Concrete Scarifiers, also known as surface planers or milling machines, cut or scar the surface of concrete with the use of cutting tools. These machines are great for preparing concrete or metal surfaces for secondary processes like coating, painting, and leveling. Concrete Scarifiers can also groove walkways to improve slip resistance. You can achieve different finishes by adjusting the spacing and pattern of the cutter assemblies.
Scarifiers remove concrete faster and more aggressively than grinders due to the pummeling action of the cutting wheels that rotate at very high speeds. The cutters chip away at the concrete leaving rough surface profiles for various purposes. Cutting depths are adjustable on most surfacing machines.
