Re: Pine Ceiling - to finish or not to finish?
Pine will darken over time, and you may prefer that.
I have the same boards through the entire house, and they have been there for ten+ years. The finish was intended to slow the darkening process but leave the wood as light as possible.
The finish is very light, (i.e thin) and I did not relish the idea of putting it on the ceiling, so all boards were finished (two coats) before they went up. There has been no maintenance required. I would do the same thing again.
BTW I have the same boards under the soffits and deck roof with an exterior finish and the soffits have required refinishing, teh deck ceiling does not .
