3M Sanding Sponge CP001, Fine Grit, Full Size, Reusable Wet or Dry Sanding Block

The 3M Sanding Sponge CP001 is a full size sanding sponge built for dry or wet sanding of wood, paint, metal, plastic, and drywall. The fine grade abrasive surface is conformable, comfortable, and flexible in the hand, so it follows flat, contoured, and irregular surfaces without gouging or leaving flat spots the way a rigid sanding block can. It is designed to be rinsed clean and reused rather than discarded after a single job, making it a practical choice for painters, woodworkers, and DIYers who need consistent fine-grit results across multiple projects.

Because the abrasive is bonded to a conformable sponge body rather than a flat pad, the CP001 keeps even pressure on corners, edges, and molding profiles that a flat sanding sheet would miss. It measures 3.75 inches long by 2.63 inches wide by 1 inch thick, sized to be held comfortably in one hand for detail and touch-up sanding work. The fine grit is suited to light surface smoothing and finish prep rather than heavy material removal, and it can be used wet to reduce dust or dry for faster cutting depending on the job.
