Abstract: A method is disclosed for the repairing of extensive damage to plasterboard areas wherein wet plaster will normally not hold in such a large repair area. The method includes the cutting through the paper surface layer of the plasterboard material in an approximately circular shape around the damaged area. The exposed plaster of the plasterboard can then be sanded by such a tool as a power rotating sander such that the plaster within the plasterboard is removed to a predetermined depth. A plate member having a thickness less than this predetermined dimension and preferably on the order of 0.014 inches is then placed over the damaged area within the removed plaster area. This plate member is fixedly secured to the undamaged area of the plasterboard within the defined circular area. The plate member is preferably perforated throughout for ventilation and securement of plaster thereto.
