Refinishing Wood Doors: Sanding for a Flawless Finish (60–320 Grit Guide)

Wood doors take daily abuse—scuffs, scratches, and faded finishes are common. Sanding is the essential first step to bring life back to worn doors, whether you plan to stain or paint. This guide covers grit sequences and best practices for smooth, professional results.

Why Sand Wood Doors?

Sanding removes old finishes, smooths dents, and prepares the wood to accept new coatings. Without sanding, paint or stain may peel, chip, or absorb unevenly.

Best Tools for Door Sanding

• 9x11 in silicon carbide sandpaper sheets
• Orbital sander for flat panels
• Sanding block for edges and details
• Vacuum with brush attachment
• Protective mask and goggles

Recommended Grit Sequence

• 60–80 grit: Strip paint or varnish.
• 120 grit: Smooth surface after stripping.
• 180 grit: Prepare bare wood for finish.
• 220–320 grit: Final smoothing before staining or painting.

Step-by-Step: Sanding a Wooden Door

1. Remove the door. Take it off the hinges and place flat on sawhorses.
2. Start with coarse grit. Strip old finish using 60 Grit (25-pack) or 80 Grit (50-pack).
3. Smooth with 120 grit. Remove coarse scratches and level surfaces. Try 120 Grit (100-pack).
4. Refine with 180 grit. Sand along the grain to prep for finish.
5. Finish with 220–320 grit. Light sanding creates a silky texture for stain or paint.
6. Clean thoroughly. Vacuum and wipe with a tack cloth.
7. Apply finish. Stain or paint, followed by a protective topcoat.

Special Cases

For paneled doors, fold sandpaper to fit grooves. For veneered doors, avoid coarse grits below 120 to prevent sanding through the veneer.

Pro Tips

• Sand evenly across all sections for a uniform look.
• Always sand with the grain.
• Replace sandpaper often—clogged sheets scratch instead of smooth.
• Work outdoors or in a well-ventilated area to control dust.

Aftercare

• Let finishes cure fully before rehanging the door.
• Clean with mild soap and a damp cloth—avoid harsh chemicals.
• Touch up scratches promptly to protect wood from moisture.

FAQs

• Can I sand without removing the door? Yes, but laying it flat makes sanding easier and prevents drips during finishing.
• Do I need to sand between coats of paint? Yes, lightly with 220 grit for smooth results.
• What grit should I stop at for staining? 180–220 grit provides the best absorption balance.
