3M Company FSB320-PGP-1T 320 Grit Sanding Sponge

Product Description

The 3M COMPANY FSB320-PGP-1T is a 320 grit extra fine sanding sponge designed for finish sanding, light material removal, and surface prep work across a wide range of trade and professional applications. Measuring 2.5 inches x 4.5 inches x 1 inch, the sponge body conforms to contoured and flat surfaces, allowing consistent abrasive contact without the need for a backing block. At 320 grit, it is suited for final smoothing passes before priming or coating. Tradespeople handling drywall finishing, light woodwork, and surface prep on fixtures or trim reach for this grit range when a smooth, paint-ready surface is the goal.

This sanding sponge fits into finish carpentry, drywall, plumbing trim-out, and general construction prep workflows. It is well suited for smoothing joint compound, scuffing primed surfaces, and deburring light materials. The flexible foam body makes it practical for working around pipes, molding edges, and other irregular profiles where flat sandpaper loses contact. It is sold individually and packaged in quantities of 12 units per package, making it a practical shelf or truck-stock item for contractors who go through abrasives regularly.

Installation Notes

No power tools or special equipment are required for use. Apply even hand pressure and work in the direction of the grain or surface texture to avoid cross-grain scratches. When sanding joint compound or drywall, wear an appropriate dust respirator in accordance with local safety requirements. Replace the sponge when abrasive loading reduces cutting performance.
