July 31, 20196 yr It might depend on what chemicals were used. You'd probably be ok with the newer stuff, though.
July 31, 20196 yr Check moisture content. In short if just bought and heavy, it's not ready for gluing just yet. Neighbor learned this lesson recently. Now this was extreme but the board when squeezed slightly dripped water.
July 31, 20196 yr This is one of the few instances where polyurethane glue (e.g., Gorilla Glue) might be appropriate -- it needs water to cure. I saw a video recently of a guy building a flat-bottom boat from plywood. He put a sinuous line of Gorilla Glue on the joints as he assembled, then spend the next half hour scraping off the foam from time to time. I guess best attribute is that it's waterproof. Cons: - stains flesh - ruins clothes - goes bad in container (short shelf life) - foams out of joint, making a mess to clean up with chisel or sandpaper - must be clamped or it can blow joints apart - no known solvent - if it doesn't hold, you have a mess to clean up before you can use a different glue - fills gaps, yes, but with foam that has no structural strength - in a FWW article a few years ago, it was the only glue that failed in a not-so-tight fitting joint Edited July 31, 20196 yr by kmealy
