Unpopular opinion: stop gluing up face frames with Titebond III, a failure at a client's house in Boise switched me over
Last month I was installing a set of painted maple face frames on a built-in in Boise and one of the top rails popped a joint about 3 hours after I set it in place. It was 91 degrees in that room because the homeowner had the heat cranked for paint curing, and the glue just let go at the joint line like it was nothing. I had used Titebond III on the whole run because it's what I had in the truck, and I always figured waterproof meant stronger down the line. I peeled the whole rail off, scraped it, and reset it with a polyurethane glue and it hasn't moved since. Talked to an old cabinet guy in Nampa who has been building for 30 years and he just laughed and said he quit using yellow glue on face frames a long time ago for anything that ships out of the shop. The thing that got me was water resistance doesn't mean anything if the glue creeps in the heat, and cabinet interiors in a closed house in summer get up over 100 easy. So now I keep two glues on the bench and pick based on where the piece is going. Has anyone else had a face frame joint let go months after install, or am I the only one who learned this the hard way?
