Sanding Wood Floors Between Coats with 320 Grit Sandpaper Sheets

When refinishing wood floors, sanding between coats is essential for a smooth and professional finish. eQualle 320 grit sandpaper sheets (9x11 in, Wet or Dry) are ideal for this step, helping remove dust nibs and imperfections while preparing the surface for the next coat.

Why 320 Grit for Floors?

320 grit is a very fine abrasive that smooths surfaces without cutting too deeply into the finish. It provides the right level of abrasion for polyurethane and varnish coats, ensuring excellent adhesion and a silky-smooth final look.

Tools You’ll Need

• eQualle 320 Grit Sandpaper sheets (9x11 in, Wet or Dry)
• Floor buffer or sanding block
• Vacuum with brush attachment
• Tack cloth or microfiber rag
• Protective gloves and mask

Step-by-Step: Sanding Between Floor Coats

1. Let the coat cure. Allow polyurethane or varnish to dry completely before sanding.
2. Sand with 320 grit. Use 320 grit (50-pack) sheets to smooth the finish with light, even pressure.
3. Check smoothness. The surface should look evenly dull and feel silky to the touch.
4. Clean thoroughly. Vacuum and wipe with a tack cloth to remove all dust.
5. Apply next coat. Reapply polyurethane or varnish for a flawless finish.

Special Cases

For high-gloss finishes, follow 320 grit with 400 grit before the final coat. For older floors with uneven texture, start with 220 grit, then refine with 320.

Pro Tips

• Always sand with the grain of the wood.
• Use light pressure—320 grit is for smoothing, not stripping.
• Replace sheets often for consistent results.
• Do not sand the final coat—leave it untouched for best shine.

Aftercare

• Let the final coat cure at least 7 days before moving furniture back.
• Use rugs and felt pads to protect your refinished floor.
• Keep extra sandpaper sheets flat and dry for future touch-ups.

FAQs
