How to Sand a Wooden Desk for Refinishing: Smooth, Durable Results (60–320 Grit Guide)

Refinishing a wooden desk can restore its beauty and extend its lifespan. Proper sanding removes old finishes, smooths imperfections, and creates a surface that’s ready for stain, paint, or clear coat.

Why Sand a Desk Before Refinishing?

Desks often accumulate scratches, water rings, dents, and worn finishes from years of use. Sanding levels the surface, opens the grain for better finish penetration, and ensures a professional-quality result.

Tools & Materials

• Orbital sander and sanding block
• Vacuum and tack cloth
• Drop cloths to protect floors
• Wet/dry sandpaper sheets
• Safety gear: dust mask, safety glasses, gloves

Recommended Grit Sequence

• 60 grit: Removing heavy finish and leveling rough areas.
• 120 grit: Smoothing after coarse sanding.
• 220 grit: Pre-finishing preparation.
• 320 grit: Final surface refinement before applying finish.

Step-by-Step: Sanding a Wooden Desk

1. Prepare the workspace. Move the desk to a well-ventilated area and cover surrounding surfaces.
2. Coarse sanding. Use 60 grit (25-pack) to remove old finish and smooth deep imperfections.
3. Intermediate sanding. Switch to 120 grit (50-pack) to refine the surface and remove coarse sanding marks.
4. Pre-finishing. Use 220 grit (100-pack) for a smooth, even texture ready for stain or paint.
5. Final sanding. Lightly sand with 320 grit (25-pack) to create a flawless, finish-ready surface.
6. Clean thoroughly. Vacuum and wipe with a tack cloth to remove all dust.
7. Apply finish. Stain, paint, or clear coat according to manufacturer instructions, sanding lightly between coats if necessary.

Special Cases

For veneered desks, start with 120 grit to avoid sanding through the thin surface layer.

Pro Tips

• Sand with the grain to avoid visible scratches.
• Use sanding sponges for curved or detailed areas.
• Inspect the surface under good lighting before applying finish.

Aftercare

• Allow finishes to cure fully before placing items on the desk.
• Use coasters and desk pads to protect the surface from future damage.

FAQs

• Do I have to remove all old finish? Yes, for the most even and durable result.
• Can I hand sand the entire desk? Yes, but it will take longer—use a power sander for flat surfaces to save time.
