Scarifiers are versatile, surface preparation tools used for concrete, asphalt and even steel surfaces. Scarifiers use steel or carbide tipped cutters (in various shapes, depending on application) that are loaded on shafts placed around the perimeter of a cylindrical drum. As the drum rotates, the cutters impact the surface at a high speed, fracturing the coating and/or contaminants and abrading the concrete surface.

These tools are used to remove:

• contaminants
• coatings
• adhesives and
• paint

They are also very useful for preparing problem areas on concrete slabs: burned areas, high spots, curled joints, excessive trowel marks, trip hazards, etc. Many models can be connected to dust collection systems.
