A level marking device for drywall installation is disclosed herein. In one embodiment, the level marking device includes a body portion configured to be attached to a carpenter's level; and a pin member coupled to the body portion. In another embodiment, the level marking device includes a carpenter's level, the carpenter's level including a body portion and a level indicator for establishing a horizontal and/or vertical line or plane; and a pin member coupled to the carpenter's level. The pin member of the level marking device is configured to be positioned at the intersection of one side of a stud and an edge of drywall. The level marking device is configured to position one edge of the carpenter's level approximately aligned with a centerline of the stud so as to enable a guide line to be marked on the drywall that approximates the centerline of the stud.

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 support tool for installing tiles onto a wall above a niche in the wall provides support for tiles being mounted above the niche. The tool includes a support plate configured to be secured to or braced against an upper surface of the niche. A tile support bar supporting lower edges of the tiles may be adjusted and held in a selected vertical position relative to the plate, so that lower edges of tiles may be placed in a desired vertical position relative to the upper surface of the niche. The tile support bar may be slidably supported on a support rod in a selected position by a nut threaded onto the support rod. The tool may be secured in position by screwing the support plate onto the upper surface of the niche, or by bracing the tool in place using a length-adjustable extender assembly.

A siding installation gauge includes a tool body, an upper support member, a clamp, and an actuating mechanism. A clamping portion of the clamp is inserted behind an installed lower siding board and the tool actuated to secure the lower board between the clamp and tool body. An upper siding board rests on registration surfaces on the upper support member while it is fastened for installation. The clamp includes coupling and clamping portions; movement of the actuating mechanism to an actuated arrangement retracts the coupling portion into or through the tool body and thereby forces movement of the clamp toward the tool body to secure the lower siding board. In the actuated arrangement, the actuating mechanism retains the clamp in a clamped arrangement; in the non-actuated arrangement, the actuating mechanism permits movement of the clamp into a non-clamped arrangement.

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.

Disclosed are a ceramic tile leveling bracket, pushing and clamping pliers, and a ceramic tile leveling and laying system. The ceramic tile leveling and laying system comprises: a ceramic tile leveling bracket, an insertion block, and pushing and clamping pliers, wherein the ceramic tile leveling bracket is disposed at a junction of at least two adjacent ceramic tiles, one end of the insertion block is inserted into an insertion block receiving portion of the ceramic tile leveling bracket, and the pushing and clamping pliers push and clamp the insertion block into a ceramic tile leveling bracket such that a bottom face of the insertion block is tangent to upper surfaces of the ceramic tiles. The ceramic tile leveling and laying system is easy to operate, and improves the laying efficiency and laying quality.
