Refinishing Wooden Desks for a Smooth Work Surface (80, 120, 180, 220 Grit Guide)

A desk sees constant use—writing, typing, spills, and scratches all leave their mark over time. Sanding is the first step in restoring an old desk or preparing a new one for finishing. By following the right grit sequence, you can create a flawless surface that’s durable and attractive for years to come.

Why Sand Desks?

Scratches, dents, and worn finishes make desks look tired and uneven. Sanding removes old coatings, smooths imperfections, and preps the wood grain to absorb stain, paint, or clear coat evenly. Without sanding, finishes may peel or look blotchy.

Tools You’ll Need

• Orbital sander for large flat surfaces
• Sanding sponge or block for edges
• Vacuum and tack cloth
• Protective mask and glasses
• Assorted wood sanding sheets

Best Grit Sequence for Desk Refinishing

• 80 grit (50-pack) — Removes old finish and deep scratches.
• 120 grit (25-pack) — Smooths rough sanding marks.
• 180 grit (50-pack) — Refines the surface before fine sanding.
• 220 grit (100-pack) — Prepares the desk for stain, paint, or varnish.

Step-by-Step: Sanding a Wooden Desk

1. Prep the workspace. Remove drawers, hardware, and clean the desk surface.
2. Strip with 80 grit. Use 80 grit sandpaper to remove old coatings and level imperfections.
3. Smooth with 120 grit. Switch to 120 grit sheets to refine the surface.
4. Refine with 180 grit. Apply 180 grit sheets for an even, consistent finish.
5. Finish with 220 grit. Use 220 grit sheets for a silky, finish-ready surface.
6. Clean thoroughly. Vacuum and wipe before applying finish.

Special Cases

• Veneer desks: Be careful—too much sanding can wear through the thin veneer.
• Antique desks: Sand lightly to preserve character and value.
• Painted desks: If paint is in good shape, start with 120 grit instead of 80.

Pro Tips

• Always sand with the grain for the best finish.
• Use sanding sponges to reach corners and edges.
• Work evenly across surfaces to avoid dips.

Aftercare

• Seal with a durable clear coat to protect the surface from daily wear.
• Clean with mild soap—avoid abrasive cleaners.
• Use coasters and desk mats to prevent scratches.

FAQs

• Do I need to sand between finish coats? Yes, a light pass with 220 grit ensures smooth adhesion.
• Can I sand by hand? Yes, but an orbital sander saves time for large surfaces.
• How long does sanding a desk take? Typically 2–3 hours depending on size and condition.
