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.

An automated drywalling system network that including one or more automated drywalling systems that each has a robotic arm. The automated drywalling system network can also include a computational planner that generates instructions for the one or more automated drywalling systems to perform two or more drywalling tasks associated with a target wall assembly. The two or more drywalling tasks can include a hanging task that includes hanging pieces of drywall on studs of the target wall assembly; a mudding task that includes applying joint compound to pieces of drywall hung on studs of the target wall assembly; a sanding task that includes sanding joint compound applied to the pieces of drywall hung on studs of the target wall assembly; and a painting task that includes painting sanded the joint compound applied to the pieces of drywall hung on studs of the target wall assembly.

A metal hand tool including a handle attached to a blade piece and method of construction. The blade piece includes a blade opposite an elongated tang. The handle is made up of two, welded, symmetrical handle halves, each handle half having an opening for receiving a hang hole piece and a notched distal end for forming a handle opening to receive the blade piece elongated tang. In an embodiment, the handle includes a curved distal end accommodating a curved welded connection between the blade piece and the handle. The hand tool further includes a hang hole piece configured for placement through the hang hole openings in the handle and for welded connection to the handle. In an embodiment, the elongated tang includes a hang hole opening through which the hang hole extends. Some embodiments further include one or more tang guide pieces welded to the interior of the handle.

A drywall knife holster includes a belt hook, a back member and a knife holder. The back member couples with the belt hook. The knife holder couples with the back member through an upwardly facing U-bend that biases a pinch region of the knife holder toward the back member. Inserting a drywall knife blade between the knife holder and the back member, and seating a leading edge of the drywall knife blade within the U-bend, causes the pinch region of the knife holder to urge a handle of the drywall knife into contact with the back member. The back member and the knife holder may form a holster portion that couples with the belt hook through a swiveling connector. The holster may continue past the pinch region to form a second drywall knife holder and/or a loop member to accommodate a different tool.

A versatile compound tool for forming wall board compounds comprises a handle assembly having a handle along a first end and an extension along the second end. The extension along the second end of the handle assembly further includes a connection feature for selectively securing a first implement thereto, the first implement configured for performing a first function of forming wall board compounds. The versatile compound tool further comprises one or more subsequent implements selectively securable to the second end of the handle assembly for performing second and additional functions of forming wall board compounds.

A simple, hand-held tool for applying drywall compound or other spackle type cement or adhesive substance into a tight space through the entire length and height of the space, such as in a corner next to molding or other obstruction. The device as described may be fashioned in various widths at its applicator end to accommodate various widths of such spaces.

An applicator for dispensing a viscous material from a container. The applicator comprises a nozzle for fluid communication with the container. The nozzle has an outlet at a first end and base in proximity to an opposed second end. The nozzle further includes a support arm spaced apart from the nozzle. The support arm and the nozzle collectively forming a slot therebetween for releasably receiving a blade. An attachment portion extend from the base and is configured to releasably engage the container to permit material within the container to flow under pressure through the nozzle and onto a surface. When the blade is received within the slot, it contacts the material as it exits the nozzle and assists in forming the material into a desired shape or configuration.

Described herein is a method of using an adhesive article on a gypsum board construction assembly. The gypsum board construction assembly has a first gypsum board unit and a second gypsum board unit defining a space therebetween, the method comprises obtaining the adhesive article, wherein the adhesive article comprises a first major surface and an opposing second major surface, wherein an adhesive is disposed on the first major surface and the opposing second major surface has a surface free energy of at least 29 mN/m, and wherein the adhesive article has an adhesion to gypsum board of at least 45 oz/in (0.49 N/mm); and fixedly attaching the adhesive article via the adhesive to a first and second attachment areas, wherein the first gypsum board unit comprises an outer paper surface and the second gypsum board unit comprises an outer paper surface and the first attachment area is on the outer paper surface of the first gypsum board unit and the second attachment area is on the outer paper surface of the second gypsum board unit, and wherein the portion of the adhesive article disposed over the space is non-porous.

The present invention relates generally to wall repair compounds such as joint compounds, spackling compounds, and the like used to repair imperfections in walls or fill joints between adjacent wallboard panels. Particularly, the present invention relates to such a wall repair compound that comprises a dust-reduction additive that reduces the quantity of airborne dust generated when the hardened compound is sanded. The dust-reduction additive also synergistically imparts water resistance and adhesion to the wall repair compounds to which it is added. More specifically, in one embodiment, the dust-reduction additive is an emulsion comprising colloidally-protected, wax-based microstructures comprising paraffin that is chemically encapsulated by polyvinyl alcohol.
