About J-B Weld
How It All Began: A Mom And Pop Operation
The J-B Weld Company was founded in 1969 by Sam and Mary Bonham. Sam had discovered a need for a 'cold weld' product to use in his truck service garage, instead of traditional torch welding. Working with a Texas A&M chemist, he formulated an original 'tougher than steel' two-part epoxy and named it J-B Weld. Sam and Mary soon went from selling the product out of their car to auto parts jobbers across Texas, to selling it in stores throughout the U.S. and internationally.
J-B Weld Syringes won't dry out
The re-sealable, no waste cap found on all J-B Weld Syringe products only screws on one way to eliminate accidental mixing, ensuring the epoxy will not dry out between uses.
Know Your Bond
Not All Adhesive Bonds Are The Same.
Have you ever thought about how an adhesive works? Or why you should choose one type over another? So often, it’s easiest just to grab that bottle of glue from your kitchen drawer and hope it will fix whatever needs repair. But once you know the differences, you’ll say: Why glue it, when you can J-B Weld it.
We’ve created a simple chart to help you compare the different adhesive bonding systems out there. You’ll quickly see how the strength of our J-B Weld two-part epoxy products makes them stand apart from all the rest.

Printed on the package are the 4 instruction steps: Prepare, Mix, Apply, Dry. There is an asterisk following step 4 that states you should wash the parts in detergent and file or sand the surfaces. I missed that asterisk on my first try. The instructions say it cures in one hour above 40F degrees so I let it cure for 5 hours at 75F because I had applied it somewhat thick. After 5 hours it fell right apart under weight. Partially my fault for not sanding/filing but the epoxy still hadn't hardened after 5 hours. The product I received dried completely clear and transparent.
Tip: Score the surfaces with an Xacto knife. This should absolutely be step one. If you are repairing broken plastic, sandpaper will not likely reach all of the uneven, broken surfaces to be joined and a file would deform them, ruining the shape of the seam to be joined.
On my second try I used the Xacto knife to deeply score the surfaces. I really recommend doing this as it gives much more surface area to adhere. I then scrubbed the parts with detergent and splashed them with 91% alcohol. This time I allowed it to cure over 48 hours and so far it's holding.
My advise is score the surfaces well and let it cure as long as you possibly can.
Upon receiving the PlasticWeld, I opened the package, tore a flap of the cardboard Amazon box that it came in off, and grabbed my laptop. Used sandpaper to rough up the plastic where I needed to glue it back together which also cleared out some of the old adhesive the manufacturer originally used. Used the cardboard as a mixing tray, squirted out a good bit of the weld mix onto the cardboard and mixed it all up with the provided wooden stick. Once mixed, I positioned the laptop where the plastic pieces were pulling apart and then used the wooden stick to swab the weld onto both pieces of plastic. After thoroughly coating both pieces I closed the laptop and pushed the 2 pieces of plastic together. After wiping off the excess weld which oozed out, I stuck the laptop under the couch cushion where I was sitting and ate my lunch figuring my weight would hold the pieces securely together while it set up. Bout 30 minutes later I pulled her out and saw no separation of the parts and left the laptop to cure overnight.
After that, I have been using the laptop on a daily basis and have seen no issues from that area again. Strong bond that is resisting the tension of opening, closing, and constantly adjusting the laptop screen. I cannot say that this product will work well for all applications, but it sure did the trick for my limited needs and I can think of times in the past that it would have fixed a product that I ended up throwing away.
