How to Sand Wooden Floors Between Coats with 220 Grit Sandpaper Sheets

When refinishing wooden floors, sanding between coats is crucial for a professional, long-lasting finish. eQualle 220 grit sandpaper sheets (9x11 in, Wet or Dry) are the perfect choice for smoothing polyurethane or varnish layers without damaging the wood underneath.

Why 220 Grit for Floors?

220 grit is a fine abrasive that removes small bubbles, dust nibs, and brush marks between coats. It ensures the next coat bonds well while leaving a silky-smooth surface. This grit is gentle enough to avoid cutting through to bare wood but strong enough to refine the finish.

Tools You’ll Need

• eQualle 220 Grit Sandpaper sheets (9x11 in, Wet or Dry)
• Floor buffer or sanding block
• Vacuum with brush attachment
• Tack cloth or microfiber rag
• Protective mask and eye protection

Step-by-Step: Sanding Between Floor Coats

1. Let the coat cure. Allow polyurethane or varnish to dry at least 24 hours.
2. Sand with 220 grit. Use 220 grit (25-pack) sheets in even strokes or with a floor buffer for large areas.
3. Check smoothness. The floor should feel silky and look evenly dull after sanding.
4. Clean thoroughly. Vacuum dust and wipe with a tack cloth to remove all residue.
5. Apply next coat. Recoat immediately for strong adhesion and a flawless finish.

Special Cases

For high-gloss finishes, follow 220 grit with 320 grit before the final coat. For heavily used floors, lightly screen with 180 grit before the first recoat, then refine with 220 between layers.

Pro Tips

• Always sand with the grain of the wood.
• Use light pressure—220 grit is designed for smoothing, not heavy removal.
• Replace clogged sheets quickly for consistent results.
• Never skip sanding between coats if you want a durable finish.

Aftercare

• Let the final coat cure for 7 days before placing furniture.
• Use felt pads under chairs and tables to protect the finish.
• Store sandpaper sheets flat and dry for future projects.

FAQs

• Can I use 180 grit instead of 220? 180 is slightly coarser and may cut too deep for between coats.
• Do I need to sand the final coat? No—leave the last coat unsanded for a glossy finish.
• Is wet sanding recommended? For wooden floors, dry sanding with dust control is best.
