A method of generating a building assembly that includes spraying a coating material onto a plurality of pieces of substrate disposed on a first assembly face. The spraying includes spraying the coating material onto the plurality of pieces of substrate via a sprayer configured to apply the coating material to a target surface via a nozzle coupled with a mobile storage container storing the coating material, the coating material impregnating voids of the substrate. The method also includes allowing the coating material impregnating the voids to dry and harden and become rigid to generate the building assembly.

An application head for an applicator for applying jointing tape between two plaster boards includes a fixing core and two sides receiving two rotation shafts parallel to each other, two notched rollers being carried by the first rotation shaft, and two link rods being mounted so as to be able to pivot on the second rotation shaft, one end of each link rod being mounted so as to be able to rotate freely on a third rotation shaft, to either side of a corner roller. The application head also includes a spring comprising two legs bearing against the fixing core, extended by an elbow linked to a blocking arm provided with a notch for immobilizing the link rods in the use position, the blocking arms being linked together by a return hoop and reversible blocking mechanism for immobilizing the link rods in the retracted position, separate from the spring.

The invention relates to a strip applicator (1) for ensuring the joint between two plaster boards. The applicator comprises a coating container (4) wherein a strip unwinds in use, the container having a rear wall, a bottom wall, a front wall, a top wall and two side walls, one of which forms a removable side cover for accessing the inside of the container. According to the invention, the lower wall comprises an opening (14) provided with a removable plug (15) for accessing the inside of the container, the opening being directed towards the upper wall of the container.

A system for finishing surfaces with a finishing material includes a handle assembly with proximal and distal ends. A material reservoir is mounted on the handle distal and includes an inlet and an outlet. A material applicator tool is mounted on the reservoir and receives material from the reservoir outlet. A discharge mechanism includes an extendable-retractable component or linear actuator connected to the reservoir for discharging or reloading material. Multiple embodiments utilizing different linear actuators are disclosed. An alternative embodiment includes a push-to-open valve mechanism. Additional embodiments include an adjustment mechanism on the push-to-open valve mechanism accommodating adjustment of flow of finishing compound when the push-to-open valve is engaged.

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.

A tool for cleaning a tile bonding compound from between and on a plurality of adjacent tiles includes an elongated handle and a tool head fixed with the handle. The tool head is comprised of a first tool and a second tool. The first tool includes a foam scrubber and a seam scrubber or wiper. The second tool includes at least one arcuate elastomeric wiper and a seam wiper. Both the foam scrubber and elastomeric wiper are adapted for scrubbing the tile bonding compound from a front face of the adjacent tiles, while the seam scrubber and seam wiper are adapted for fitting between two of the adjacent tiles to scrub the tile bonding compound from between the tiles.
