Sanding is an integral step in preparing a surface to receive a coating. For the best sanding results, sand with the grain of the surface and work through a sequence of grits, from coarse to very fine, skipping no more than one grit between each sanding step. 3M sanding sponges are available in medium, fine and extra fine grits. Sponge material allows abrasive mineral to form into corner, eliminating gouging. Durable, abrasive mineral coating lasts longer than regular sandpaper.
