3M All Purpose Sanding Sponge SSM, Medium Grit, 3-3/4 x 2-5/8 x 1 Inch

The 3M All Purpose Sanding Sponge (SSM) is a medium-grit foam sanding block sized 3-3/4 inches by 2-5/8 inches by 1 inch, built for sanding wood, paint, metal, plastic, and drywall. The medium grit is suited to moderate stripping or surface leveling ahead of a top coat, making it a practical choice for prep work before painting or refinishing marine surfaces, trim, or fittings. The sponge is made from a flexible foam body that carries conventional 3M abrasive material, so it can be used wet or dry depending on the job and the mess tolerance of the work area.

Its block shape is designed to sit comfortably in the hand, and the flexible foam construction lets it conform to flat, contoured, or irregular surfaces alike, so it can follow curves and edges that a rigid sanding block cannot reach. For best results, sand with the grain of the surface, and work through a sequence of grits from coarse to fine, skipping no more than one grit between each step. The sponge can be rinsed clean and reused across multiple sanding sessions, extending its usable life compared to disposable sandpaper sheets.
