A systematic procedure, plus a series of (palm of the hand sized) perforated steel plates, for permanently repairing cracks, joint separations, impact holes, and other such damages, in gypsum wallboard panels. Repairs can be made with little or no rearward connection or support from the framing studs or joists at any desired position along the wall or ceiling framework. The invention is comprised of one Primary Steel Plate, plus a reusable hand-held tool for its installation. There are two other uniquely designed steel plates, each one for specific types of cracks or panel separations. The hand-held installation tool creates a pivoting action hinged installation assembly when joined with the primary steel plate; which may be folded on its "Hinges" like a jackknife and inserted directly through the crack or separation. It is then pulled flush against the inner panel surface. Once in place, it may be blind fastened from the outer panel surface with drywall screws; thereby creating a permanent mechanical bond and an artificial backing between broken or separated panel edges. The hand tool is then released to be used to install multiple plates as needed. All completed repairs receive final bonding with joint compound and tape, followed by match texturing and painting.
