A bull float for leveling and finishing concrete made from two different materials is disclosed. In one embodiment, the main wooden base has an insert made from fiberglass. As the bull float is pushed forward, the pole is angled such that the wooden back edge levels and smooths the concrete, then on the return stroke the pole is raised such that the fiberglass front edge finishes the concrete as the bull float is swept back to the concrete worker. This bull float performs the tasks currently requiring three separate bull floats, thereby saving the worker from having to replace and clean two or three separate bull floats. As concrete sets up quickly, the time savings obtained through using just a single bull float results in superior concrete slabs with less effort required of the concrete worker and more time to work the concrete.

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.

Pole attachment for a skimming tool and a skimming tool system comprising the same A pole attachment for a skimming tool, comprising a clamp, which comprises a pair of jaws (102) for gripping the skimming tool and a clamping mechanism for applying a clamping force to the jaws (102), wherein the clamping mechanism comprises a pair of wings (106), which extend out beyond opposed transverse edges of the jaws (102) in a width direction of the jaws (102).

A trowel (10) is equipped with an optical detector (13) that detects a laser beam (12). The optical detector (13) may be arranged detect the laser beam (12) only when aligned with the laser beam (12). The trowel (10) provides feedback to the user when it detects the laser beam (12) and when it does not. The feedback may be a sound, a light or a haptic feedback. When the trowel (10) is used for constructing a tapered floor, such as in a bathroom, the laser beam (12) may be originated from a laser level (40) arranged on a support (30). The support (30) is positioned inside a floor drain (32), for example a bathroom floor drain (32).

The trowel protector accessory is configured for use with a trowel. The trowel protector accessory is a guard that attaches to the trowel. The trowel protector accessory encloses a plurality of lateral faces of the trowel. The trowel protector accessory prevents the edges of the trowel from causing inadvertent damage. The trowel is stored within the trowel protector accessory. The trowel is removed from the trowel when the trowel is in use. The trowel protector accessory comprises the trowel and the edge guard. The edge guard encloses the plurality of lateral faces of the trowel when the trowel is stored.

A concrete finishing assembly includes a plurality of rails that each has a guide surface. A plurality of couplers each releasably engages a respective pair of the rails for attaching the respective pair of rails together. In this way the plurality of rails defines a border to surround a shower floor. A cylinder is provided and the cylinder can be inserted into a drain in the shower floor. A trowel unit is provided that has an adjustable length and the trowel unit is attachable to the cylinder. The trowel unit is slidable along the guide surface of the plurality of rails that defines the border. In this way the trowel unit can smooth concrete on the shower floor at a predetermined slope for draining water into the drain.

A hand tool. The hand tool includes the hand tool includes a shank, a handle attached to the shank, and a finishing element attached to the shank. The finishing element is attached to the shank by one or more fasteners. The fasteners extend substantially through a hole in the finishing element and an aligned hole in the shank to affix the finishing element to the shank. The fastener has a first expanded end situated in a countersink in an exposed surface of the shank.

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.

A vibration float tool comprising a float pad, an enclosed vibrating component affixed to the top of the float pad, a switch affixed to a battery used for activating and deactivating the enclosed vibrating component, a handle affixed to a surface of the enclosed vibrating component and the battery is used for powering the enclosed vibrating component wherein the battery attached to the handle. A method of using the vibrating float tool to level and settle a semi-liquid construction substrate, comprising activating the enclosed vibrating component with the switch, applying the float pad of the vibrating float tool across the semi-liquid construction substrate, leveling the surface of the semi-liquid construction substrate and setting the semi-liquid construction substrate.
