Gorilla Epoxy Ultimate, Waterproof, 10 Minute Set, Permanent Bond, Dries Black, 0.85oz Syringe (Pack of 1)

I used this for installing a black granite counter (the seams between pieces). It worked beautifully. It was the only black epoxy I could find and the final results are fantastic. The bond is rock hard and strong. It sets quickly - you really only have 10 minutes max before it's not workable. It goes on non-flowing so it would work well on vertical surfaces. Extremely easy to apply - just break the tab, squirt onto scrap material and mix with included applicator stick. The only thing I needed that wasn't in the package was a standard razor blade to press it in the seams and shave it off (which you should do before it completely sets). You would think it would be a nightmare to clear up but it cleans up amazingly well and quickly with acetone. Rubbing alcohol works too. Just apply it with a paper towel and it instantly starts to dissolve (turns bluish!) . I did this after about 10 min. I think it will be much harder or impossible to clean up like this if you wait much longer than 10 min. Because it's a two-part epoxy it stores well for continued application at a later time (no drying the tip shut like regular glue). As far as quantity, I needed about 2.5X as much as I originally thought, but that might just be my inexperience. I was not able to return the one leftover tube because it was "unreturnable". But since it stores well I now have a tube of great black epoxy if I need it!

Amazing! We used this to fix a metal chair where the mesh was coming away from the support. It needed to be welded, so I figured I would give it a try. The hold was fantastic; and the chair is functional again. Worked great! It definitely smells strong; even doing it outside, my husband was overwhelmed by the chemicals (it did not bother me at all). It does set quickly, so keep in mind, you do need to work fast. Great product!

Worked good used for seam in granite counter repair

Gorilla products are durable and adhere well. This hardens up well and there is no stinky smell.

Worked well. Make sure that you are in a well-ventilated area. It is quite powerful.
