Clear Gorilla Glue - Good for exotic oily woods No-picture-s No-picture-s Click the pictures to enlarge them

I used several exotic woods for the 2018 mallet swap. Titebond glue was not recommended for use with the more oily exotics such as katalox, cocobolo, granadillo, bloodwood, African black wood. and ziricote. Research came up with Gorilla Clear Glue as a good candidate for these kinds of wood. The local orange box store had it in stock ~$6 for 3.75 oz.

My application was laminating boards together, face-to-face. It spread quite well using a disposable brush. Initially, I applied it too thick and much of the material squeezed out. I also forgot to dampen one of the surfaces on the first use so I’m not sure how that impacts the final cure. It was fairly easy to wipe off using a dry cloth right after application but because it is somewhat oily, it smeared as well. The first piece had smears all over it and all over my hands as well. Using gloves helped. Clamping the pieces was also a bit more involved as the glue didn’t get tacky like typical wood glues so the pieces wanted to slide around. I let the initial pieces sit overnight before taking off the clamps. The dry glue was clear and shiny. Larger blobs came off with a scraper but I still had to sand the wood to fully remove the smears and excess. Even after 24 hours it was rather rubbery. That might have been due to the lack of water on the pieces. I left a blob on the work bench to see how it cured. It is hard but not brittle.

I did have some glue line issues but I’m not sure if it was because I didn’t use the glue correctly, or because some of the surfaces weren’t as flat as they should have been. I tend towards the latter.

Later glue-ups went better and it appeared to do a good job of gluing the dense, oily woods together. I don’t recommend using it as gap filler when gluing since the dry material is very shiny. Overall I give it 4 stars since it appears to have done a decent job with wood that can be difficult to glue.

Here is the technical information I received from the folks at Gorilla Glue (thanks for send it to me!!):
