I am installing 1X8 T&G pine for the ceiling of a porch. Is it necessary to prime the backs of the siding before installation? The visible surface will be painted, not stained.
Thanks, Bill

The best tool for straight, splinter-free cuts is made even better without a cord.

In addition to backpriming, you'll want to make sure that the tongues have all been painted in the final color, before the ceiling is hung. Otherwise, normal expansion and contraction will expose unpainted lines.
Unless you're the lead dog, the view just never changes.
Heard enough now, from all us perfectionists? I would get some alkyd (read: oil based) primer, get your paint store to tint it to the color you'll use on the face, thin it just a little, and then prime all sides, edges, and ends, of every board. This, before you put up the ceiling.
Then put it up, but keep a small can of the primer nearby when doing the work, and hit every cut end with some primer as you cut. Pop it all up and admire your work.
Then finish in place with a good exterior latex.
The combination of alkyd primer and high quality latex is the best for exterior painted wood. Unless you tire of the color, you'll never have to paint it again.
Thanks for the advice. Now all I have to do is hope the weather stays warm enough here in MN to get it done!
It's a good idea because it makes the rate at which moisture enters or leaves the wood the same on both sides. That tends to keep the wood flat rather than curled.
