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. ⭐️⭐️⭐️⭐️⭐️

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.

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.

Works great for my sprinkler pipe
It works great on a L shape elbow pvc joint in my sprinkler box (about 80psi). There is a very small leak in my sprinkler box, found last fall and confirmed this spring when turn back on the water (photo 2), there a few hair size water shoots out from it. I removed the component and brings to Home Depot, but they said the manufacture is no longer making it (or out of business), and they do not have any replacement in similar size. So for me, try some alternative solution is the only way to do before spend hundreds to hire professional. I decide to give this a try to this patty before really hire someone to do it, and thanks to many other reviews in this post, even a lot of people says it doesn't work with pressured pipe, I did see there are people successfully make it works. Based on all other people's experience, I did the following steps with extra caution: 1. clean up all the dirt and debris, wipe out clean with paper towel. 2. rough the surface a little bit with a wood sandpaper (barely add some scratch on the surface, to improve the bond between this patty and the pipe). 3. discards the first1 inch of patty on the edge (some people recommend so), then take a about 1 inch of patty for first application. knead it to bar/snake shape and fold it, repeat for dozens of times. 4. after it fully mixed and soft like peanut butter, make it like bar/snake, wrap it around the leaked position (like a ring over your finger), push it to the surface and smooth the edge (like a band aid around the ring over your finger). 5. wait 1 hour to 2 hour for first application to harden a bit (the first application only becomes slightly harden after an hour), then do the 2nd application same way to "patch" the 1st application (use 1st application to seal the leak, 2nd application to seal any potential leak of 1st application). 6. wait 3 days instead of just 1 day to let it fully cured (assume there are moisture in the pipe and it take longer to dry) So far it works well after turning water back on and no more leanings. I will keep monitoring my pipe, in case if it leaked again, I will update here. note1: the product i received says its strength is 4370 psi (picture 1), which is much higher than the label in old picture and another product in home depot. I guess that extra strength may also helps if the product is fully cured. note 2: if your hole is larger, you may need more putty to add extra strength than how much i uses. but i still recommend multiple applications than use everything in one shot. ---- update: June 12 patched another garden hose with 2 steps. it works for a week but leaks soon after a few usage, i guess flexible pipe may need more skill & patient.

Adheres well and sets up strong.
Mix it well and it will treat you well. I put on some gloves. I break off the amount I need and roll it around between my palms while pressing firmly. I can feel the heat of the reaction starting as it warms in my hands. Then I squish it into place and mold it into the shape I need. It sets up very well in 1 hour.

Did not bond to PVC pipe
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.

Fixed my outdoor faucet - 2yr update - failed from age
2yr update: So I just did a bit of power-washing and came inside to a flood! I even used that faucet not long ago and had no leaking then. So seems like it just gave up over time as it wasn't re-cracked from new freezing. I'll be getting a new faucet/pipe this time. So, revised to say that this is a fine temporary fix but wont be good to rely on it long term. Original: I had the outdoor faucet burst from being frozen. Found out when turning on the faucet flooded the converted garage. The pipe is already exposed in the garage so I didn't want to go through the trouble of turning the water off and changing the faucet. I put this on the crack in the pipe and took the rest to wrap it around just to be extra sure it would hold. I waited till the next day to try the faucet and it's all fixed now. No more flood or leaks and back to full pressure outside. Great stuff.

A Must-Have for Emergencies
The day before a week-long trip, my wife tells me the kitchen sink is clogged. Not what I want to hear at 10pm the night before I have to wake up at 4:30am for an early flight. So after using the plunger and then the snake, I finally clear the grease clog enough that I can go to sleep at 1:30am. I get home a week later and I try out the kitchen sink by washing some dishes as a test. Great! The water went down. Then I step out to the garage (where the waste line runs through) and find rivers of water trickling all over the floor. After moving the washer and dryer out of the way and knocking out a foot of concrete around the waste line, I find water pouring out of the galvanized pipe through a corrosion hole. Apparently, the hole was being covered by the built up greasy sludge and the snake moved the sludge out of the way, allowing all the water to run down the concrete block wall. As I was contemplated popping a new hole though the wall and into the kitchen cabinet so I could run a temp PVC line (I am redoing the kitchen soon anyway), I realized I had bought this J-B WaterWeld Epoxy some time ago "just in case". So I thought "what the heck" and tried it out. Worst case, I would have to run that new line anyway. Well, s---fire if it didn't stick to that galvanized pipe and seal that hole! Even though it was still dripping water, that patch stuck and cured in place just like the packaging says. I had to use a second patch because it was still leaking from somewhere I couldn't see and that second patch sealed the deal. Now, I am treating the line with some Green Gobbler Enzyme to keep the sludge at bay until I replace everything in the kitchen reno. A couple of tips: 1. Clean the area first with a degreaser, as the packaging says. This was essential to me because all sorts of cooking oils had been coming out of that hole and you need that stuff to stick. 2. Use a knife to cut only what you need and mix it in your hand using a glove. That stuff is very sticky and won't easily come off your fingers. 3. If patching a hole, form a patty after you mix it and apply and them smooth the sides of the patch. It will mostly retain it's form and get rock hard in a few minutes. 4. Finally, don't wait too long to apply. You have a few minutes to apply it, otherwise the chemical reaction will start to harden it and it won't stick. I am so glad that I had this stuff on hand. It saved me a full day of breaking concrete block and fitting a new temp waste line. You can see the patch at the bottom of the pipe. Because of the location, it had to be done by feel and I did take off the glove. But it wasn't so bad after it had been mixed. Update 8/23/22: After 6 months the patch is still holding strong with no leaks. That's a relief considering the kitchen reno is taking longer to get started than expected. But that's another story...

Dichtet zuverlässig, auch wenn es nicht hübsch aussieht
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.

Just the job for small repairs to water butts or tanks.
Fixed a small leak in my plastic water butt by applying this putty like adhesive following the supplied instructions. Water butts are surprisingly expensive to buy so finding this repair kit has been a sound purchase.
