Quick Answer

The standard polishing ladder runs 50#, 100#, 200#, 400#, 800#, 1500# and 3000#. Coarse grits (50-200) cut and level, mid grits (400-800) refine the scratch pattern, and fine grits (1500-3000) produce gloss. Never jump more than one step per pass, or the previous scratches will not fully remove.

Why Grit Order Matters

Each grit size leaves scratches at a fixed depth. The next finer grit only removes the scratches left by the previous one. Jumping from 50# straight to 400# leaves deep 50# scratches that 400# cannot cut through - they stay visible as long grey lines in the finished floor.

The Full Grit Ladder

• 50# - coarse metal or hybrid bond: levelling, coating removal, first cut
• 100# - removes 50# scratches, starts smoothing
• 200# - smoothing phase, removes 100# marks
• 400# - honing begins; surface starts to feel smooth
• 800# - removes 400# haze, slight sheen appears
• 1500# - polishing phase; gloss becomes visible
• 3000# - high-gloss step before burnishing

How Many Steps Do You Actually Need?

• 3-step system (50/100/200 + 400 + 1500): fast, industrial-looking satin finish
• 5-step system: adds 800 and 3000 for a semi-gloss
• 7-8 step system: full 50-3000 ladder for high-gloss floors

How to Know When to Move to the Next Grit

Move up when the current grit stops cutting and the scratch pattern looks uniform. Check with light from a low angle: if you still see directional scratches from the previous step, stay on the current grit longer. Change direction with each grit so marks cross each other.

Frequently Asked Questions

Q: Can I skip the 100# step?

A>Skipping works only if the previous grit was fine enough to remove. In general, one-step jumps are the safe rule.

Q: Is 3000# always needed?

A>No. For a satin or matte finish, stop at 400# or 800#. 3000# only adds gloss.

Q: Resin or metal pads for the coarse steps?

A>Use metal or hybrid bond for 50-200# because they cut faster; resin pads are for 400# and finer.

Q: What if I see scratches after 3000#?

A>They are probably from a skipped step or contaminated pads. Re-hone at 800# and work back up.

Conclusion

Follow the ladder one grit at a time, change pads before they glaze, and let the scratch pattern guide your progress. A disciplined sequence is the difference between a hazy floor and a reflective one.
