    Plywood movement from moisture

    Does plywood expand or shrink much due to seasonal changes in moisture, or is it considered negligible?

    RE: Plywood movement from moisture

    Walter! It's good to see you back here again, man! Been quite a while. I've wondered where you were from time to time.

    Plywood's movement with humidity changes are pretty minimal because each layer helps prevent the other layers from moving. Even at that, it's not a bad idea to seal the edges of the plywood if it's going into something critical.

    I had another child, moved into a new home, and changed jobs. Its been a busy two years. I'm finally getting my mind back on some wood working.

    If you want to use plywood for a raised panel, you can edge it with solid wood, and then do the bevel or a profile to the edge. What you wind up with is a very stable panel without movement issues, and no end grain showing. You could use a contrasting wood for the edge and create an interesting look.
