Abstract:

Plaster core laminated wallboard is repaired or finished with a repair article comprising a substantially rigid steel plate having integral teeth forcibly insertable into the wallboard to hold the article in place over the damaged area, and a flexible cover portion formed of wallboard facing paper overlapping the edges of the plate and bonded thereto. The thickness of the paper cover portion may be tapered toward the outer edges thereof to form a smooth transition from the cover portion to the existing wallboard surface. Holes in the plate near the edges or corners thereof provide for increased contact of wallboard repair compound with the paper cover portion. The article may be formed in different configurations for covering plumbing openings, exterior corners and elongated stress cracks or seams. The wallboard is repaired by cutting a recess into and through the paper surface lamination of said wallboard to the outline of the plate portion of the repair article. The facing paper layer of the wallboard may also be cut to the outline of the cover portion of the repair article to provide for recessing the cover portion also.
