Contemplating porch ceiling material. It’s 16′ above stamped concrete
porch, and protected by a deep fascia. Always envisioned a painted T&G
ceiling there. Just saw a 3/8″ thick, 3″ wide, 8′ long pine T&G board from
Georgia-Pacific, but it’s listed for interior use. If I prime, back-prime,
and paint each board before blind nailing, do you think it could also work
here? If no, what would likely happen? If yes, any other installation
precautions to take to prevent warping or other horrors?
Considered the 4 x 8 pre-grooved sheets, but the ceiling is more than 8′
deep and I’d have that joint to deal with. Other alternative is 3/4″ thick
5″ wide T&G, but that’s more than twice as expensive ($1.25ish/sq ft v
.55/sq ft) and a rougher quality board. Other ideas? TIA.

Jim:
This probably isn't what you have in mind, but consider beaded vinyl soffit. It comes in 12'6" lengths, and, with skilled perimeter treatment (no j-channel), and the right product, other than to the trained eye, it's difficult to tell it's not wood. That's if the porch ceiling width is equal to or less than the 12'6" size of the material. Read < Obsolete Link > this thread, and follow the link I provided. I've done several porch ceilings like this, and it looks great.
*Jim,I'd use the pine with the preparations you mentioned. As long as the roof is good, this should last a long time.MD
*I'd go with the pine. I'd use a good oil based primer too. Just my $.02
*Jim:We use this exact material for covered porch ceilings all the time with no problems. We haven't back primed it, although it would be a decant idea to do so. The only thing we have to watch out for is the roughers nailing it thru the face, and not the tounge.Eric

Good idea. Alas, the porch is about 14' deep.
*Thanks all. I'm psyched now!

All the (real)lumber yards around here carry beaded ceiling board. Usually comes in random lengths. Same stuff that's been going up for at least a hundred years. It's fir, and I rarely even have to do a quick sanding before finishing.Ask for the old fashion front porch stuff at an old fashion lumber yard. Jeff

Tried that. My real lumber yard is who had the stuff @ 1.25/sq ft (or
more). Not a bad price, but if I could do better at no perceived loss
of quality, what the heck... And at 16' height, my eyes can barely see
the grooves, let alone the material type or thickness! :)
FWIW, I also posed the question to Georgia-Pacific. Got a quick
response that said the manufacturer wouldn't warrant any claims if
used exterior and to check out the 4x8 sheets of simulated bead-board.
Not surprised to get a "by the book" answer. At least they responded,
even if it was a bit lawyerly.

Figures.

Check out the wide beaded vented vinyl soffit from Alside.

We use "bead board" plywood on porch ceilings all the time here....with no problems.....it is 4x8x3/8 and looks like the old time 3/4" bead board. I see no difference between installing it vs. 3/8" a/c pine or fir plywood on the ceiling whics is what 99% of louisiana houses have in ceiling which were constructed prior to the vinyl siding epedimic of the past 10yrs...At 8 to 9' the 4' horizontal seam is somewhat visible....on regular plywood we always block planed this joint....when you get to 16' you wont be able to see it....keep in mind all the plywood cornice work that has been done with joints every 8'....at a height of 8' or less......no one notices ......especially with a flat exterior paint rather than a gloss.....you sound as if you are looking at cost as much or more than results so i would go this way.....if you truly want a beaded ceiling with no joints find a millwork shop and have them mill the true 3/4" bead board in the length you need to have no joints....I have done this on ceilings such as in a church and specified no knots.....Got exactly what i wanted and the price was paid....
