Abstract: An applicator for and method of applying a material, and a piston assembly for the applicator. A piston assembly of the applicator is movably engaged within a housing to form a reservoir that is expandable and contractable to, respectively, draw into and push out from the reservoir the material via an opening during, respectively, suction and pressure phases of the applicator. The piston assembly includes an outer seal to prevent ingress of fluid towards the reservoir from an outer side of the piston assembly during the suction phase and an inner seal disposed between the outer seal and the reservoir to prevent egress of material out of the reservoir into a cavity formed between the housing and the inner and outer seals, during the pressure phase. The outer seal moves freely as the applicator is moved to the pressure phase to open the cavity for pressure equalization to prevent suction.

Abstract: A drywall mud applicator tool includes a body having a wall engaging applicator face, a first end, a second end, a first side and a second side. A first wheel is mounted for rotation on an axle which is secured to the first side adjacent to the first end. A second wheel is mounted for rotation on an axle which is secured to the second side adjacent to the first end. A third wheel is mounted for rotation on an axle which is secured to the first side adjacent to the second end. A fourth wheel is mounted for rotation on an axle which is secured to the second side adjacent to the second end. A first mud containment skirt extends along the first side from the first end to the second end. A second mud containment skirt extends along the second side from the first end to the second end.

Abstract: A variable angle corner flusher tool includes a pair of blades pivotally connected along one edge. An activator assembly is provided to facilitate angular adjustment of the blades. The activator assembly includes an activator screw and a slider bracket that moves axially along the activator screw. A pair of linkage arms are provided, with each linkage arm having a first end attached to the slider bracket and a second end attached to one the pair of blades. The linkage arms results in an axial position of the slider bracket along the activator screw determining the angular positioning of the blades. A ratchet plate is pivotally mounted to the slider bracket. The ratchet plate is selectively pivoted between an engaged position engaged with the activator screw and a disengaged position disengaged from activator screw.
