Approx the bottom half of a 5 x 12 palster wall has to be repaired/replaced. The thickness between the lathe and the top coat ranges from just a hair under 1/4" to a hair over 3/8". A recent patch job i did with drywall revealed the same problem and it took a week to blend properly. Am I better off cutting the lathe out to reveal the studs and drywalling over that? If so, would I use furring strips of some kind to get the proper depth?
