Review: 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 desertcart 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 desertcart 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.
Review: Neat stuff - First off i do like the product, it seems to work and hold strong. I used it to cement/glue some rocks and wood together in my aquairum. After finishing it seems well put together to where i trust it with fish in the tank. But It was hard to get it to stay on the rock as it didnt want to get off my gloves that i used to apply it. That was the most difficult thing about the process and it easily stains objects like rocks, wood and potentially glass if you accidentally get it on them. I add to use some glue to add moss on the spots i used it and accidentally touched to hide it as it itself and its residue are noticeable.

## Questions & Answers

**Q: bathtub**
A: You need two of them, an outside meadow, a sunset, and some ED medication.   Not sure how you'd use this putty so I won't ask.

**Q: does it work to fix pool leaks?**
A: I bought this as a last ditch effort to fix my pool. The one i already had to replace 2 pump motors and a whole pump assembly on. It was a $200 pop up intex pool from Wal-Mart. I had to patch it once this season but did so with it empty and used a pool patch kit and a crap ton of gorilla tape as insurance. So imagine my horror when i went to shock the "dark green pool" (as the kids described) that the kids won't leave the pump plugged into and see it low. 

Find it leaking and get out that handy gorilla tape. Wasted a whole freaking roll. Still leaking. Its 195 billion degrees in the Midwest and the kids won't leave my doors shut so the pool was how to cool down.

I grabbed this stuff and played with the putty on the way home (per instructions you gotta work with it first) went and shoved a bit into the hole. Fail. Added more.... Somewhat stopped. Still leaking. So i shoved about the size of a quarter into that small hole... Tons on top....

30 minutes later.... Success. For now at least.

Now to see if it withstands more water pressure and a bottle of chlorine for the green pool. Wonder if this will work to keep the power plugs together and running so the kids can't torn off the pump again.

This works beyond great.... Just don't skimp on the amount. The pool is hitting the trash this year.... So i won't know if this works long term... Im just looking for another 7 weeks.

**Q: Will it stick to something already wet?**
A: Yes. I used it to seal a gap between the plastic of my pool skimmer and the grout and tile of my pool lining--all underwater. It worked great and is still working many months later.

**Q: I have leaking pvc that is wet. Will this work on the wet pipe joint?**
A: Yes, it should. Make sure you cut section off with the outer & inner layer of JB Weld & thoroughly blend it together with finger tips.
Rough up entire surface you plan on applying epoxy to with sand cloth/paper so it can adhere to material which it is being applied to. If it spraying water under pressure, you need to turn water off otherwise it will travel under neath putty and escape. Turn water off, clean and sand area, apply putty wait a good hour feel putty should be nice and hard, if so turn water back on. This stuff is amazing, I have used it on 8"-10" PVC leaks at fittings but not under ant type of pressure, it was for a greenhouse cooling system,  I have used it on my bath tub to seal a 1" hole my son punctured with toy in tub. I have used it on natural gas, galvanized pipe to plug hole in pipe. Prep the area clean and sand most important,  doesn't take much putty. My bath tub I did two applications, did first let cure then sand the cured putty and just onto fiberglass of tub again to Rough up give putty something to bond to. I wait a good hour before I test. It's holding like a full on CHAMP from a good 5 years ago. It's good strong stuff, I recommend strongly to my fellow plumbers!

*by D***E on December 17, 2025*

Normally this stuff works well and sticks to most anything. Did not work on my Fiberglass water tank the developed a leak. Sanded the spot. Cleaned with MEK.. applied JBWeld and 24 hours later filled the tank and the leak re appeared.
