The Hybrid™ method is a combination of both light grinding and the Twister™ maintenance method that will refurbish a worn stone floor with major scratches or "orange peel". Start with the Hybrid™ black disc and immediately follow up with the Hybrid™ red disc for light grinding of the stone surface. Finish by using the standard Twister™ process to bring up the shine. DCS Hybrid™ Red removes scratches, wear and staining on natural stone and terrazzo floors. DCS Hybrid™ Black is the most aggressive of the Hybrid™ series. It will remove minor scoring, lippage, excessive wear and staining.
