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

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.

Works great! Smells like a baboons hind quarters but the epoxy mixes and molds very easy in putty consistency. Stopped drip on some supply PVC connections in seconds, hardened in about an hour. Much easier than tearing things apart.

Works great in my pool skimmers. Just mix well..

I love JB Weld products, but this putty did not work on a pressurized pvc pipe with a tiny pin hole drip. I sanded, wire brushed, cleaned and dried, mixed putty wrapped it on pipe smoothed down edges and it started making bubbles under the putty. I knew it was not going to work then, i kept soothing it out trying to clog the pin hole, i let it sit for an hour checked and it is still dipping. Gotta get some pvc parts and get to work. IM sure it works for some applications, not with active dripI gave it an hour and checked back it was not leaking, two days later still not leaking. JB weld is good stuff.

Even though the ratings on this epoxy putty isn’t the best. I think people just don’t know how to use it. The putty has done many thing and never had a problem. I have used this for my pool that had a very thick cut in the skimmer from degrading and this putty bind it to the plastic and causes a permanent seal.I also used this for a small hole in the attic where recent roofers pulled nails out when redoing the roof and left the holes exposed and this putty binded to the wood, making it a permanent seal.

Used this to fix a small leak, and so far it’s holding up great. I cut off a small piece with a tool, mixed it by hand (definitely wear gloves), then pressed it onto the area. I applied it around 10 PM and waited until the next morning before turning the water back on.The putty was easy to work with and hardened nicely overnight. Just make sure to knead it thoroughly until the color is uniform before applying. Overall, very handy to have around for quick emergency fixes.

Designed to work underwater or on things that are 'wet'. It is a putty, so it will stick in any position and not 'run' downhill before it cures.To use, you break off how much you think you need, and start kneading it between your fingers (wear rubber gloves). There is a center core that is a different color than the outside. When it turns a solid color (no streaks) it is completely mixed, and ready to apply. Sticks to CLEAN surfaces, even if they are wet, provided they are not under pressure. It can be put on the inside of a fish tank that is full, because the water will not try to push it away. I used it on a cracked water hydrant pipe. I mixed/applied the putty, and it seeped. I mixed more putty, and it seeped slower. I had the pipe cleaned up good, and was applying the putty maybe 1/4 of the way around the pipe, with the crack in the middle. I thought about it a while, and wondered if it wouldn't seal better if I just mixed up the rest of the package, and made a patch that went all the way around the pipe, extending about 1/2 inch or so past both ends of the crack. Finally, it was sealed, and has been holding fine since early spring.I gave it 3 stars because it didn't seal the first time, but I'm thinking it might have, if I went all the way around the pipe from the start. Since I don't know for sure either way, I give it an 'average' rating. It worked as intended, but not perfectly the first time (at least for me).
