Quick Answer

Polishing looks simple but the results depend on the order and the tooling. Abrade with metal-bonded matrix 30–50# to open the surface, refine to 100–200#, densify, then finish with a light resin burnish — the outcome is a speckled, low-mirror finish commercial look. Salt and pepper concrete is a light abrade that exposes the fine aggregate (sand and small stone) evenly across the surface.

About What Salt and Pepper Is

Key points for the polishing sequence.

It's long-wearing, hides wear and is a favorite for retail and commercial floors.

This stage decides how much reflection the floor finally shows.

The Sequence

What matters most in this stage.

Metal-bonded matrix abrading discs do the exposing work, and resin pads set the final sheen.

• Densify — hardens the exposed surface.
• Refine 100–200# metal-bonded matrix — evens the texture, removes coarse scratch marks.
• Light resin burnish 400–800# — a satin sheen; stop before full mirror finish if you want the matte commercial look.
• Abrade 30–50# metal-bonded matrix — removes cream, exposes aggregate evenly.

Miss this step and the gloss will not come up evenly.

How to Control the Look

The practical details.

• Uniform passes — uneven abrading gives patchy exposure. Keep the equipment speed and passes consistent.
• More abrade = more exposure — longer abrading exposes larger aggregate; lighter abrading keeps it sandy.
• Assess area first — the mix design (aggregate size) controls the final look; assess on a corner before committing.

Crews that rush this part rarely get a mirror finish.

Frequently Asked Questions

Q: Which grit exposes the aggregate?

A: For most jobs, 30–50# metal-bonded matrix is the typical exposure grit stage. Finer grit stages refine the texture however don't expose more aggregate.

Q: Do you need salt and pepper cheaper than full polished concrete?

A: In short, In most cases yes — it stops earlier in the sequence (fewer resin stages), saving time and pads.

Q: Can I make salt and pepper glossier later?

A: The practical answer is, Yes — continue the sequence with 800–1500–3000# resin and burnish to convert it to a burnished mirror finish.

Conclusion

Work the sequence completely and the surface rewards you with a clean, bright gloss. Assess first, keep passes uniform, and the speckled commercial look is easy to reproduce.
