A concrete float is a tool used to finish a concrete surface by making it smooth. A float is used after the surface has been made level using a screed. In addition to removing surface imperfections, floating will compact the concrete as preparation for further steps.
A float can be a small hand tool, a larger bull float with a long handle, or a power trowel (also called a power float) with an engine.
