Refinishing Wooden Doors: 80–240 Grit Sandpaper Sheets

Wooden doors face constant use and exposure, which can leave them scratched, dented, or covered in worn finishes. Refinishing with 9x11 inch sandpaper sheets restores their smoothness and prepares them for paint or stain. eQualle’s wet dry silicon carbide sandpaper sheets are perfect for every stage of door restoration.

Why Sand Wooden Doors?

Sanding removes old finishes, evens out imperfections, and creates the right texture for coatings to bond. Without sanding, paint or stain may peel or look uneven, especially on high-touch surfaces like doors.

Tools You’ll Need

• eQualle wood sanding sandpaper sheets
• Sanding block or orbital sander
• Vacuum and tack cloth
• Paint or wood stain with finish
• Protective gloves and mask

Best Grit Sequence for Door Refinishing

• 80 grit — Removes old paint, stain, or varnish. 80 Grit (50-pack).
• 120 grit — Smooths after stripping finish. 120 Grit (25-pack).

Step-by-Step Door Sanding

1. Begin with 80 grit sandpaper sheets. Strip away old paint, stain, or varnish using consistent strokes with the grain.
2. Switch to 120 grit. Smooth rough surfaces and erase marks left by coarse sanding.
3. Continue with 180 grit sandpaper sheets. Refine scratches and prepare the door for primer or stain.
4. Finish with 240 grit. Lightly sand before applying paint or clear finish for a flawless surface.

Special Cases

For paneled doors, fold sheets to reach grooves and edges. For exterior doors, consider sanding down to bare wood and resealing to protect against weathering.
