What purpose do hand floats serve in concrete finishing?

Hand floats are essential tools in the finishing process of concrete, primarily used to start the floating process and produce a level finish. When concrete is placed and leveled, it often requires additional work to achieve the desired smoothness and flatness. The hand float is utilized to work the surface of the concrete after it has been struck off, helping to fill any voids and create a flat surface. This tool can effectively minimize imperfections and ensure that the slab has a uniform surface texture.

The correct use of a hand float contributes greatly to the overall quality of the finished concrete. By applying the float in a systematic manner, the finisher can push down any high spots while simultaneously bringing finer particles to the surface, aiding in the creation of a dense, smooth finish. This is critical in applications such as sidewalks, driveways, and floors where a level surface is necessary for aesthetic and functional purposes.
