A levelling spacer device for laying slab-shaped products including a base having a lower surface and an opposite upper surface defining a support plane for at least two tiles placed side by side, which is placed at a first distance from the lower surface, a spacer bridge provided with two legs placed side by side between each other along a flanking direction and each one rising from a portion of the opposite upper surface. Each leg is frangibly connected to the respective base portion by a predefined fracture line placed at a second distance from the lower surface greater than the first distance. A crosspiece, joins the top of the two legs, and a through opening peripherally delimited at the top by the crosspiece, laterally by the legs and at the bottom by a central portion of the upper surface coplanar with the support plane.

A tool for applying a binding agent and/or a filler is provided. The tool enables convenient and accurate application of the binding agent and/or the filler, such as adhesive or mortar for wall panels and grout between wall panels. The tool comprises a body including a front surface, a rear surface, and a plurality of edges circumferentially extending around the body, each of the plurality of edges defining a junction of the front surface and the rear surface. One of the plurality of edges comprises a plurality of teeth extending away from the body. The teeth may comprise a flat face. One of the plurality of edges may comprise a protrusion. One or more rounded corners may be circumferentially disposed around the body between two proximal edges.

A mortise jig assembly includes a block that is longitudinally elongated. The block has plurality of mortises therein and the block is clamped to a face of a door such that selected ones the mortises is aligned with an edge of the door. A jig panel is provided and the jig panel is positionable against the edge of the door to engage respective ones of the mortises thereby retaining the jig panel at a selected location on the edge of the door. The jig panel has a guide hole therein thereby facilitating the guide hole to be aligned with a preferred location to cut a hinge recess in the edge of the door. A pair of bolts is each extendable through the jig panel and the block for attaching the jig panel to the block.

An automated painting system that includes a robotic arm and a painting end effector coupled at a distal end of the robotic arm, with the painting end effector configured to apply paint to a target surface. The painting system can also include a computing device executing a computational planner that: generates instructions for driving the painting end effector and robotic arm to perform at least one painting task that includes applying paint, via the painting the end effector, to a plurality of drywall pieces, the generating based at least in part on obtained target surface data; and drives the end effector and robotic arm to perform the at least one painting task.

A framing accessory includes a bead and a backing strip. The bead may comprise a first leg, a second leg, and a lip. The second leg may comprise a plurality of openings. The strip may be attached to the upper surface of the first leg. In some embodiments, the strip may comprise a single layer of material, while in other embodiments, the strip may comprise two or more layers of material. The strip may comprise material having fire resistant, intumescent, and/or sound insulating properties. The finishing accessory may be configured to be installed in a gap at a head of wall joint by positioning the first leg and strip along the top edge of a wallboard panel and the second leg extending vertically downward along the outer surface of the wallboard panel.

A method for laying tiles or other coating elements where a separator is placed under, above and between adjacent tiles during the process of cementing the tiles to a surface. The method includes: placing a metal rod of a one-piece tile separator between two adjacent tiles, with a metal base part under adjacent tiles, sliding a tile holder onto the metal rod, where one-way steel jaws opposite each other in the tile holder are pressured towards two opposed smooth surfaces of the metal rod, preventing return movement of the tile holder along the metal rod while the opposed one-way steel jaws indent the softer metal surface of the metal rod.

A decorative layer removal tool for flooring is configured with a removal shaft and either a drill attachment or handle to remove the decorative layer from a plank. The removal shaft includes a threaded end to attach to either the handle or drill attachment. The handle can be used when the user wishes to manually rotate the shaft and remove the decorative layer; the drill attachment can be used with a power drill for a motorized removal. The removal shaft includes a slit that extends from an unthreaded end to the threaded side. In typical implementations, the slit may not extend to the shaft's threads. At least a portion of the slit is used to receive the decorative surface layer from a plank, thereby enabling the decorative layer's removal.

A tile aligning and leveling system that uses an under tile base re-usable upright connecting tab, which is detachably connected to said under tile base, a re-usable flexible edge slotted cap configured to slip over the connecting tab and latch thereto as the cap is slid further down the connecting tab. The cap has an edge slot so that the connecting tab can be separated from the cap, by merely sliding the cap, so that the connecting tab passes through the slot. A flexible spring-like portion of the cap provides increased force on the tile even if undesired elongation of the connecting tab occurs.

Example aspects of a fenestration-lowering device and a method for using a fenestration-lowering device are disclosed. The fenestration-lowering device can include a frame; a support platform configured to move relative to the frame; and a hydraulic lowering mechanism configured to move the support platform. The method for using the fenestration-lowering device can include providing a hydraulic lowering mechanism for moving a support platform of the fenestration-lowering device from a raised orientation to a lowered orientation; setting a fenestration product on the support platform in the raised orientation; activating the hydraulic lowering mechanism to move the support platform from the raised orientation to the lowered orientation; and removing the fenestration product from the support platform.
