In my previous posts here and here I have referred to product called Chair-Loc. This is is labeled on my bottle as “rosin triethanolamide”. My bottle was made by The Chair-Loc Company of Lakehurst, NJ.
I have not been able to find Chair-Loc in local stores. I found that it might be available at Contantines Wood Center. Either a 2oz bottle alone ($4.25) or a 3oz bottle in a kit with syringe and tips to inject the joint ($11.95). Also at Western Wood Doctor with similar but different pricing.
Google search and Amazon provide a number of false leads and alternatives.
Wonderlokking Tite Chair glue is a cyanoacrylate glue which may work well at repairing chairs. The problem is that is really is a glue. If you have to disassemble the chair to repair the wood, covering, or as a result of refinishing, the glue will stick to the wood fibers and tear them apart. My theory is that if you want to repair furniture, you want to do it with glues that fill, swell, tighten, but do not stick. CA glue is sticky, particularly if you get it on your fingers.
Behlin Swel-Lock (scroll to page 16) may work, I have not tried it. The MSDS says that it is dipropylene glycol. I see information on the web that antifreeze (ethylene glycol and diethylene glycol) is a traditional fix for loose ax handles. I have not used it and cannot comment on how well it works or how long it lasts.
Briwax ChaiRX is a self-crosslinking vinyl acrylic polymer emulsion. While the MSDS states that the emulsion contains a large amount of water, if, on drying, the vinyl acrylic polymer remains in the wood fibers and joint, the joint should remain tight some time. This may be the best replacement available today for my favorite chair repair.
Briwax MTD, a wood sweller for mortice and tenon joints appears to be similar and may work as well.
When I get time, I will update the links to Chair-Loc in other posts to point to this info page.
