Laminate and method for drywall holes and joints

Claim 2

A preformed laminate structure for finishing or repairing operations on previously installed drywalls comprising a single backing member made from thin sheet material shaped to cover a selected area of previously installed drywall to be finished or repaired and a body portion made from a thin layer of rigidified plaster-like material adhered on one side to a front face of said backing member and having an opposite uncovered side providing a surface for receipt of a finishing compound thereon, said body portion having its greatest thickness in the inner portion thereof and with said thickness tapering toward at least one edge portion thereof to a minimum thickness with at least some of the minimum thickness portion thereof spaced from an uncovered edge portion of said sheet material to provide a flat surface on such uncovered edge portion of sheet material for receipt of finishing compound to blend with the adjoining tapered body portion to hide said edge portion and its edge in the finished work.

Claim 3

A laminate structure as claimed in claim 1 wherein said structure is circular in form and said inner body portion tapers from the center thereof toward the circumference of the structure leaving a marginal circumferential edge portion of exposed sheet material of substantially uniform width.

Claim 4

A structure as claimed in claim 1 including an electrical outlet shaped opening formed therein and through said body portion.

Claim 5

A structure as claimed in claim 1 having selected aligned linear edge portions of said backing member and body portion formed and adapted to rest against a mating linear edge in the building construction receiving said structure.

Claim 6

A structure as claimed in claim 3 having selected aligned linear edge portions of said backing member and body portion formed and adapted to rest against a mating linear edge in the building construction receiving said structure.

Claim 7

A structure as claimed in claim 1 wherein said structure is formed as a right angular member of sufficient length to cover the area desired to be finished or repaired, said right angular structure having said body portion tapering outwardly from the apex of said right angle structure leaving an uncovered marginal edge.

Claim 8

A structure as claimed in claim 6 including a right angle metal reinforcing member secured to the outer back face thereof.

Claim 9

A structure as claimed in claim 1 wherein said backing member is rectangular in form and said body portion maximum thickness coincides substantially with the central axis of said backing member, said body portion having a rectangular form with the outer peripheral lengthwise running edges of said body portion being spaced uniformly inwardly from the lengthwise running edges of said backing member.

Claim 10

A preformed laminate structure for finishing or repairing operations on previously installed drywalls comprising: (a) a backing member made from thin sheet material and having an area shaped to cover the area to be finished or repaired; (b) a body portion made from a thin layer of rigidified plaster-like material adhered on one side to a front face of said backing member and having an inner portion of greatest thickness and with said greatest thickness tapering toward and terminating at a predetermined distance from outer uncovered flat edge portions of said backing member; and (c) a facing member made from thin sheet material and shaped to cover the surface of said body portion opposite said backing member, said facing member being adhered to said body portion on one side and having the opposite side uncovered to provide in conjunction with said uncovered edge portions of said backing member adjoining respective covered tapered and uncovered flat surfaces for receipt of a finishing compound to blend with said tapered body portion and hide said edge portions and the edges thereof in the finished work.

Claim 11

A preformed laminate structure for finishing or repairing operations on previously installed drywalls comprising: (a) a backing member made from thin sheet material and having an area shaped to cover the area to be finished or repaired; (b) a body portion made from a thin layer of rigidified plaster-like material adhered on one side to a front face of said backing member and having an inner portion of greatest thickness and with said greatest thickness tapering toward and terminating at a predetermined distance from outer uncovered flat edge portions of said backing member; and (c) a facing member made from thin sheet material and shaped to cover the surface of said body portion opposite said backing member, said facing member being adhered to said body portion on one side and having the opposite side uncovered to provide in conjunction with said uncovered edge portions of said backing member adjoining respective covered tapered and uncovered flat surfaces for receipt of a finishing compound to blend with said tapered body portion and hide said edge portions and the edges thereof in the finished work.

Claim 12

A laminate structure as claimed in claim 9 in strip form and wherein the linear edges of said body portion and facing member terminate at a uniform distance from the linear edges of said backing member.
