A grout float is a hand tool used to apply grout to tile, whether on a wall or floor (there are specific types for each application). It typically has some sort of handle on it to make it easy to hold, and a rubber pad where the grout is positioned. The putty-like mixture is worked between tiles at an angle to provide a clean and even finish to the tiling job.
