3M™ sanding screens are ideal for removing raised wood grain in the final sanding stage and for abrading between finish coats. Open-mesh construction keeps loading to a minimum and resists the friction and heat of continuous sanding. Plus, the silicon carbide mineral cuts fast and efficiently. The result: less time sanding, less time changing screens. 3M™ Coated Sanding Screen Disc, 7-7/8 in Diameter Disc, 100 Grit, Medium Grade, Silicon Carbide Abrasive, Open Mesh Fabric Backing
