Answer This Question
A:Â It might, but there are other products better suited to the application & easier to work with. Flex seal is 1. Rustoleum makes 1. Whatever you use, you will have to cover both sides if possible.Â

A:Â No, this product is not designed to stop leaks.

A: It may or may not… Probably not the right product for that. Thinking you should be heading for a cement base product.

Worked great and as expected
[This review was collected as part of a promotion.] This stuff works extremely well. I used it for some of my crafts that I'm working on. It worked well to lay tile in a miniature house and it was easy to use. The process is fairly easy as you just mix the two together. It takes about 3 to 3 hours to set and about half a day to cure, so don't use whatever you're working on until it's very cures.

This Stuff Really Works!
[This review was collected as part of a promotion.] I tried the J-B Weld Original Cold-Weld Formula Steel Reinforced Epoxy ant this two-part epoxy system really works! Using an old ceramic glass plate, I mixed an equal amount from each tube and smoothed it onto my metal parts that I wanted to glue together. I left it to dry all through the night, and the next day my metal parts had adhered just perfectly well. I honestly love how easy it is to use, just being careful not to put it on my fingers, but this J-B Weld product really works!

Good
[This review was collected as part of a promotion.] I got the J B welding from Tryit sampling. This will be a great product for my husband’s trailers and wool tools. He can use it for repairs. Having something on hand to use when needed is a great thing.

I used this product to fill deep gouges in a wooden desk I was completely refurbishing. It worked perfectly, filling the gouges easily and can be sanded to perfection. No signs of any gouges ever existing after applying the finish. The desk looks brand new again!

In a parking garage my son hit the ticket machine and it broke off the side mirror. The only thing actually broken was the plastic plate that's between the mirror and the door. I used the JB Weld, with several finishing nails perpendicular to the crack to repair the plastic plate. Did one side and a day later the other side. The JB Weld hardened up very well, yet gave plenty of time to work it. Much cheaper than having a shop do the work or buying a new mirror.

This product is awesome
Follow simple directions carefully and it works perfectly. I thought this table was trash, but fixed it perfectly. And it was right where it was supposed to be in the store.

Excellent product
Used this to repair a cracked concrete bird bath. Bird bath is 2 feet wide with a leaking crack running 2/3rds of the way across the base. Best way to describe the end result is it's essentially an epoxy weld.
It's very easy to use and doesn't expand like other adhesives. It adheres to practically anything and hardens rock solid (although not a brittle solid). It dries a pale grey but is paintable if needed.
Highly recommended for tough adhesion jobs.

This project was to repair a shower door hinge.
Worked great as usual.I have nothing negative to say about JB Weld. I have used it for years and never use any other epoxy.
