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

Shop-style prep is just repeatable habits: clean, cut, inspect, refine, wipe. This guide sands a hardwood floor (hickory) to screen sand between coats without swirl marks through 120–320 grit using that rhythm.

Pressure decreases as grits get finer.

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 (cut pieces ready)
• Firm sanding block for flats
• Flexible pad for curves
• Microfiber cloths
• Vacuum/brush
• Masking tape
• Optional: tack cloth (after sanding)

Recommended Grit Sequence

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

• 120 grit: reduce pressure each step; swap sheets when cutting slows.
• 150 grit: reduce pressure each step; swap sheets when cutting slows.
• 180 grit: reduce pressure each step; swap sheets when cutting slows.
• 220 grit: reduce pressure each step; swap sheets when cutting slows.
• 320 grit: reduce pressure each step; swap sheets when cutting slows.

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 120 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 150 and 180 grit. Slightly change direction between grits and reduce pressure.
6. Refine with 220 grit. Keep motion steady; avoid sanding in one spot.
7. Finish with 320 grit. This sets your final surface profile for screen sand between coats without swirl marks.
8. Swap sheets as needed. If cutting slows or the sheet loads, change it to keep the scratch pattern consistent.
9. 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.

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: 220 grit (pack of 25), 120 grit (pack of 10), 150 grit (pack of 10).

• 220 Grit Sandpaper Sheets — Pack of 25
• 120 Grit Sandpaper Sheets — Pack of 10
• 150 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.
