Abstract: A film coating or laminate on a surface of a concrete finishing tool, including a film covering a surface, or including a film spanning a space between two surfaces, including for example a film for covering a channel on such tools, and methods relating thereto.

Abstract: A concrete float, float assembly, float adapter and interface, and vibration apparatus and methods are described. A vibration assembly has at least first and second interface components, and for example one interface component can join with an interface component on a pivot assembly and another interface component can join with an interface component on a finishing tool. An interface such as may be included in a quick attach/release configuration may be integrated on vibration apparatus and/or on a pivot assembly for quick attach/release of a joining component. A vibration assembly may include a load transmission or transfer component for transferring a load through the vibration assembly. A pivot assembly may include first and second interface components.

Abstract: A concrete float, float assembly, float adapter and interface, and float vibration apparatus and methods are described. A concrete float has improved surfaces, and structures for controlling flow of wet concrete. An interface such as may be included in a quick attach/release configuration may be integrated on a float, and/or may be added onto a float for quick attach/release of a pivot assembly. Adapters may ease attachment or release of an assembly, and may be an interengaging element, such as a sliding dovetail as an interengaging element, or an adapter may be used to place an assembly in tension to secure the assembly. A vibration assembly may be included and configured to have a low center of mass, can have a user display, an accelerometer, and/or other components. A pivot assembly may be included for easier use by an operator, and may include a user display, quick release mechanisms.
