Abstract
A repair method which is used to restore planarity to concave damage in a wall of gypsum board construction, wherein the device is inserted through a small hole drilled in the damaged area, or inserted from the rear through a hole drilled in the back wall. Features of the device engage the opposing interior surfaces of the two wall boards. Tears and cracks in the wall are cemented. The device is manually powered in the manner of a jack to push out the damaged board pieces, which are still hingedly attached by the cardboard facing. Thus united, the cracks are bonded while the inexpensive device is left in the wall, acting as a permanent prop. Remnants of the device remaining outside of the wall are broken off and the hole is filled.
