Abstract
A repair device which is used to restore planarity to concave damage in a drywall board, which is quickly installed by chucking to a reversible power driver in the manner of a drill bit, thus creating its own hole. The device is inserted into the wall cavity, then powered in the reverse direction to actuate in the manner of a jack to push out a damaged drywall piece, which is still hingedly attached by the cardboard facing. Thus united, the cracks are bonded with cement, while the inexpensive device remains inside the wall, acting as a permanent prop.
