What is the primary function of a concrete float?

The primary function of a concrete float is to level and smooth concrete surfaces. This tool is typically used during the finishing stage of concrete work, after the concrete has been poured and roughly leveled. The float helps to create a flat surface by consolidating the top layer of concrete, making it smoother and more even. It also helps to bring the finer aggregate particles toward the surface, which is important for achieving a high-quality finish. Using a float properly ensures that imperfections are minimized and creates a surface that is visually appealing and more durable.
