Abstract: A boxable drywall corner trim including an elongated semi-rigid member that forms a pair of flanges joined at a grooved hinge along a centerline. Each of the flanges can have a thinner part and a thicker part joined at a step that is approximately parallel to the centerline a predetermined distance from the centerline. The thicker part of the flanges can form a protruding nose member that makes the piece boxable by preventing the cross-over of wet drywall mastic or mud from one flange to the other. The thinner portion of the flange may optionally be perforated with a pattern of punched holes of any configuration throughout the flange assembly. The piece can have a wall-facing paper or other fibrous layer of material that has a tacky adhesive on its wall-facing side. The adhesive can be in a pattern of dots, ridges, lines or any other pattern, or the adhesive can be continuously coated on the surface.

A first aspect relates to an aperture edging member for forming a substantially smooth or “flush” aperture within a surface member. The edging member includes a substantially planar rim portion adapted to be attached to the surface member, a lip provided along one edge of the rim, and a flange depending from the lip in a substantially transverse direction to the rim so as to fit within the aperture. The second aspect relates to an aperture edging device which has an intermediate section with a pair of arms depending transversely therefrom to form a substantially c-shaped configuration to envelope the edge portion of the surface member. An advantage is that a strong rigid vertical face is created in the plaster board, minimizing the possibility of damage thereto. Light fittings, or other fittings may be associated with the device.

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. The flex-trim version has a raised trapezoidal 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.

Adhesive is then applied to the rearward surfaces, and the assembly of the corner device and the panels is adhered to a building structure.

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.

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 corner bead includes an elongated strip of plastic material with a central arcuate nose and a pair of flanges extending outwardly from the nose. The outward faces of the flanges have knurling formed thereon, to retain joint compound in place during dressing of the corner. In the preferred form of the invention, the knurling is in the form of diamond-shaped depressions formed uniformly across the length and width of the flange outward faces. The method of forming the knurled surface in the bead includes the step of forming separate depressions in an outer face of a flange of the bead immediately after the extrusion process, prior to the material cooling.

Abstract: A strip of polymer material is used as a corner bead or drywall tape. In a preferred application, the location, i.e. a joint, where two pieces of drywall meet are sprayed with an adhesive and the strip is put in place over the joint. Then, drywall compound is placed over the strip and finished by a drywall finisher. Perforations, depressions and knurling on the strip allow drywall compound to form, when dry, a mechanical bond to the strip at the joint. The material used to make the strip is preferably a mineral filled polymer, such as talc-filled polypropylene, which is inexpensive and lightweight. The adhesive applied to the joint is preferably one which is specially formulated to bond to polypropylene. The strip is initially extruded into a flat form and a crease is imparted to the center of the strip. This allows the strip to be carried in a compact, rolled form.

If the seam is any other angle, the break-apart bead is snapped or cut apart allowing the flanges to assume any angle.
