grizzmans post on warp in table top prompts this question about my table top made of 8/4 cherry i used varathane wood sealer over whole top but only finished top and sides with waterlox will that be enough or should I pull the top and finish the bottom no problems yet been in the house about 3 months
This is another of the stories that are told and retold until they become "so called facts". Next time you have the opportunity examine the underside of as many antiques a and note how many of them were never finished.
I routinely seal the bottoms of any flat surfaces I want to stay flat. I agree, I've seen lots of antiques that were never sealed on the unseen sides, but I have personally seen stuff warp with unfinished sides. Maybe they would have warped anyway. That being said, I never spend as much time on the unseen sides as I do on the seen, finished sides. I think just sealing it is enough and, so far (15 years maximum on an MDF drum sander table, laminate on the finish side, 1 coat poly on the unseen side) that seems to be enough.
