I plan to glue some pieces of Teak together to make a block that I will then carve to shape and varnish to make a decorative object. I have heard that Teak doesn’t take glue well. I don’t want the object to come apart due to humidity changes etc. and I don’t want the glue to discolor the wood. What would be the best glue to use, and what surface preparation should I use?

Hi,
I always used a PVA glue like Titebond for oily woods like rosewood. I wash down my glue surfaces with alcohol before gluing. This cleaned off the surface of some of the oils that would prevent a good bond.
Everything that I've read about bonding oily woods speaks to the importance of having freshly cut surfaces. Letting the wood sit around for hours will let the oils rise up onto the new cut surface. The oils will prevent good adhesion.
I have no experience with gluing up teak however. So I would experiment with freshly cut surfaces, cleaned with alcohol or another quick flashing solvent, and then Titebond III. I would also try a polyurethane glue like Gorilla Glue. I'm not fond of the foaming of these kinds of PUR glues so be aware of the clean-up issue you'll face. There are also specially designed epoxies for gluing oily woods. But try these glues first before committing to using them in your project. Good luck. Gary
My experience is that oily woods glue best with a freshly planed and lightly sanded surface. Wiping with a solvent did not help and in many cases seemed to weaken the joint. If I recall correctly, there was a FWW article a couple of years ago that validates this.
Regards
