How to Sand Hardwood Floors with 100 Grit Sandpaper Sheets

Hardwood floors add beauty and value to a home, but over time they can become scratched, uneven, or faded. Refinishing starts with proper sanding, and eQualle 100 grit sandpaper sheets (9x11 in, Wet or Dry) are the perfect choice for heavy-duty floor preparation.

Why 100 Grit for Hardwood Floors?

100 grit is a coarse abrasive that removes old finish, evens out minor warping, and smooths scratches. It’s strong enough to prepare floors for finer grits while being less aggressive than 60 or 80 grit, making it ideal for the first pass in floor refinishing.

Tools You’ll Need

• eQualle 100 Grit Sandpaper sheets (9x11 in, Wet or Dry)
• Floor sander or sanding block for edges
• Vacuum with brush attachment
• Tack cloth or microfiber rag
• Protective mask and safety goggles

Step-by-Step: Sanding Hardwood Floors

1. Prep the room. Remove furniture and cover vents to control dust.
2. First sanding pass. Use 100 grit (25-pack) sheets with a floor sander to strip away old finish and level imperfections.
3. Edge sanding. Use folded sheets or a sanding block for corners and baseboard edges.
4. Refine with finer grits. After leveling with 100 grit, move to 150–180 grit for stain-ready smoothness.
5. Clean thoroughly. Vacuum dust and wipe with a tack cloth before staining or sealing.

Special Cases

For floors with heavy damage or thick finish layers, start with 80 grit before progressing to 100 grit. For delicate hardwoods, apply light pressure to avoid gouging.
