Sandpaper is a stiff paper or fabric backing material covered with an abrasive substance such as aluminum oxide, silicon carbide, diamond, garnet, or emery. It removes small amounts of material to buff, debur, polish, and finish wood, metal, fiberglass, drywall, and plastic surfaces. Certain grit grades can be used to remove paint or roughen surfaces for adhesive applications. Sandpaper sheet kits offer you a range of grit sizes or grit numbers, abrasive materials, and grit grades to keep on hand. Rolls are ideal for larger projects or shop environments, allowing workers to tear off the amount of specific sandpaper they need. Sheets are pre-cut.
