J-B Weld WaterWeld

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.

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.

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.

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...

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.
