Sanding Painted Wood Furniture: Smooth Refinish Without Stripping

Repainting old furniture doesn’t always require harsh chemical strippers—light sanding can give you a perfectly smooth surface ready for new paint or primer. Whether you’re restoring a vintage dresser or updating a chair, the right sanding process removes sheen, smooths imperfections, and ensures your new finish lasts.

Why Sanding Painted Wood Matters

Old paint layers can hide bumps, drips, or uneven grain that show through new coats. Sanding evens the surface and removes gloss so that new paint adheres firmly. It’s cleaner and safer than chemical stripping, especially for small or detailed pieces.

Recommended Tools

• 9×11-inch silicon carbide sandpaper sheets.
• Sanding sponge or orbital sander.
• Vacuum and tack cloth for cleanup.
• Degreaser or mild soap for surface cleaning.
• Primer and furniture paint.

Grit Sequence

• 150 grit: Scuffing glossy paint and leveling rough areas.
• 220 grit: Smoothing before primer or paint.
• 320 grit: Optional final sanding for ultra-smooth topcoats.

Step-by-Step: Sanding Painted Furniture

1. Clean the surface. Wipe furniture with a degreaser or soapy water to remove oils, dust, and residues. Let dry completely before sanding.
2. First sanding pass. Use 150 Grit (25-pack) to remove surface gloss and level imperfections. Sand lightly—there’s no need to strip all the old paint unless it’s flaking.
3. Refine the surface. Move to 220 Grit (50-pack) to smooth out scratch marks and prepare for primer. Always sand with the grain on wooden surfaces.
4. Final smoothing (optional). For high-gloss finishes, finish with 320 Grit (100-pack) for an ultra-smooth base. This ensures your new paint flows evenly.
5. Clean thoroughly. Vacuum dust and wipe with a tack cloth before painting or priming.
6. Prime and paint. Apply a bonding primer, followed by thin coats of furniture paint. Lightly sand between coats with 320 grit for a flawless finish.

Special Cases

For chipped or heavily layered paint, use 120 grit to feather edges before continuing with finer grits. On curved or detailed furniture, wrap sandpaper around a sponge to maintain consistent contact without removing too much material.

Pro Tips

• Use silicon carbide sandpaper—it cuts cleanly through paint and resists clogging.
• Always wear a dust mask when sanding old finishes—some may contain lead.
• Don’t skip cleaning—grease and dust can cause paint to peel later.
• Apply primer soon after sanding to prevent dust or moisture from settling on the surface.

Aftercare

• Allow painted furniture to cure for at least 7 days before heavy use.
• Clean gently with a soft cloth—avoid harsh cleaners for the first month.
• Recoat or touch up as needed using the same grit sequence for consistency.

FAQs

• Do I need to remove all old paint? No—just sand enough to dull the sheen and smooth the surface.
• Can I skip sanding if I use chalk paint? Light sanding is still recommended for best adhesion and smooth texture.
• Can I sand between paint coats? Yes—use 320 grit to eliminate brush marks and dust nibs between layers.
