3M CONTOUR SURFACE SANDING SPONGE - MEDIUM3M's contour sanding sponge conforms to curved profiles - molding, trim, corner blocks, and shaped furniture - where rigid sandpaper would skip over the low spots. The flexible foam backing distributes pressure evenly and lets the abrasive surface follow detailed shapes for smooth, uniform results.
- Grit: Medium
- Pad size: 4-1/2" x 5-1/2"
- Use wet or dry
- Rinse to clear loaded grit and reuse

Tip: Medium is the workhorse grit for prep sanding - removing old paint, smoothing rough wood, and shaping trim profiles before stepping up to Fine or Extra Fine.
Where to use: Initial prep sanding on bare wood, smoothing patched drywall mud, and removing old paint flakes from molding and trim.
