Gorilla Original Polyurethane Glue

Great product

This glue is amazing. I don't know about their other adhesives, but this is great. The first time I used it about 6 years ago was to glue and screw 2x12 boards. I use a mist sprayer with water and mist one board and spread the glue on the other and screw together. It foams and hardens and there is no way to get it apart - very strong. I did a dryer repair and needed to glue a felt seal to the drum. Used this and the felt seal was on to stay. I did a test with a heat gun to see what heat the glue could take and it was a lot more than the dryer would put out.

It could be used as lacquer coating. Mix with 50 percent acetone and brush any iitem. It will shine like hell and adhere to any surface. It is isocyanate product which will harden with moisture of the air. the coating will dry in one hour.

This is the original, tough-as-nails adhesive that lives up to its legendary reputation. I needed a waterproof bond for a tricky outdoor repair job, and the Gorilla Original Glue delivered perfectly. The polyurethane formula provides a rock-solid, incredibly durable connection that I trust to hold up against moisture and the elements. It adheres beautifully to almost any material—wood, stone, metal—making it the ultimate utility glue to keep on hand. The only real "watch out" (and why paying attention is key!) is that this glue expands significantly as it cures. You absolutely must follow the instructions regarding surface dampening and clamping, and always use less than you think you need. If you use too much, the expansion will foam out and make a mess. However, if you follow the directions, you end up with an incredibly strong, reliable bond. It's a fantastic, high-performance glue.

I use this glue for most tasks where a polyurethane adhesive makes sense. I have used it on wood chairs, wood tables, PVC structures, wood-to-wood joints, and even concrete bonded to wood. When used correctly, it forms a very strong bond that has held up well over time. One thing I like is how reliable it is if you follow the basic rules. Slightly dampening the surface, clamping properly, and allowing full cure time makes a big difference. It expands as it cures, which helps fill gaps but also means you need to control squeeze-out and not over-apply it. I do not think there is any offensive odor when using this. This creates an opaque fastener and wouldn't use it in any way where it's visibility would be an issue. I keep an unopened bottle on hand at all times. Once I open one, I order a replacement right away. I do not like leaving partially used bottles sitting around for too long since moisture exposure eventually ruins them. Stored sealed, it has been dependable. I consider this a good value overall, though it is somewhat pricey. It can also be more glue than needed for some jobs, and it is not the best option for every application. That said, for heavy-duty bonding across many materials, it has earned a permanent place in my home.

I love all of the Gilded Brand products. This glue was perfect for the project we were working on.

I’m a semi-professional woodworker, and this polyurethane Gorilla Glue has become my go-to for joinery work. It’s a bit slippery at first, which actually makes assembly during glue-ups easier — unlike typical yellow glues that tack too fast and fight you during alignment. Once cured, the bond is rock solid. It can get a little messy if you overapply, so it takes a bit of practice to dial in the right amount, but it’s absolutely worth it for the strength and working time you get.

Works but dries too soon after opening even when sealed properly
