooks up to a water hose in the garage so I didn't want to waste money. Bought this on a whim, followed the simple instructions, put a layer over the crack and voila....it's fixed and holding up nearly five months later. Wear disposable gloves when working with this. It's a bit of a pain to take off after contact with the skin.

Works great on my 350 gallon water hauler. I had a 3 inch Crack at the very bottom of my water tank. It leaked about 150 gallons a day. I used the JB water sealer, and it hasn't leaked a single drop. So far so good. Mind you, the Crack is at the very bottom of the tank, thats where 350 gallons of water weight/volume is, and it been about 3 weeks, ambient temperature here in Arizona is 110. Not a single drop. Definitely worth having around.

For some reason, I needed to put on several coats to stop a leak in water container, but I got it done! You need to really mix well as the center mix seems to be lacking and the mixing gets more on your fingers than where you will want to put it. I waited a day or longer between coats for it to fully dry before I water tested. It kept leaking ever so slightly finally got it on my last coating! I cleaned, sanded and cleaned again before applying epoxy...

It definitely hardens underwater, but I needed it to stick underwater to a plastic drain. It didn't seem to have enough stickiness to do so unfortunately, it just fell off in a big chunk.

Great product. Bought a sink from the habitat for humanity and it had holes drilled into it. Couldn't return the $200 sink, tried silicone multiple times and it continued to leak. Bought this, and was going to buy the stainless steel one if this failed, but its been holding great for months now, not a drop of water has leaked!!

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.

Déjalo de secar dos o tres días en entornos húmedos. Va de lujo.

Great product works on my hottub jets as they are expensive to replace and water weld works brilliantly.

Just what I needed
