A piece of 24mm ply is about to do duty as a bench-top on which five baseboards are to be built. I've been told that a coat or two of polyurethane varnish will stop PVA glue from gluing the baseboards to the bench. Do the collected sages of WT agree? If so, do I need to use a non-water-based one? Or will a more user-friendly water-based one do the job just as well?
