Abstract: An automatic dispensing device for wallboard joint taping is provided, including a body for holding a supply of viscous material and having a rear end and an opposite front end, a spool assembly disposed on the body and configured for supporting a spool of tape; at least one drive roller positioned at the front end and receiving an end of the spool of tape. Certain embodiments include an adhesive application assembly connected to the drive roller and mounted in operational relationship to the front end for dispensing a measured amount of adhesive upon an upper surface of the tape upon rotation of the at least one drive roll. In such embodiments, the body may be configured for holding sufficient adhesive to cover tape advanced by at least 200 rotations of the at least one drive roller.

Abstract: Disclosed are aspects of board finishing systems. For example, in various aspects, disclosed are joint compound compositions, wall assemblies, methods of treating walls, and products related to any of the foregoing, including reinforcement trim, e.g., for protecting corners where boards meet, fasteners, and tape. The joint compound preferably is a drying type composition with reduced shrinkage property, and includes binder and hollow spheres, resulting in an ultra lightweight formulation in some embodiments. The joint compound composition can be applied in a one-coat treatment in preferred embodiments. Other aspects of board finishing system accommodate such a one-coat treatment to thusly allow a user to manipulate the compound closer to the plane of board as compared with conventional formulations. Joint tape and reinforcement trim can include non-swelling synthetic paper facing material in some embodiments.

Abstract: Method of making foamed gypsum slurry having 15 to 90 volume percent gas bubbles including: passing first slurry including water and on dry basis 50 to 98 wt. % calcium sulfate hemihydrate, 1 to 50 wt. % calcium carbonate, and 0.1 to 10 wt. % cellulose thickener via a first hose to a Wye connector conduit first inlet opening at Rate C and passing alum solution via a second hose to a second inlet opening of the conduit at Rate D to create combined mixed stream passing from the conduit to a static mixer for mixing for Time 3 to activate at least a portion of the calcium carbonate and alum to generate CO2 and create the foamed gypsum slurry; transferring the slurry from the mixer to a cavity between two wall boards via a third hose. Allowing the slurry in the cavity to expand, harden and dry.

Abstract: A prefill tool for finishing wallboard joints is provided for finishing a wallboard joint, and includes a box assembly defining a hopper, having a top wall and a front wall constructed and arranged for engaging the wallboard joint. The front wall partially defines a gate dimensioned for dispensing joint compound stored in the hopper. Also, the gate is located on a skid plate mounted on the front wall, the skid plate having a main portion, and a gate portion partially defining the gate being displaced from a plane defined by the main portion.
