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

Use a simple checklist after every grit: wipe clean, inspect under angled light, and only move up when the scratch pattern is uniform. This workflow sands a hardwood floor (hickory) to screen sand between coats without swirl marks through 80–220 grit.

Checks prevent rework.

Why Sanding Matters

Sanding removes defects and creates the surface profile for the next stage. Deep scratches left behind can show through after paint, clear coat, or polishing. A controlled progression makes finishing predictable.

Recommended Tools

• Sandpaper sheets
• Sanding block/pad
• Flashlight for raking light inspection
• Microfiber cloths
• Vacuum/brush
• Masking tape

Recommended Grit Sequence

Use the sequence below in order. Inspect between steps and only move up when older scratches are removed.

• 80 grit: checklist = uniform scratches before moving up.
• 120 grit: checklist = uniform scratches before moving up.
• 150 grit: checklist = uniform scratches before moving up.
• 180 grit: checklist = uniform scratches before moving up.
• 220 grit: checklist = uniform scratches before moving up.

Step-by-Step

1. Protect adjacent areas. Tape trim, edges, and nearby surfaces you don’t want to scuff.
2. Clean first. Remove oils and dust so the paper cuts evenly.
3. Start with 80 grit. Use even strokes and a block where possible to avoid waves.
4. Wipe and inspect. Confirm one consistent scratch pattern before moving up.
5. Step up through 120 and 150 grit. Slightly change direction between grits and reduce pressure.
6. Refine with 180 grit. Keep motion steady; avoid sanding in one spot.
7. Finish with 220 grit. This sets your final surface profile for screen sand between coats without swirl marks.
8. Final cleanup. Vacuum/brush, then wipe with a clean cloth before the next stage.

Special Cases

If a deep scratch appears late, drop back one grit step and remove it before continuing.

Pro Tips

• Swap sheets when they stop cutting; clogged paper can leave random scratches.
• Reduce pressure as grits get finer.
• Wipe between grits so inspection is accurate.
• Use a block on flats to avoid finger grooves.
• Before moving up, scan under angled light for any lines from the previous grit.

Aftercare

• Remove dust from seams and corners before coating.
• If wet sanded, dry fully before primer/paint/clear coat.
• Store unused sheets flat and dry.
• Discard heavily loaded sheets so old finish doesn’t re-scratch the surface.

FAQs

• Can I skip a grit? Skipping often leaves deeper scratches that show later. Use the sequence for predictable results.
• How do I know when to move up? When the scratch pattern is uniform and you can’t find lines from the previous grit under angled light.
• Why does the finish still look uneven? Usually because the first grit step wasn’t completed or debris re-scratched the surface.

Watch & Learn

Here are the exact grits referenced in this workflow so you can match the sequence: 180 grit (pack of 10), 220 grit (pack of 10), 320 grit (pack of 10).

• 180 Grit Sandpaper Sheets — Pack of 10
• 220 Grit Sandpaper Sheets — Pack of 10
• 320 Grit Sandpaper Sheets — Pack of 10

Complete each grit step, inspect under angled light, and keep pressure light at the end. That’s the simplest route to a finish-ready surface.
