Can it be used to mend broken denture?

Asked by: Chuck
I doubt it. It sounds like you would have a small surface area to apply it to, and need a bond that can withstand regular pressure. Read my 10/4/16 review where I tried to use it to reattach a metal "twig" flagpole to a metal garden stake - which also involved a small surface area and only had to bond well enough to survive gravity. JB Kwik Weld didn't work well at all for that job. Gorilla Epoxy worked great, though. Good luck!

KwikWeld is rated 3.4 out of 5 by 13.
Rated 5 out of 5 by from when mixed together it is the best cold weld ever. I had a cut off 3/4"x 6" water pipe no threads comming from a wall. Pipe could not be threaded. I was told by a old plummer guy who said get a 1"x3/4" cpvc reducer then reduce the 3/4" to 1/2" for water line and get some sand paper. Now he said get some JB Quik and 1 rubber glove. He said clean and sand the pipe the best I can then mix the JB Quik working fast with glove on coat both pipe and reducer with JB Quik then with a turning motion slip reducer on pipe hold in place using gloved hand to smove around edge of reducer. Give it five minutes and you can run cpvc from that point on. Ohhh by the way that was almost 3 years ago.

Rated 2 out of 5 by from Not nearly strong enough for what I needed, but probably OK for tasks that just need regular glue My wife got a decorative garden metal flagpole stake. No sooner than an hour after she got it, the flimsy flagpole broke off. We're talking about a steel "twig" about a 1/4-inch in diameter that attaches perpendicular to a 5/8-inch diameter steel stake. Mr. Fix-It (i.e., me) was asked to come to the rescue, but I'm more a woodworker than metal expert and have rarely used epoxy-type adhesives. On a friend's advice, I tried JB Kwik Weld. Mixing it evenly was clumsy. The steel is jet black, the hardener is a beige, and they're supposed to mix to a dark gray color. The steel gushed out of its tube on its own as soon as I took the cap off (like it was alive!), but the hardener came out of its tube slow like a slug even with a good squeeze. So besides the steel being "self-wasting," getting a 1:1 mix ratio was tricky. So was knowing when you've mixed enough; the instruction just say to "mix thoroughly." But I got the dark gray color almost as soon as I first swirled the hardener and steel together. If you mix too much, it will start to "goo up" on you and is tougher to apply. As far as actually applying it, it was tricky doing so without either dripping or smearing it where I didn't want to. After putting on a pretty good layer, I clamped the "twig" to the stake and assumed my project was over. But when I came back the next day, it had cured "gooey" with a poor bond. The twig sagged as soon as I stood the stake up, and then just fell off after a few seconds. I ground off the goo with my Dremel in order to try again, thinking I just needed to mix it better. This time I also drilled a shallow hole in the stake first so that the "twig" would have extra support besides just the Kwik Weld. Nope - still gooey, still weak, and didn't hold under even light pressure. After grinding off the goo from try #2, I thought maybe 3rd try was the charm. No again. Clearly, Kwik Weld wasn't going to work. Just to be clear - before each bonding attempt, I pre-cleaned with an industrial-strength Zep degreaser, sanded/filed/gouged the surface area of both workpieces for several minutes, and "mixed thoroughly" as the directions said. Still had poor results. Also, the bottom of the hardener tube unraveled during my 3 tries (probably from having to over-squeeze to get enough out). Hardener started leaking out and I could "re-seal" the bottom, so I'm sure there's no shelf life left on that tube now. The fact the tubes themselves aren't even sturdy is ironic, and reflects how un-sturdy the bonds they (didn't) form were for me. As unsatisfied as I was with JB Kwik Weld, I could see it working OK for projects where the workpieces have a larger surface area being bonded together and gravity is not going to be a factor. But IMHO, epoxy-type adhesives are meant to work in precisely those types of situations; otherwise, its just regular glue! That's kinda all JB Kwik-Weld felt like to me - regular old glue, but with a lot more fuss to using it. One final note - ended up buying Gorilla Epoxy for my project, and it worked great on the first try. That's what I'll be buying from now on.

Rated 4 out of 5 by from Works as advertised Worked like a charm for my project. Similar to the first review of locking PVC to Threaded Pipe. When it says 6 Minutes, they mean it. Be prepared with all of your components before you start. You will not have time to get them together after this product is mixed. In response to odiesdad... It says "Cure Color Dark Grey" right on the front of the packaging. What is there to be fooled about? Giving the product a low rating because you failed to read the packaging is just silly.

Rated 5 out of 5 by from Incredible We have used JB Kwik Weld for so many applications in asture environments it is impossible to catalog all the uses. We have fixed outboard motors (saltwater environment), caving ladders, broken machine gun mounts, broken steering linkages and so many other items. Usually, we use it as a temporary fix until we can get back to base to get the right parts to actually replace the broken part, but there are some items that the JB Kwik Weld worked SO well that we simply left well enough alone. Seems like a MUST for a homeowner, rancher, construction, farmer, military, firefighter, etc. when parts might need to be repaired NOW. I simply cannot understand the review below that says it was unsatisfactory becuase it did not dry clear. No where on the package does it claim to dry clear.

Rated 5 out of 5 by from JB Kwik is the BEST!! I have used JB Weld - the slow kind for many years. It's super strong and always sticks. When they came out with JB Kwik, they went even one better. It seems to be just as strong, but is so fast to cure. If I had any complaint, it would be that a couple minutes longer working time would be handy. I once snapped off one of the die-cast aluminum guides on my table saw. Out of desperation, and not really expecting to be successful, I used JB Kwik to reattach the pieces, then glued on a couple small screws with the heads cut off as reinforcement over the break. That broken part was repaired about 10 years ago and is still in service. I crashed my AR Drone and snapped one of the carbon fiber rods that forms the main structure. I reattached the broken parts with JB Kwik, then reinforced with some small fiberglass rods and more JB Kwik. I have flown over 50 flights since that repair and also had some minor crashes. I think the repair is stronger than the original. I am not aware of a stronger epoxy than this. I'd give it a 10 if I could.
