Hello,
What is the feeling here about painting/varnishing the underside of pine internal doors? I've hung my doors and will soon begin the laborious task of varnishing them, but I am loathed to remove them just to varnish the underside.
Has anybody not sealed the underside and later regretted it? e.g. the door has warped as a direct result of the underside not being done.
Thanks,
Graham
???? I'm sure if you are really troubled by it you can find some ingenious way of getting some paint ( or some other sealant) on the underside if there is any sort of space at all....but I wouldn't really bother .
If the door is going to move, it'll move. Sealants may slow the process a little
If it going to be wet and an exterior door ok, but its a waste of time on interior doors
no point at all in doing that. Varnish doesnt provide enough of a 'seal' to prevent warping.

I agree with your sentiment for all the wrong reasons.
Bare wood kept in a dry house won't warp (at least, not once it has initially dried out) so it isn't worth doing.
But varnishes have been used on boats for years, and they do keep the water out!

They keep water out, but not water vapour. That's what causes wood to expand/contract.
