Good board choice to cover a wall that holds paint?
In our long hallway we want to cover the walls with a thin board and then paint it. The walls now have several layers of VERY old wallpaper (1940 on) that only attach to large horizontal wall boards with small gaps between them. So we want to just cover it up rather than remove the rest of the paper. What's the best choice that's cheap and hold paint well? Thanks!
Another option is cheap 1/4" thick drywall....you may need to get creative where door molding are involved.
Thank you!
