WaterWeld Epoxy Putty Stick

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.

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.

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!

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.

I used this to seal around a pipe where it enters the concrete slab a plant was growing in it. I used it to help keep water, insects, and debris out. It was easy to apply, adhered well, and cured nicely. The finished result looks clean and has held up great so far. It did exactly what I bought it for. I would definitely purchase it again for similar projects around the house.

Purchased this to try to seal off a leaking PVC joint (1.5" ) on the return side of my pool equipment. I had low hopes as I've also tried a different brand of two part epoxy, but with the good reviews, thought maybe this was a superior product. After kneading it together, I applied it to the joint, completely surrounding the circumference of the joint and firmly pressing it in. Note that the joint (outside) was dry at the time. I let it cure for about 8 hrs (PHX, temp between 60-80 F during that time), and it was pretty thick as I used the entire tube, and was more of a brighter white (than off white). I pressed on the epoxy and it was "crusty" but still a bit pliable as I could push on the thicker parts. Once I turned the pump back on, the epoxy had not bonded to the PVC, and so the leak was not stopped. What is even worse was once the epoxy was damp again, it began to soften up even more and had no adhesion to the PVC anymore. Literally, I peeled it off like it was a casted mold. I can't imagine trying to get this product to set while under water. Maybe this is not specific to this brand and this product would work better on a different material, but on PVC piping, it was a complete waste of money.

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.

Works as advertised. Easy to use and waterproof.

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
