  • Patent number: 10577811
    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.

  • Patent number: 10532332
    Abstract: A continuous ready mix joint or texture compound manufacturing system and a method for continuously manufacturing a ready mix joint or texture compound includes a continuous mixer having an inlet and an outlet, a pump disposed at the outlet of the continuous mixer, and a disperger having an inlet and an outlet. The continuous mixer is adapted to receive at least one dry ingredient and at least one wet ingredient at the inlet and continuously mix the at least one dry ingredient and the at least one wet ingredient to form a mixed composition. The pump is adapted to pump the mixed composition from the outlet of the continuous mixer to the inlet of the disperger. The disperger is adapted to receive the mixed composition and apply a shear force to the mixed composition to form a homogenized, disperged composition.

  • Patent number: 9169426
    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.
