Concrete Floor Grinders are vacuum cleaner-sized tools that use horizontally rotating discs to level, smooth or clean a concrete surface. They remove between 1/16″ and 1/8″ of surface material. Concrete floor grinders are analogous to fine sandpaper in a range of masonry tools that includes planers, scabblers, scalers and blasters. Floor grinders can produce the smoothest-looking surfaces. Floor grinders are equipped with a rubber sleeve to ensure that the concrete dust produced by the grinding apparatus remains contained. These floor grinders are gas- or propane-powered and do not require a wall outlet. They are powered by motors that range from 2HP to about 15HP. These floor grinders are used in residential settings.
