How to Sand Wooden Beadboard and Paneling for Painting (120–320 Grit)

Wooden beadboard and paneling add texture and character to walls, but refinishing them requires careful sanding. Whether repainting, staining, or sealing, sanding ensures coatings adhere evenly and highlights the natural grain or grooves.

Why Sand Beadboard?

Over time, beadboard accumulates dust, grease, and old finishes. Sanding removes imperfections, dulls glossy coatings, and smooths surfaces for a clean, even look once repainted or stained.

Tools You’ll Need

• Detail sander or sanding sponge for grooves
• Orbital sander for large flat sections
• Vacuum with brush attachment
• Wet/dry sandpaper sheets (120–320 grit)
• Mask and safety goggles

Recommended Grit Sequence

• 120 grit: Removing old paint gloss and rough spots.
• 180 grit: General smoothing after initial sanding.
• 220 grit: Prepping bare wood for primer or stain.
• 320 grit: Final sanding for silky smooth finishes.

Step-by-Step Process

1. Clean the surface. Wash beadboard or paneling to remove grease and dust.
2. Start with 120 grit. Use 120 grit (25-pack) to scuff old coatings and remove imperfections.
3. Refine with 180 grit. Smooth wood using 180 grit (50-pack) wet/dry sheets.
4. Prep with 220 grit. Sand with 220 grit (100-pack) before priming or staining.
5. Finish with 320 grit. Lightly sand grooves and panels with 320 grit (25-pack) for ultra-smooth results.
6. Clean thoroughly. Vacuum dust from grooves and wipe with tack cloths.
7. Apply finish. Prime, paint, or stain for a refreshed look.

Special Cases

For MDF paneling, avoid coarse grits like 120 on edges—start at 180 to prevent chipping. For vintage beadboard, hand sanding preserves delicate grooves better than machines.

Pro Tips

• Always sand with the grain, especially on visible flat sections.
• Use sanding sponges to reach grooves and bead edges effectively.
• Check under angled light to spot glossy areas that need more sanding.
• Seal grooves carefully to prevent moisture penetration.

Aftercare

• Repaint or restain paneling every 5–7 years for best appearance.
• Dust grooves regularly to prevent buildup.
• Wipe paneling with a damp cloth—avoid harsh cleaners.

FAQs

• Do I need to sand all the way to bare wood? Not always—scuff sanding is enough for repainting.
• Can I sand beadboard by hand? Yes—hand sanding works well for narrow grooves and profiles.
• What grit is best before painting? 220 grit ensures proper adhesion and smoothness.
