Abstract

The within inventive method for repairing a drywall surface (i.e. gypsum boards) or a plaster wall or ceiling, obviates the need for spackling and contemplates instead the use of a plastic film in covering relation over the surface defect and in this position properly prepared, so that the plastic is totally devoid of wrinkles and in firm attachment to the surface, with the result that the repair cannot be detected from the original surface.
