Scarification is used primarily for the removal of concrete, brittle coatings, and polymer overlays. A scarifier may also be used to profile concrete surfaces for the application of self-leveling systems, broadcast systems, and overlays. In scarifying, rotating cutters mounted to the perimeter of a drum impact the substrate surface at a high rate of speed. The impact of the rotating cutters fractures and pulverizes the substrate, creating a surface profile. The scarifier is guided in parallel slightly overlapping paths creating a striated pattern. Failing to remove damaged concrete, coatings, and floor toppings prior to new resinous flooring installation is a leading cause of industrial flooring failure.
