i was told i need to stain both sides of a pine tongue and groove ceiling . is this really necessary?

Question

i was just going to stain the outside of a 1x pine tongue and groove ceiling im installing. I was told i need to stain both sides to prevent warpage . do i really need to do that.?....much easier just to do the out side thanks.

Answer 1

Stain does not seal wood. It merely colors it. If you are going to seal the wood later, I would do both sides now, before installing. You would not need to stain both sides but seal both or none at all.

Answer 2

yes, to prevent moisture from getting in the boards and making them expand, swell up, or warp. or all of those. I have schalacked them(cant spell that). i wouldnt use stain, u want to keep that nice pine look, use polyurathane(cant spell that either) i have done it so many times, and it stays in nice condition, and looks very nice.
