How to Sand Wooden Paneling for Painting or Staining (80–320 Grit)

Wood paneling adds warmth and texture to walls, but outdated finishes, scratches, and wear can make it look dull. Sanding is the first step to preparing paneling for paint, stain, or clear coats that will transform a space.

Why Sand Paneling?

Sanding removes old coatings, dulls glossy finishes, and smooths imperfections. It ensures paint or stain adheres properly and gives paneling a refreshed, modern look.

Tools You’ll Need

• Orbital sander for large flat panels
• Sanding sponges for grooves and edges
• Wet/dry sandpaper sheets (80–320 grit)
• Vacuum with brush attachment
• Mask, goggles, gloves

Recommended Grit Sequence

• 80 grit: Removing heavy finishes or rough surfaces.
• 120 grit: General smoothing after coarse sanding.
• 220 grit: Prepping bare wood before paint or stain.
• 320 grit: Final sanding for smooth finishes.

Step-by-Step Process

1. Prep the room. Remove furniture and cover floors to control dust.
2. Start with 80 grit. Use 80 grit (25-pack) to strip thick finishes.
3. Refine with 120 grit. Smooth panels with 120 grit (50-pack) wet/dry sheets.
4. Prep with 220 grit. Sand evenly using 220 grit (100-pack) before primer or stain.
5. Finish with 320 grit. Lightly sand with 320 grit (25-pack) for a polished feel.
6. Clean thoroughly. Vacuum grooves and wipe surfaces with tack cloths.
7. Apply finish. Paint, stain, or seal depending on your design goals.

Special Cases

For veneered paneling, avoid coarse grits below 120 to prevent sanding through the thin surface. For rustic paneling, stopping at 180–220 grit preserves character while still prepping for finish.

Pro Tips

• Sand with the grain for smoother results.
• Use sanding sponges to reach grooves and edges.
• Prime paneling before painting to prevent bleed-through.
• Apply thin coats of finish for long-lasting results.

Aftercare

• Dust paneling regularly to maintain finishes.
• Reapply protective coatings every few years as needed.
• Touch up scratches promptly to avoid deeper damage.

FAQs

• Do I need to sand to bare wood? Yes, for staining. For painting, scuff sanding is usually enough.
• Can I sand paneling by hand? Yes—hand sanding works for grooves and edges.
• What grit is best before painting? 220 grit provides the ideal balance of adhesion and smoothness.
