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.

When spreading adhesive, an adhesive spreader tool and adaptor for attachment to a handle, the adaptor and spreader tool for spreading adhesive over a floor surface from a standing position. The spreader tool includes two sheets each sheet folded along respective at least one slot to form a folded portion of the sheet. Once the two sheets are joined they form an array of castellations along respective first sides of the joined sheets and end walls formed by the folded portions, the sheets suitable for spreading adhesive over the floor the width of a tile. The adaptor is configured to engage the adhesive spreader tool and has first and second longitudinal support members adapted to be slidable within a first channel or one in each of two channels so that the support members support.

A trowel cleaning device cleans mortar that has set on the serrated edge of the trowel. The trowel cleaner uses a rectangular solid block member that has a ridge pattern on at least the first face and can also be included on one or more additional faces of the block up to all six of its faces. Each ridge pattern corresponds to a serration pattern on a trowel in both size and shape so that as the serrated edge of the trowel is pulled through the ridge pattern, the ridge pattern scrapes off any mortar that has set onto the serrated edge.

Electronic trowels, systems and methods of applying a layer of material using the present electronic trowels. The various electronic trowels include a handle, at least one blade, and one or more sensors residing on or within the trowel. The trowel is for applying a layer of material over a surface area, whereby the one or more sensors detect and collect material installation data during application of the layer of material over the surface area. One or more electronic devices coupled to the one or more sensors receive and analyze the collected installation data for monitoring and controlling the application of the layer of material to ensure a desired end product is achieved. Application errors may be detected before, during, or after the installation process.

An adhesive composition for adhesively bonding floor coverings to a variety of substrates. The composition includes 0.2 to 10 weight percent of a plurality of irregularly shaped spacer particles of size 0.5 mm to 10 mm; 10 to 50 weight percent of a moisture curable polymer system; and 40 to 90 weight percent of additives for modifying physical properties of the composition. The adhesive has a composition such that, when cured, results in an elastomeric film of uniform thickness that exhibits controlled moisture vapor transmission and sound abatement properties. A floor structure and a method for constructing the floor structure using the adhesive composition are also provided.

A combination trowel may include a handle, a flat-edge blade coupled to the handle, and a notched-edge blade coupled to the handle and located along a first surface of the flat-edge blade. In some embodiments, the notched-edge blade is slideably coupled to the handle such that the notched-edge blade can extend and retract with respect to the handle. A thumb slide coupled to the handle may be configured to facilitate the extension and retraction. The handle may comprise a first portion and a second portion, and the second portion may be configured to extend and retract with respect to the first portion. A first rivet and a second rivet may be used to couple the handle to the flat-edge blade and the notched-edge blade.

A tool is shaped for working a mud patch in a shower enclosure. The tool has front and rear edges with sections angled relative to each other to allow easily contacting angled edges of the walls of the shower enclosure.
