The first step in any application is to apply a spit-coat to seal the surface. This is normally done with 220-320 grit sand paper. If you are simply sealing the surface for staining, this is the last step. Remember, many thin layers of finish always work better than one thick layer. After the finish is dry, sand it with at least a 320 grit sandpaper.
Higher grits produce a more finished, reflective surface.
When sanding shellac finishes with such fine sandpaper, it is often necessary to lubricate the sandpaper with mineral oil. This keeps the sandpaper from clogging and becoming useless after just a few passes.
