Sand hardwood floor (hickory) to screen sand between coats without...

Quick plan: clean → 80 grit to level → step up through 220 grit → final wipe → screen sand between coats without swirl marks.

This guide is a simple checklist for sanding a hardwood floor (hickory) with an even scratch pattern.

Why Sanding Matters

Sanding removes defects and sets the surface profile that the next layer needs. If the scratches are inconsistent, they can show through paint, clear coat, or polish—especially under angled light. A steady grit progression makes the finish predictable.

Recommended Tools

• Sandpaper sheets (cut to size)
• Sanding block / pad
• Clean cloths + vacuum/brush
• Masking tape
• Dust mask / respirator + gloves

Recommended Grit Sequence

Work in order. Don’t move up until the previous scratch pattern is fully removed.

• 80 grit — remove the previous scratch pattern fully.
• 120 grit — remove the previous scratch pattern fully.
• 150 grit — remove the previous scratch pattern fully.
• 180 grit — remove the previous scratch pattern fully.
• 220 grit — remove the previous scratch pattern fully.

Step-by-Step

1. Prep the area. Tape off adjacent surfaces and protect edges/trim that shouldn’t be sanded.
2. Clean thoroughly. Remove oils and dust so the paper cuts evenly.
3. Start with 80 grit. Use even strokes. Keep the block flat on flats; on curves, use a flexible pad.
4. Use a direction change. Slightly change stroke direction when you switch grits so you can see when older scratches disappear.
5. Step up through 120 and 150 grit. Reduce pressure as you go finer.
6. Refine with 180 grit. Focus on consistency—no heavy pressure, no stopping in one spot.
7. Finish with 220 grit. This becomes your final surface profile for the next stage.
8. Final cleanup. Vacuum/brush, then wipe with a clean cloth. Keep fingerprints off the surface before coating.

Special Cases

If you see random deep lines, stop and rework the previous grit step—jumping ahead won’t remove them.

Pro Tips

• Replace paper when it loads up; clogged sheets can leave random scratches.
• Use lighter pressure as you move finer—pressure tends to deepen scratches.
• Wipe between grits so inspection is accurate.
• Use raking light (flashlight at an angle) to spot leftover deep lines.

Aftercare

• Remove dust from seams and crevices before coating.
• Store unused sheets flat and dry.
• If you wet sanded, dry the surface completely before primer/paint/clear coat.
• Discard sheets that are heavily clogged with paint/finish to avoid re-scratching.

FAQs

• Can I skip a grit? Skipping usually leaves deeper scratches that show up later. Use the full sequence for predictable results.
• How do I know when a grit is “done”? When the scratch pattern is uniform and you can’t find lines from the previous grit under angled light.
• Should I sand in circles? Straight, consistent strokes are easier to inspect. Change direction slightly between grits for clarity.

Watch & Learn

Here are the exact grits referenced in this workflow: 180 grit (pack of 25), 400 grit (pack of 50), 400 grit (pack of 100).

• 180 Grit Sandpaper Sheets — Pack of 25
• 400 Grit Sandpaper Sheets — Pack of 50
• 400 Grit Sandpaper Sheets — Pack of 100

Work one grit at a time, inspect often, and keep pressure consistent. That’s the fastest route to an even finish you can build on.
