I bought lumber for a screened patio, and I need it to dry so I can paint it before construction. It’s been sitting in a neat stack in the garage for almost a month now, and some parts still feel damp.
I’m afraid that laying them out on the driveway during a sunny day would cause the boards to warp.
This could be a bad suggestion but do you have a dehumidifier? I would loosely stack it so air can get through, so crosshatch type stacking. Place some cinder blocks or other heavy weight on top to keep it from warping, and then put a dehumidifier in your garage.
Honestly having a dehumidifier is worth it regardless of this project so you should probably buy one anyway. They can turn a not so fresh smelling room in to a much better smelling one. They can help inhibit mold and fungal growth. They can even help reduce cooling costs depending on how they are connected and vented.
