J-B Weld 8267UK SteelStik Epoxy Putty, dark grey

I've had a tube of this since 2019. I don't remember what I originally bought it for, but I used it successfully this weekend on a zinc plated coach bolt, to cover the threads and enlarge the overall size of the bolt as a striker for a self locking gate catch. I pulled a 3/4 inch piece from the tube, kneaded it for a couple of minutes until it started getting hot and then pressed it and shaped it until it set hard after five minutes. Initially it doesn't stick well, be patient and press gently in/on to the area to be puttied, it gets stickier as it warms up. After an hour, I was able to use sand paper and metal files on it. It sets as hard as steel, it dries a matt dark grey colour, antirust and can withstand temperatures as high as 300 degrees celcius. I've heard that this is particularly good for patching leaks in plumbing and the packaging says that it is food safe, so presumably it would be suitable for copper pipes for either central heating or mains water. I'm impressed by the versatility and long lasting nature of this product and know of many people who swear by this when everything else has failed them. It's so easy to use and it's definitely worth keeping in the toolbox for repairs of all sorts whether it's plastic or metal.

I used this steelstik on a very damaged car sump some weeks ago and so far it has made the repair. Very pleased with the product

WORKS WELL

Works brilliantly, Easy to use. I had to join a very heavy cast iron downpipe that had broken completely right at the flange section. Faced with a horrendously expensive replacement of the whole thing I looked at other options and found this product. Once I'd cleaned the area to ensure a solid base to bond, I used a smaller diameter plastic pipe asa liner to join the two pieces and take some of the weight. Once I'd placed the pipe exactly into original position, Ifixed the pipe securely to the wall with standard brackets and rolled this stuff into a pliable consistency and placed pieces all around the circumference and pressed it firmly around the fault line into as neat a finish as I could. It set quickly but I left it for an hour or so before using a sander to gently smooth any excess. Once painted, it's hard to see where the join is. This stuff could save the day in many situations and is well worth having in your tool box even as a "just in case".

Brilliant stuff. Does a great job. I built a long safety barrier using metal poles with chains bolted to them. JB did a great job of securing all the threads and fixings. Really happy with this. NOTE; If you get this on your fingers. Let it go hard for 10/15 minutes then use hot water to 'ping' it off. Use hot water or it will not separate from your skin. Great product.

Lifesaver. Or should I say car saver. Why have I not known about this stuff all my motoring life. My classic Impreza boot lip had rotted as they all do. This meant the boot and side jack pocket were filling with water. I was able to rebuild it with this! The boot doesn't appear to be leaking now. Now it does harden within minutes once mixed and can be a bit tricky to stick but once dried it's solid. I've ordered another 2 packs to rebuild my other classic car which needs alot of it's boot lid patched. Wish they did a hotdog sized roll. I brushed and dosed the bad spots with rust converter before using this. Once it was dry I didn't bother sanding, just sprayed with zinc primer and truck bed liner. It does have a strong smell but nothing you need a mask for. Just a brilliant product.

I bought this to fix some poorly welded struts on my kids metal frame bed which had snapped. Application was very easy, just cut as much as needed off (it is covered in plastic, but it cuts very easily), knead it and then apply like putty. Just use as much as you need to for the moment though, because I cut off enough for two jobs and the bit I'd set aside for the 2nd part was already setting and difficult to use in the minute or so I had applied the first... it starts setting immediately! It set very well, completely rock solid. I had honestly expected that it did the job perfectly. Unfortunately it only lasted a day... the next day it had cracked and broken (the first job, I redid the 2nd with fresh because I couldn't use the original bit). It clearly couldn't handle the compression and tension of just normal usage on the bed, which probably explains how/why the original welds broke? Maybe? In either case, I'm not completely happy as it didn't do what it was supposed to, but I can imagine in other scenarios where it's not under changing loads and demands, it might work better.

We used this to fill holes in the floor our our van before converting it to a camper. It’s really easy to use (for a complete novice here). Sticks well, mixed easily, dried quickly and it was solid! No problems whatsoever.

Entrega mucho antes, calidad muy buena, lo usé para colocar soportes para extintores de 2, 6 y 10 kilos y funcionó muy bien. Recomiendo lijar ambas partes, antes de colocar el material, dejé secar un día y listo.

Well written instructions that is easy to follow. Easy to apply. After about 6 weeks, I do not detect any evidence of any more leaks. Looks like it has worked well.

Was skeptical about this stuff but WOW it really works. I managed to get a nasty cut in one of my tire stems from having to saw off a stuck metal cap which caused it to start leaking air and made it impossible to fill the tire. Decided to order this stuff on a whim in an attempt to save on a costly repair or replacement and I couldn't be more pleased with the results. I shoved a little piece into the gash and let it cure for a day and my problem is completely fixed! Tire has stopped leaking air and fills normally now and the patch feels totally solid, amazing product for real.

Solid and reliable

Good epoxy repair option for minor household repairs.
