The upstairs of my house was remodeled before I bought it. The whole house used to be plaster and lath but the upstairs is now drywall. The upstairs drywall has needed some minor repairs ever since I've moved in.
What I've noticed is that the majority of the blemishes that need to be repaired are nails. It is as though the nails are popping the joint compound off the walls and ceiling. Further, it looks like the drywall is actually held in with nails.
Is it common to attach drywall with nails?
Should I pull the nails and replace them with screws before fixing the blemishes?
