Fix for a hard-to-replace sink part: strong grip + easy to shape
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. ⭐️⭐️⭐️⭐️⭐️

General user that hates to throw away things that break or needs fixed.
Used this product to fix leaks holes on canoes and pontoon floats as well as a cracked plastic utility tub. Worked great in all uses!! I combined with the syringe product in some cases, but the putty sticks are very easy to use since you can get it exactly on the right spot easily! Recommend this and other J-B Weld products highly!

The possibilities are endless
This stuff works really well. It's sort of a "Mighty-putty" type product if you ever saw those comercials. Make sure you wear gloves when you mix it because it's super hard to get off your hands and it smells pretty bad. I used it to patch a small hole in the tile in my bathroom where the guy who installed the tub faucet cut the tile too large and there was a gap. This worked perfectly. Where it didn't work was outside on this wooden beam that had a chunk out of it that I wanted to fill in. I thought I could stuff some of this in the hole, wait for it to harden, and then paint it, but I guess it doesnt stick to wood very well. It kept just falling right off. There's endless uses for this though. I keep it in stock at my house for when something comes up. There was a little gap in my baseboard and some ants were getting in and I used this to patch it. You get the idea.

Note the 2oz size - you may need a second tube.
Great product as always from JB. I did noy pay close attention and failed to note smaller than usual size for this product. I would have ordered two. The stick inside is about an inch shorter than many similar stick type epoxies. Didn't run short, but it was close. Works as well as any other product sold for the same purpose. Working and set times are as stated in instructions which you must follow, especially on fiberglass repairs. Roughen and clean both surfaces and you will get excellent adhesion for permanent bond.

I refurbish and repurpose cast iron cookware and pretty much anything that's cast iron because it's my passion
I refurbish and repurpose cast iron cookware and pretty much anything that's cast iron because it's my passion. When my boss who owns a barn in Connecticut that was built in the 1700's found this out, he immediately thought it would be a fun challenge to start digging up old cast iron pots that he would find in the ground in his barn to bring to me to see what I could do to bring them back to life. The first project he gave me was an antique S&P Kettle pot. It was severely cracked on the bottom. When it comes to cast iron, you have to weigh your options and in this case it really wasn't worth having somebody weld it together for me because it could have created more damage because the crack was that severe. I felt because this wasn't going to be used for cooking and a great repurposing project, I consulted with my service managers because they work with these kind of materials and would know what kind of bonding agents in materials would be best to use that would be effective to do the job for these kind of projects. Because my job involves working with plumbing and cast iron and things of that nature, I knew that I was talking to probably some of the best resources. They recommended this product and I purchased two tubes from Amazon because I wasn't sure exactly how much of this stuff I was going to or needed to use. Sometimes it's always hard to tell from the picture on Amazon as opposed to what you get when you actually receive it in the mail. It is a putty type material and it is white. I only used one tube and not even close to half of it so a little goes a very long way! The putty works perfectly and it goes within the crevices that you needed to and you can shape it but you have to make sure you do it quickly before it dries because it does dry quickly as well which is great. I didn't want it to be perfect I shaved it enough to fill in the huge crack. Because it's white I knew I didn't have to make it look pretty because I knew I was going to be repainting the whole pot once the putty had dried. Before I did any painting, I did a test just to humor myself and I filled the pot with water. I have to say that no water left that pot anywhere and if I wanted to use the pot for just a planter at this point, I am incredibly confident that I could do that without any worries of leakage. So I have plenty of this left for the next time I come across a crackpot repurposing project and I'm excited with the fact that I have a product that is amazing and will definitely be able to use and it will work. So whether you're going to use this for plumbing needs, repurposing needs or whatever, not only is the price right, but this stuff is awesome. It does the job. Again though just to be clear, it is white and dries white so if Aesthetics are an issue for you, you should count on definitely painting over it with the color that matches the item that you're working on.

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.
