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; this paper layer can optionally have a layer of adhesive material on its outer surface. A layer of finishing material is bonded to the exterior surface of the semi-rigid member.

Abstract: A boxable corner bead for finishing drywall corners that is made from two flanges with a protruding nose section. This bead can be made in regular, bullnose, or flex trim type arrangements. Once the bead is attached to a drywall corner, it can be mudded on both sides of the corner without waiting for the mud on the first side to dry. This is because of the shape of the nose which allows a mud dispensing box to apply mud on one side without getting mud on the nose. The box can then be immediately moved to the other side, where that side can be mudded. The nose itself is prepared to directly receive paint or texture, and hence does not need any mud. A version of the device has a raised trapezoidal, triangular or bull-nose section with a V-groove cut in the back. The bead hinges around the V-groove to match any corner angle. Both sides can be mudded as with the fixed bead. The beads can be used with both interior and exterior corners.

Abstract: A non-slip, nocoat drywall finishing system for finishing inside and outside corners of any angle, the finishing system being a pre-formed, continuously extruded trim piece comprising a semi-rigid member that can be relatively thick in the center and tapers laterally to a thin edge. An outer finishing layer of fibrous material that directly receives paint or texture. A pattern of protrusions, ridges, or grooves on the inner surface of the semi-rigid member to avoid the need for an inner material layer. 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. 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.

Abstract: A drywall finishing system where a continuously extruded, elongated semi-rigid member with an inner and outer layer of fibrous material has a groove running end-to-end allowing the piece to assume any angle to match a drywall seam. The groove is held at a fixed angle near 89 degrees (or any other fixed angle) by a break-apart bead running in the groove. The break-apart bead can be glue or extruded plastic or other means that holds the flanges at a rigid angle. If the seam is a right angle, the piece is used without breaking the bead. If the seam is any other angle, the break-apart bead is snapped or cut apart allowing the flanges to assume any angle.

Abstract: Drywall endcaps of the type that mate with drywall seam finishing material. The endcaps can be square or bullnose and cap the ends of exterior corners with either three 90 degree or other exterior angles, or two 90 degree or other exterior angles and one 90 degree or other interior angle. The endcaps can be made of two or three laminate layers with an inner layer that faces wallboard and a rigid or semi-rigid layer that can be optionally tapered. The semi-rigid layer can be high impact plastic. An optional outer layer is of fibrous material and is prepared to directly receive paint or texture.

Abstract: A drywall finishing system for inside and outside drywall corners including regular corners and bullnose corners. A special roller tool with a flexible frame and four rollers is used to press prefabricated drywall trim into place over a coating of drywall mud. Embodiments for inside and outside corners differ in that the rollers for inside corners are opposed and those for exterior corners are open, in both cases forming an angle of 84 to 87 degrees but able to flex from 84 degrees to over 97 degrees to match an corner angle. A special edge finisher mud box then allows the tapered edges of the trim pieces to be feathered and brought to a finished state. The mud box has several different front slots for coarse and final feathering.

Since it is preformed, the piece makes a straight line at the required angle.

Abstract: An adjustable pre-fabricated 3-way inside drywall corner with two flat sides and a flat face to be placed in the pointed 3-way corners created where sheets of hung drywall are joined to form two walls and a ceiling. This pre-fabricated corner can be paper, metal, or other suitable material. It allows a drywall worker to string tape by starting the tape a few inches away from a corner and running to the next corner, ending a few inches away from the second corner. The worker thus does not have to gauge exactly where to cut the tape to mate into the corners. Also, the effect of tape slip while stringing becomes unimportant. After the tape and drywall mud is dry, before the finishing step, the pre-fabricated corners are placed in every corner of a room, held in place by drywall mud. A drywall worker needs only to put a small amount of topping mud on the flanges and then "kill" the corner with a 4-6 inch knife.
