3M CONTOUR SURFACE SANDING SPONGE - EXTRA FINE3M'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: Extra Fine
- Pad size: 4-1/2" x 5-1/2"
- Use wet or dry
- Rinse to clear loaded grit and reuse
- Works on drywall, paint, metal, plastic, and wood
- Flexible foam pad conforms to shaped surfaces
Tip: Extra Fine is the final sanding step before a finish coat - use after a Medium or Fine pass to remove deeper scratches and prep the surface for stain, paint, or clear coat.
Where to use: Final prep on stained or clear-coated trim, scuffing between topcoats on furniture, and smoothing dust nibs in cured varnish or polyurethane.
