3M 7100170056 Sanding Sponge Fine Grit 2.625x3.75x1 in

Product Description

The 3M 7100170056 is a fine-grit sanding sponge designed for sanding painted surfaces in residential and light commercial finishing applications. Measuring 2.625 inches by 3.75 inches by 1 inch, its flexible sponge body conforms to flat and mildly contoured surfaces, allowing consistent abrasive contact across the workpiece. The sponge construction resists loading, meaning abraded material clears the surface rather than clogging the grit, which extends usable life and increases coverage per sponge. This part is sold individually and weighs 0.1 pounds.

This sanding sponge is suited for prep and finish work on painted drywall, trim, cabinets, and similar interior surfaces. Painters, drywall finishers, and finish carpenters reach for this style of sponge when blending patches, scuff-sanding between coats, or smoothing factory-painted surfaces before topcoating. The fine grit level makes it appropriate for finish-stage material removal rather than aggressive stock removal.

Installation Notes

This sponge is a hand-use abrasive and does not require power tools or mechanical fastening. When sanding between coats of paint or primer, allow the previous coat to fully cure per the coating manufacturer's guidelines before abrading. Keep strokes consistent and avoid excess pressure, which can cut through finish coats unevenly. Dispose of spent sponges in accordance with local waste guidelines for abrasive materials.
