I have a older home, 1920's and little has been done. Until recently, the upstairs was closed off, and realized the old plaster and lathe is crumbling. Can you just drywall over it? I was thinking of getting a contractor, but wondering the cost. Was looking at the cheapest and easiest way. The painting and taping I can do, just concerned with condition of current walls. There are 2 rooms, 10 x 10 and a stair way going up stairs, all done in plaster and lathe with the popcorn paint.
Any help or advise would be greatly appreciated.
Installing new drywall sheets over top of the plaster is the best solution. I would not recommend coating the old plaster with mud to repair or add on anything. This tends to cause the plaster to let loose with the renewed moisture and fall off in large clumps. It is very difficult to fix old plaster in this manner.
