3M SandBlaster Sandpaper with NO-SLIP GRIP Backing, 20400-G 9 in x 11 in, 400-grit, 3 sheets/pk. Make your sanding projects LESS WORK with 3M SandBlaster high performance abrasives. Use this 400-grit (extra fine) sandpaper to smooth the final top coat and achieve a high-gloss finish. The sharp, synthetic minerals 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 and sandpaper to select the right sandpaper for each stage of sanding. The colored abrasive will NOT discolor the surface you are sanding. Sheets of sandpaper can be used by hand, on a sanding block, or cut it to size for a power tool sander.
