Method and apparatus to repair holes in walls comprising a perforated flexible plate adapted to be inserted through the opening in the wallboard of the wall, the flexible plate having a peripheral edge coated with adhesive to engage and attach against the inside surface of the wallboard around the opening therethrough. Located generally central to the flexible plate is a transverse threaded screw, the threaded screw adapted to hold in the opening in special alignment between the opposite sides of the wallboard, perforated resilient plate or metal lath plate attached to the transverse threaded screw by means of a nut affixed to the plate or by means of opposing nuts with the plate therebetween. The perforated resilient or metal lath plate utilized is sized to be slightly smaller than the opening in the wall. The perforated flexible plate is sized to be slightly larger than the opening in the wallboard. The opening in the wall, now having metal lath located centrally thereto, is filled with repairing material, nominally plaster or grout, to a point where it bulges slightly over the flat surface of the surrounding wall. The repairing material is allowed to dry, and upon complete drying, is sanded away until a flat continuous surface is achieved between the wall and the patch. The surface is then painted with a matching colored paint.

Apparatus to repair holes in walls comprising a flexible perforated plate adapted to be inserted through the hole in the wall and to attach to the inside surface of the wall proximate the hole; a threaded screw attached transversely to the flexible perforated plate; and a perforated resilient plate attached to said transverse threaded screw by means of at least one nut threaded on said screw and operably connected to said perforated resilient plate, said perforated resilient plate situated spacially in the hole of the wall whereby the hole in the wall is filled with plaster to the thickness of the wall with the plaster completely surrounding and penetrating the perforated resilient plate which serves to retard shrinkage of the plaster from the hole in the wall and to enhance resistance to chipping of the plaster.
