How to Sand Wooden Chairs for a Smooth, Comfortable Finish (80–320 Grit Guide)

Sanding wooden chairs is essential for achieving a professional, comfortable finish. The right grit sequence removes roughness, smooths curves, and prepares the surface for stain, paint, or sealant.

Why Sand Chairs?

Chairs often have scratches, dents, and uneven finishes from frequent use. Sanding refreshes the surface, enhances comfort, and ensures finishes adhere properly.

Tools & Materials

• Orbital sander and sanding block
• Sanding sponges for rounded edges
• Vacuum and tack cloth
• Wet/dry sandpaper sheets
• Dust mask, safety glasses, gloves

Recommended Grit Sequence

• 80 grit: Removing heavy finish or damage.
• 150 grit: Smoothing after coarse sanding.
• 220 grit: Pre-finishing preparation.
• 320 grit: Final smoothing before finish application.

Step-by-Step: Sanding Wooden Chairs

1. Prepare the workspace. Place the chair on a drop cloth in a well-ventilated area.
2. Coarse sanding. Use 80 grit (100-pack) to strip old finish and smooth damaged areas.
3. Intermediate sanding. Smooth the wood with 150 grit (25-pack) to remove coarse marks.
4. Pre-finishing. Use 220 grit (50-pack) for an even, refined texture.
5. Final sanding. Lightly sand with 320 grit (25-pack) for a silky surface ready for finishing.
6. Clean thoroughly. Vacuum and wipe with a tack cloth to remove dust.
7. Apply finish. Stain, paint, or seal according to your preference, sanding lightly between coats if needed.

Special Cases

For spindles and carved details, wrap sandpaper around a dowel or use a fine sanding sponge for precise work.
