How to Sand Wood Paneling for a Modern Painted Finish

Wood paneling can look outdated—but with the right prep, you can transform it with a fresh coat of paint. The key is proper sanding. This SEO-optimized guide walks you through how to sand wood paneling step by step, with the best grit choices and pro tips for a smooth, modern finish that lasts.

Why Sand Wood Paneling Before Painting?

Sanding removes surface gloss, smooths imperfections, and helps primer and paint adhere better to wood veneer or solid wood panels. It also ensures a longer-lasting, chip-resistant finish.

Best Sandpaper Grits for Wood Paneling

• 100–120 grit sandpaper: For removing sheen or surface coating.
• 150–180 grit sandpaper: For smoothing after patching or caulking seams.
• 220 grit sandpaper: For final prep before applying primer.

Step-by-Step: How to Sand Wood Paneling

1. Clean the paneling thoroughly to remove dust, oils, or smoke residue.
2. Lightly sand the entire surface with 100–120 grit to scuff the sheen.
3. Fill nail holes or gaps with wood filler and let dry.
4. Use 150–180 grit to smooth filler and seams.
5. Finish with 220 grit to prepare for primer or paint.

Tips for Even Sanding on Paneling

• Use a sanding sponge to reach into grooves and trim edges.
• Always sand with the wood grain to avoid visible scratches.
• Vacuum and wipe paneling with a tack cloth before priming.
