Introducing Festool's all new Granat abrasive, one that we have come to refer to as the ultimate abrasive, due in no small part to its amazing versatility. Though originally designed for use on solvent-based, high-VOC surfaces (volatile organic compounds) and hard surface paints, its anti-clogging properties are well suited for a much broader range of applications. Use Granat not only for sanding and finishing clear coats, plastics, mineral-based surfaces, solid surface materials and acrylics, but also for wood, composites or just about any other surface type.
