I have a 4x7 section in my garage that is concrete that the builder did not put drywall on. I want to put plywood on it or something else so it blends with my new paint job on the rest of the garage. Any ides on the best type of wood(plywood,osb?) to put on it and the best way to attach?(tapcons?) Thanks for any help for this brand new home owner and complete handyman idiot.
