Abstract: A drywall trimming element for bridging two sections of drywall is an extruded element having first and second opposing flanges each having an interior surface and an exterior surface. The element is secured to the drywall by joint compound. The interior surfaces are adapted to be positioned on or adjacent to a respective one of the drywall surfaces. The interior and exterior surfaces each define respective surface planes. One or both of the interior and exterior surfaces have a plurality of upstanding longitudinally oriented ribs extending outwardly from the surface. The ribs extend away from their respective surfaces and define a void space between the surface adjacent to the ribs and an end of the ribs, such that a line extending outwardly from and normal to the surface of the flange adjacent to the ribs traverses through the void space and then subsequently contacts the ribs. The void space serves to provide a joint compound locking feature for the trimming element.

Abstract: A container is provided having a periphery and a base, which enclose a cavity. The periphery and the base are connected together, the periphery upwardly extending from the base. The periphery has a first slot and a substantially opposing second slot. Each of the first and second slots is sized to permit a first end of a tape located on a roll to be slid through it. A tape holder may be connected to the container so that the tape holder lies outside of the cavity of the container. The roll of tape can be placed on the tape holder so when the tape is pulled through the “mud box”, the tape is thereby unwound. As the tape is manually pulled through the “mud box”, joint compound is thinly applied to one side of the tape. As this is done, the joint compound begins to “adhere” to the tape, conditioning the tape for excellent wall adhesion.

Abstract: A butt joint hanger (30) includes a central elongated rail (32) and two support elongated rails (34, 36) positioned on either side of the central rail (32). One or more U-channels (38) interconnect the three rails (32, 34, 36) at pivoting attachment points (40). The butt joint hanger (30) is inserted between two construction beams (94, 96) and the butt ends (108, 114) of two sheets of wallboard (104, 112) are attached to the central rail (32) by means of drywall screws (110). The two support rails (34, 36) abut against the surfaces of the wallboard flush with the nailing surfaces (98, 100) of the construction beams (94, 96) and the drywall screws (110) force the butt ends (108, 114) of the wallboard out of the plane (102) of the wallboard and into engagement with the central rail (32). This results in a depression area (116) adjacent both butt ends (108, 114) which can be easily filled with plaster (122) to produce a flat smooth butt joint (126).

Abstract: A back-blocking device and method designed to attach any thickness of drywall together at the butt ends of the panels. Butt seams are necessary because of larger ceilings and walls where using one length drywall panels is impossible. Using conventional techniques, butt seams are difficult to conceal and are subject to ridging. This device and method enables the joints to be made between the framing members by securing each end to a specially designed back-blocking. This union creates a joint that attaches the panels together, basically creating a continuous piece of drywall. The back-blocking is slightly angled down the center, at an angle of approximately 170 degrees.
