3M Sanding Sponge, Small Area, 3-3/4 in Lg, 2-5/8 in Wd, Coarse/Medium

3M™ sanding sponges are designed for sanding wood, paint, metal, plastic or drywall. This sponge features conventional 3M™ abrasives and is made with durable, flexible foam. The block shape makes it easy to hold and sands flat, contoured or irregular surfaces. 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.
