Power PRO 2100-120 Grit -10Pcs 9inch/225mm Sanding Abrasive Discs, Sandpaper for Drywall Sander and Polisher, 1 Set with 10 Vent Holes (120 Grit);

This 10-pack of Power Pro #120 Grit Hook and Loop Drywall Sanding Discs attaches to the Power Pro Series drywall sanders for material removal and resurfacing. The hook and loop (Velcro) system allows for quicker, easier disc changing and the #120 grit discs will be most useful for the early-mid stages of drywall compound application. For smoothing surfaces and removing larger imperfections, use 80- to 120-grit sandpaper. For finishing surfaces smoothly, use a fine sandpaper with 150- to 240-grit. Many jobs require you to "go through the grits." This means you start the project using lower-grade grit and use finer pieces of sandpaper as you progress. Each time you advance to a higher grit sandpaper, you remove the scratches from the previous layer.
