I'm trying to decide whether to use 3/4" birch plywood for the "surface" of my next layout which I'm planning to be a "domino"-style modular layout and I am concerned about how well 3/4" birch plywood will hold up against the humidity variations in the Midwest.
I'm thinking about attaching the plywood to the framework with serrated nails, and paint the plywood a neutral tan or sand color to seal to hopefully at least partially mitigate the warping effect of the humidity changes.
I can keep the train room at 55 - 60 degrees in Winter and under 80 degrees in Summer, but due to cost considerations, I cannot do any humidity control except what's supplied incidentally by the HVAC system.
My bottom line question is: will using 3/4" birch plywood work in this scenario?
I would appreciate any ideas, opinions, questions, comments, etc.
