We are installing new kitchen cabinets in our 1930s home. The plaster beneath the old cabinets is cracked and crumbly on a few walls that will hold the much heavier 42" solid cherry wall cabinets. One wall is an exterior bricked wall without studs. Another is terra cotta block - again with no studs. The plaster appears to adhere to metal mesh rather than lathe in these areas.
Our trusted electrician insists that the kitchen contractors should take out the plaster and replace with drywall. Our kitchen contractors (with whom we've never worked before) say that mounting screws for the cabinets cannot be safely sunk into the brick or terra cotta. They have cautioned against screwing or gluing a veneer of dry wall over the old plaster as well, stating that our cabinets would no longer fit properly into the two corners where our stove and sink will be relocated.
Each party's argument is equally convincing. I am not knowledgeable enough to determine which one I should listen to.
