A method for applying a layer of curable material to a surface including the steps of: applying the curable material to the surface; positioning a trowel relative to the surface so that a plurality of first radial teeth of the trowel, extending from a working edge of the trowel, is in contact with the surface; and with the plurality of first radial teeth in contact with the surface, moving the trowel across the surface to spread the curable material across the surface at a constant thickness.

A method of texturing a wall or ceiling with non-acoustical joint compound by providing a collapsible bag having an opening at its top and is adapted to contain non-acoustical joint compound for forming a textured coating on the wall or ceiling and providing a spray nozzle having a low pressure input port, a joint compound suction port attached to the opening at the top of the collapsible bag, and an output port for spraying the non-acoustical joint compound. A low pressure stream of air from an air gun attached to the low pressure input port urges a small quantity of the non-acoustical joint compound to be sprayed out of the spray nozzle when the bottom of the collapsible disposable bag is raised above its top to either allow or force the joint compound to flow into the suction port and into the interior of the spray nozzle.

A trowel may include a main body including at least one working edge, the working edge including an edge radius, a plurality of radial teeth extending from the working edge, each radial tooth of the plurality of radial teeth including a radial edge and a tooth radius. A distance between the edge radius and the tooth radius at any point along the working edge is the same.

A transfer pump includes a drive module having electronic components and a fluid module not including electronic components. The drive module provides motive power to a pump of the fluid module to power pumping by the fluid module. A control module is configured to monitor operation of the transfer pump and control pumping by the transfer pump. The control module is configured to receive dosing commands from a user interface, recall a dosing parameter based on the dosing command, and cause the drive module to operate the fluid module based on the dosing parameter to cause the transfer pump to output a set volume of material.

An apparatus for cleaning drywall tools includes a structure supporting two tanks, one above the other. The lower tank holds a supply of rinse water that includes a water-clarifying agent. A water-pumping assembly pumps the rinse water from the lower tank for pressurized tool-rinsing above the upper tank, with the upper tank collecting the used rinse water. After mud has settled from the used rinse water, thereby resulting in a body of clarified rinse water disposed above the settled mud, an upper water-draining assembly on the upper tank drains the clarified rinse water back to the lower tank for reuse or removal. A user lowers an adjustable inlet on the upper water-draining assembly to a position within the body of clarified rinse water so that only the clarified rinse water drains, without the settled mud. The apparatus is preferably work-bench size in order to enable contemporaneous tool cleaning by two users.

A device (1) for smoothing filling or plaster compounds and/or for spreading them by rubbing, comprising a smoothing plate (2) with a smoothing side (3) and a fastening side (4), a handle (5) and a holding element (6) which connects the handle (5) and the smoothing plate (2) on the fastening side (4), wherein the holding element (6) has a fastening flange (7) for fastening the smoothing plate (2), and a handle-fastening section (8), is intended to be improved in such a way that the handle is connected to the smoothing plate in a particularly stable manner without the weight of the device and the manufacturing costs being substantially increased. This is achieved in that the fastening flange (7) has a multiplicity of holes (9) into each of which there protrude fastening bolts (10) which project on the smoothing plate (2), said fastening bolts being fixedly connected to the smoothing plate (2) on the one hand and being connected to the fastening flange (7) by means of a pressed connection on the other hand.

Methods and apparatus are provided for finishing a composite floor. The apparatus includes a grouting pan configured to be affixed to the rotating head of a finishing machine. The grouting pan has a planar bottom surface and curved sidewall. Grouting pans are rotated over a prepped surface such that the curved sidewalls trowel the mortar onto the rough composite surface and the bottom surface which is in contact with the prepped floor forces the mortar into the surface voids.

A method of texturing a wall or ceiling with non-acoustical joint compound by providing a collapsible bag having an opening at its top and is adapted to contain non-acoustical joint compound for forming a textured coating on the wall or ceiling and providing a spray nozzle having a low pressure input port, a joint compound suction port attached to the opening at the top of the collapsible bag, and an output port for spraying the non-acoustical joint compound. A low pressure stream of air from an air gun attached to the low pressure input port urges a small quantity of the non-acoustical joint compound to be sprayed out of the spray nozzle when the bottom of the collapsible disposable bag is raised above its top to either allow or force the joint compound to flow into the suction port and into the interior of the spray nozzle.
