Sanding Doors Before Painting with 120 Grit Sandpaper Sheets

Doors are high-traffic surfaces that often develop scratches, dents, and uneven finishes. Before painting, proper sanding ensures smooth adhesion and a professional look. eQualle 120 grit sandpaper sheets (9x11 in, Wet or Dry) are excellent for prepping wooden doors.

Why 120 Grit for Doors?

120 grit is a medium-coarse abrasive that removes old paint, smooths imperfections, and opens wood pores for primer and paint adhesion. It’s coarse enough for effective material removal but fine enough to avoid deep scratches.

Tools You’ll Need

• eQualle 120 Grit Sandpaper sheets (9x11 in, Wet or Dry)
• Sanding block or orbital sander
• Detail sander or folded sheets for edges
• Vacuum with brush attachment
• Tack cloth or microfiber rag
• Protective gloves, mask, and goggles

Step-by-Step: Sanding Doors

1. Remove hardware. Take off handles, hinges, and locks for easier sanding.
2. Sand with 120 grit. Use 120 grit (25-pack) sheets to strip paint and smooth the door surface.
3. Detail sanding. Fold sandpaper to reach corners, panels, and grooves.
4. Refine with finer grit. After leveling, follow with 180–220 grit for paint-ready smoothness.
5. Clean surface. Vacuum and wipe with a tack cloth before priming and painting.

Special Cases

For doors with multiple paint layers, start with 80 grit before moving to 120. For veneer doors, sand lightly to avoid sanding through the thin surface layer.
