Sanding Wooden Chairs for a Smooth Refinish (80, 120, 180, 220 Grit Guide)

Wooden chairs endure daily use, leaving them with scratches, dents, and worn finishes. Whether you’re restoring an antique or updating kitchen seating, sanding is the first step to achieving a professional finish. With the right grit sequence, chairs can be transformed into stunning pieces that complement any home décor.

Why Sand Chairs?

Chairs have many curves and details that collect dirt and show wear. Sanding removes old coatings, smooths imperfections, and preps the wood for stain or paint. Without sanding, finishes won’t adhere properly and flaws remain visible.

Tools You’ll Need

• Sanding sponges for curves and edges
• Orbital sander for flat sections
• Detail sander or hand sanding for tight spots
• Vacuum and tack cloth
• Assorted wood sanding sheets

Best Grit Sequence for Chair Refinishing

• 80 grit (50-pack) — Removes old paint or varnish and levels deep scratches.
• 120 grit (25-pack) — Smooths coarse sanding marks.
• 180 grit (50-pack) — Refines surfaces and preps for finer sanding.
• 220 grit (100-pack) — Final sanding pass before stain, paint, or clear coat.

Step-by-Step: Sanding Wooden Chairs

1. Prep the chair. Remove cushions or upholstery and clean surfaces.
2. Start with 80 grit. Use 80 grit sandpaper to strip old coatings and smooth rough areas.
3. Smooth with 120 grit. Switch to 120 grit sheets for more even surfaces.
4. Refine with 180 grit. Apply 180 grit sheets on spindles and arms for an even texture.
5. Finish with 220 grit. Use 220 grit sandpaper to achieve a silky, paint-ready surface.
6. Clean thoroughly. Vacuum and wipe with tack cloth before applying finish.

Special Cases

• Antique chairs: Sand lightly to preserve detail and character.
• Softwood chairs: Avoid aggressive sanding to prevent gouges.
• Painted finishes: If the paint is sound, feather with 120–180 grit instead of full stripping.

Pro Tips

• Always sand with the grain for smoother results.
• Use sanding sponges for carved or rounded areas.
• Change sheets often—chairs have many surfaces that quickly dull sandpaper.

Aftercare

• Seal chairs with a durable clear coat or paint for protection.
• Clean gently with a damp cloth—avoid abrasive cleaners.
• Reapply finish every few years for long-term durability.

FAQs

• Can I sand chairs by hand? Yes, but sanding sponges and blocks make it easier.
• Do I need to sand between finish coats? Yes, lightly with 220 grit for adhesion.
• How long does sanding a chair take? Typically 1–2 hours depending on design and condition.
