Refinishing Wooden Doors with eQualle Sandpaper Sheets (80, 150, 220, 400 Grits)

Wooden doors often suffer from scratches, fading, and layers of old paint or varnish. Instead of replacing them, you can restore their beauty with proper sanding and finishing. Using eQualle Sandpaper Sheets (9 x 11 inches), you can achieve a smooth, professional surface ready for paint, stain, or clear finish.

Why Sanding Doors Matters

Doors are exposed to constant use, sunlight, and sometimes moisture. Sanding removes damaged coatings and prepares the surface for new finishes that will last longer and look better.

Essential Tools

• eQualle Sandpaper Sheets (9x11 in)
• Orbital sander and sanding block
• Painter’s tape and drop cloths
• Vacuum or tack cloth
• Wood primer, stain, or varnish
• Safety goggles and dust mask

Recommended Grit Sequence

• 80 Grit (25-pack) — For stripping old paint, varnish, or heavy imperfections.
• 150 Grit (50-pack) — For smoothing after coarse sanding and leveling surfaces.
• 220 Grit (25-pack) — For fine sanding before primer, stain, or paint.
• 400 Grit (100-pack) — For polishing between coats of finish for a flawless surface.

Step-by-Step Process

1. Remove hardware. Take off hinges, knobs, and locks for easier sanding.
2. Strip with 80 grit. Sand away old finishes and rough patches using steady strokes.
3. Smooth with 150 grit. Refine the surface and eliminate coarse sanding marks.
4. Fine sand with 220 grit. Prepare the door for primer or stain with an even finish.
5. Apply primer or stain. Let dry fully before proceeding.
6. Polish with 400 grit. Lightly sand between coats of varnish or paint for a silky-smooth finish.
7. Seal and protect. Apply a final coat for durability and long-lasting beauty.

Special Cases

For paneled doors, fold sandpaper sheets to fit grooves and details. Use finer grits to avoid damaging edges and trim.

Pro Tips

• Always sand with the wood grain to avoid scratches.
• Vacuum dust between sanding stages to prevent contamination.
• Use painter’s tape to protect glass panels or adjacent walls.
• Consider wet sanding with 400 grit for a polished final coat.

Aftercare

• Dust doors regularly to maintain finish.
• Avoid abrasive cleaners that dull the coating.
• Reapply protective finish every few years for longevity.

FAQs

• Do I need to sand if repainting a door? Yes, sanding ensures paint adhesion and prevents peeling.
• What grit is best before staining? 220 grit is ideal for stain absorption and smoothness.
• Can I sand by hand? Yes, but an orbital sander speeds up large flat surfaces.
