JB WaterWeld Cure Test - How Long Does it Take to Dry

Here I do a cure test of JB Waterweld. It should start drying in a few hours and be totally dry in 12-24 hours. If it's not drying it could be that it wasn't mixed up enough or there could be something wrong with it.

Some years back, I got a small hole in my radiator (metal part). Found this stuff and patched that hole. Drove like that for another 5 years before deciding to upgrade the radiator. Also fixed a crack in my oil pan. Good stuff.

Very useful and helpful. Very timely for a project I'm starting. Thanks for posting.

[@MyProjectWeekend]

Awesome glad it was helpful! Can I ask what your project is?

[@danalaniz7314]

I'm just using it to build up a waterproof seal between two rocks as part of a large tabletop fountain. I've also used JB products in my wood craft projects.

Thanks for the instruction. Patience means everything. So many were complaining that it didn't cure and this video addresses that issue.

Thankfully I watched this video before using it. Thank you so much for your sharing!

Found this video right after I just used it. I wanted to note that when I was mixing mine up really well, I noticed the putty getting really warm. I wonder if its a chemical reaction or just heat from the friction of mashing it together very wel.

[@callaway86]

Indeed it is, that's an exothermic reaction of the bonding agents.

Thank you. I knew about the need to mix, but this really shows that I need to be sure to mix thoroughly.
Good job on your vid.

Thank you! I hope it was helpful. I used it to patch a hole I accidentally drilled in a plastic drain pipe. You can see that video here if you’re interested: How to Fix Hole in PVC Drain Pipe with JB Water Weld

Don’t you supposed to add a little water to it when you pressed mix with your fingers??

This stuff is garbage. Wouldn’t seal a leak on a hose reel 60psi and yes it was rock hard
