ABSTRACT:
A drywall finishing system for finishing 1) normal inside and outside corners of any angle, 2) stub wall or closet corners, 3) window wrap corners, and 4) L-metal for window sills and areas where drywall ends against some other surface like brick. The finishing system comprises a preformed trim piece comprising a semi-rigid member that is relatively thick in the center and tapers laterally to a thin edge. A layer of paper is bonded to the inside surface of the semi-rigid member for receiving joint compound to continuously bond the trim piece to the dry wall. A layer of finishing material is bonded to the exterior surface of the semi-rigid member. To install one of the pieces, it is selected from stock and cut to length. A flat coat of mud is applied to both sides of an exterior or interior angle, and the trim piece is placed over the mud and smoothed into place. Since it is preformed, the piece makes a straight line at the required angle. Once, the piece is in place, the edges are feathered once with a small amount of mud and a wide blade. At that point the corner is complete except for drying. It generally does not need to be sanded or touched up or at most, requires very little sanding or touching up. The finish material on the exterior surface can be directly textured or painted. Most of the intense labor associated with prior art methods is eliminated since none of the parts need to be coated with mud or sanded. In addition, the parts form straight, finished lines and angles as soon as they are installed.
