It’s a 3-season porch and the existing ceiling is drywall. It hasn’t held up too well over the years (not surprisingly). My customer is trusting me to replace it with whatever would be appropriate.
I’m thinking 1/4″ luan plywood glued and screwed and then a gridwork of stop molding (or similar) to hide the seams. The whole thing gets primed and painted.
Is this a good plan? There a probably more attractive options, but it’s hard to beat the price of luan at about $10/sheet.
Also, which side of the luan should face out? One side is light and one is dark. I’ve never used it “outside” so I just chose to expose whichever side looked better. I suspect it doesn’t matter on a porch ceiling either.
