Complete surface finishing jobs on drywall and plaster with the WallSand A221 medium grit paper cut sheet. Use these cut sheets with a sanding block to remove light to moderate material buildup prior to painting walls and ceilings, or use them for hand-sanding tasks. The aluminum oxide grain gently sands surfaces to achieve an even finish. With its flexible and lightweight backing, the sheet conforms to irregular surfaces, and the economical, re-sealable bulk pack reduces the need for frequent reorders.
