I have a living room that I am looking to update. It currently has 1/4" Wall Paneling over 3/8" drywall. The drywall is in very good shape, but has not been taped. The house is from the 50's, so they used nails to attach the drywall to the studs. Those now have a layer of rust on them.
I could just tape and mud, but I am worried about the drywall being too thin. My other consideration is to put another layer or 1/4" over it. This would cover over the rusted nails, which have a tendency to pop, and give me a cleaner wall. If this is the recommendation I was also considering what attachment method: drywall adhesive or screws?
P.S. The room is getting new windows, so those will be adjusted as needed.
