Sanding Painted Wood Surfaces: 80–220 Grit Sandpaper Sheets

When refinishing painted furniture, trim, or doors, proper sanding is key to achieving a smooth, durable new finish. Using 9x11 inch sandpaper sheets in the right grit sequence allows you to strip old paint, smooth the surface, and prepare wood for primer or stain. eQualle’s wet dry silicon carbide sandpaper sheets are built for both aggressive cutting and fine finishing.

Why Sand Painted Wood?

Old paint layers can peel, crack, or bubble. Sanding removes weak paint, levels imperfections, and ensures the next finish adheres properly. Without sanding, new coatings may fail prematurely.

Tools You’ll Need

• eQualle coarse sandpaper sheets
• Sanding block or orbital sander
• Vacuum or tack cloth
• Primer or new paint
• Protective mask and gloves

Best Grits for Painted Wood

• 80 grit — Removes thick or peeling paint. 80 Grit (50-pack).
• 120 grit — Levels wood after paint removal. 120 Grit (25-pack).
• 180 grit — Smooths the surface for primer or stain. 180 Grit (25-pack).
• 220 grit — Final prep before applying new paint. 220 Grit (100-pack).

Step-by-Step Painted Wood Sanding

1. Start with 80 grit sandpaper sheets. Strip peeling or thick layers of old paint, focusing on flat surfaces.
2. Switch to 120 grit. Smooth down rough wood exposed during stripping.
3. Continue with 180 grit sandpaper sheets. Even out the surface and prepare for primer.
4. Finish with 220 grit. Lightly sand before painting for excellent adhesion.

Special Cases

For lead-based paint, use proper protective equipment and follow local safety guidelines. For delicate trim, avoid coarse grits like 80 and begin at 120 grit instead.
