Make your sanding projects less work with 3M SandBlaster 220 Grit Sandpaper with No-Slip Grip Backing. Use this 220 grit sandpaper to scuff the top coat to prepare the surface for the next coating layer. The sharp, synthetic minerals of this fine sandpaper cut fast, stay sharp, and resist clogging, which extends the sanding life of each sheet. for optimal results, be sure to sand with the grain of the wood and work through a sanding sequence, from coarse to very fine, skipping no more than one grit between stages. Use the color-coded package of this 3M sandpaper to select the right kind for each stage of sanding, and note that the colored abrasive will NOT discolor the surface you are sanding. Coming in a pack of 3, these sheets of sandpaper can be used by hand, on a sanding block, or cut it to size for a power tool sander.
