Scarifying is one method used to level a floor and to prepare a concrete floor for further treatment.
A concrete scarifier comes equipped with a rotating, cutting tool that rotates at a high speed and tears the surface apart.
Scarification works by using steel and or carbide star shaped cutters mounted in rows with several rows around the perimeter of a rotating drum. The cutters come in several sizes and variations for different applications. With this drum machines can remove between ¼ inch and 2 inches in a single pass. Scarifiers are most often seen in the road construction business. They can be used for the removal of asphalt roads traffic lines, grinding down high spots and grooving the surface. Scarification is very effective in removal of old coating and resurfacers.
