A full cure is reached in 15-24 hours. J-B Weld has a tensile strength of 3960 PSI and sets to a hard bond overnight. It can withstand temperatures up to 550ºF when fully cured.

Ideal for professional and heavy-duty repairs. The two-pack offers great value for money. Undoubtedly a reliable product that I would buy again.
Review: Wouldn't be without JB Weld - JB Weld Steel reinforced epoxy has been in my little workshop for 35 years. I've used it to fill voids of various sizes and shapes, repair axe handles, secure knife handles in place, and many other jobs. It will slowly flow to a level surface if you make sure the work piece is properly positioned. I generally overfill slightly, if possible because JB Weld is sand-able and paint-able. I have, on several occasions, drilled and tapped it with excellent results. It's good stuff!

### ⭐⭐⭐⭐⭐ One of the greatest adhesives in the world
*by P***S on June 5, 2025*

JB Weld is the best epoxy I have ever used. I use it all the time for repairs, some that are downright strange. Example: I don't function very well in the AM before coffee, so I accidentally bumped the glass coffee pot for my coffee maker. Make a small crack on the outside of the glass, just above the bottom. So I thought, lets test this: so I applied a small square of JB Weld over the small crack (on the outside of the decanter) about the size of a postage stamp. Let it cure overnight. That was a week ago, and it's doing just fine. I can't believe it...it adhered to the glass and is holding like a crazy man. Saved myself $30+ on a new decanter. I repaired one of my wife's favorite earrings when the small ring that held the dangle broke on one side. Tiny amount of JB on it, let it sit overnight, and gave to her next day. She re-fell in love with me. :) One of the properties it has that I really like is how smooth and easy it is to mix and apply. Many epoxies have thick consistency and are difficult to mix and apply smoothly. JB goes on like warm butter, but dries hard as metal. I'm always using it for something and it's never failed me yet.
