Join between panels on desk not smooth due to warping
Apologies in advance, I am not an expert. I have an old french desk which has a top comprised of 8 panels. Although the rest of the desk seems solid wood, the top seem to be a thin wooden layer. It has been exposed to sun and some moisture, which has caused one of the panels to raise a little making the join uneven. There is “play” in the raise section so I can push it down. Does anybody have any ideas on how I can stick it back down?
