Sanding Wooden Office Desks with 9x11 Sandpaper Sheets (80, 120, 180, 220 Grit Guide)

Office desks are workhorses, often showing scratches from laptops, dents from pens, and worn finishes from constant use. Sanding with 9 x 11 inch sandpaper sheets is the best way to restore them before applying stain, paint, or varnish. Following the proper grit sequence ensures a smooth, durable, and professional surface.

Why Sand Office Desks?

Daily use leaves desks dull, scratched, and uneven. Sanding removes imperfections, smooths the surface, and prepares the wood grain for coatings that will protect it for years. Without sanding, finishes may not adhere properly and flaws will remain visible.

Tools You’ll Need

• Orbital sander for large flat areas
• Sanding block for edges
• Sanding sponge for corners and trim
• Vacuum and tack cloth
• Protective goggles and mask
• Assorted 9 x 11 inch sandpaper sheets

Best Grit Sequence for Office Desks

• 80 grit (50-pack, 9x11 in) — Removes old coatings and deep scratches.
• 120 grit (25-pack, 9x11 in) — Smooths rough sanding marks.
• 180 grit (50-pack, 9x11 in) — Refines the surface before finishing.
• 220 grit (100-pack, 9x11 in) — Final sanding pass for a silky, finish-ready surface.

Step-by-Step: Sanding Office Desks

3. Smooth with 120 grit. Switch to 120 grit sheets for even texture.
4. Refine with 180 grit. Apply 180 grit sheets to prepare for coatings.
5. Finish with 220 grit. Use 220 grit 9x11 inch sheets for a flawless, finish-ready surface.
6. Clean thoroughly. Vacuum and wipe with tack cloth before staining or painting.
