The present invention, in some embodiments thereof, relates to a spreader for spreading paste (for example a tile adhesive) over a surface and more particularly, but not exclusively, to a system for pumping and uneven spreading of adhesive along a surface of a building. For example, the system may include a source of the paste optionally including a mixer, driver and/or conveyer. The paste may be driven to a spreader. For example, the spreader may deposit the paste unevenly over a surface. For example, the spreader may include multiple outlets and/or an uneven spreading blade (for example in the form of a comb). For example, the paste may be spread as lines across the surface.

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 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.

A jet adapter (1) for plastering machines is designed for (semi)automatic application of materials, such as plaster, heat insulation foam, penetrating agent, etc. onto walls Thanks to its design, this unique jet adapter (1) in combination with a smart plastering machine is capable of plastering 1 m of a standard wall in 3 minutes, including plaster trowelling. The application of material onto the wall is performed by especially designed material jets (2) comprising a jet channel (22) and at least two gas feeds (24) entering the jet channel (22) at the slope ranging from 20° to 60° with reference to the axis of the jet (2), which feed the jet (2) with pressurized gas, that in the jet (2) accelerates the supplied material and provides it with energy sufficient for leaving the jet (2).

A spray gun includes a gun body and valves configured to control flow of material and air through the gun body. A trigger is mounted to the gun body and is disposed relative to the valves such that the trigger actuates the valves in sequence to begin air flow and material flow. A sensor senses when the trigger is in an actuated state and the sensor causes a pump to begin pumping material to the spray gun. Release of the trigger causes the trigger to leave the actuated state. A detent mechanism holes the trigger in a detent state intermediate the actuated state and a resting state. The sensor does not sense the trigger with the trigger in the detent state. The trigger maintains the valves open with the trigger in the detent state.
