How to Create a Salt and Pepper Polish Finish on Concrete Floors



๐ŸŒŸPolished concrete flooring is a smart and sustainable choice for industrial and commercial spaces. One of the most popular and refined finishes in the market today is the Salt and Pepper finish — known for its speckled appearance, durability, and low maintenance.

In this post, we’ll walk you through the complete process of achieving a Salt and Pepper polished concrete floor, suitable for warehouses, factories, and commercial buildings.


๐Ÿงฑ What is Salt and Pepper Concrete Finish?

The Salt and Pepper finish is a polished concrete surface where the top layer is lightly ground to expose small aggregates (typically 1–3 mm in size). These particles resemble salt and pepper sprinkled across the surface, creating a refined and elegant speckled look.

Unlike heavy grinding methods that expose large stones, Salt and Pepper finishes keep the exposure shallow for a more subtle aesthetic.


๐Ÿ”ง Tools and Materials Required

  • Concrete grinder & polisher

  • Diamond pads (30 to 3000 grit range)

  • Industrial vacuum cleaner

  • Concrete densifier (lithium or sodium-based)

  • Concrete sealer or guard

  • Water for wet polishing (optional)


๐Ÿ—️ Step-by-Step Process

1. Surface Preparation

Begin by thoroughly cleaning the floor. Remove any dust, paint, adhesives, or contaminants. Repair cracks or surface imperfections using a patching compound.

Tip: Surface preparation is key to achieving a uniform and long-lasting finish.


2. Initial Grinding (Salt & Pepper Exposure)

Use a 30 or 50-grit diamond pad to remove the top surface layer (known as the cream) and begin exposing the fine aggregate.

  • The goal is to lightly expose the sand and small stones — not to cut too deep.

  • This step defines the final Salt and Pepper pattern.


3. Densification

After initial grinding, apply a concrete densifier. This hardens the concrete surface by chemically reacting with the free lime content.

  • Use a sprayer to apply evenly.

  • Let it soak for 30–45 minutes.

  • Mop or vacuum excess material.


4. Progressive Polishing

Now start polishing with finer grits of diamond pads:

  • 100 → 200 → 400 → 800 → 1500 → 3000 (optional for ultra-high gloss)

Each step makes the surface smoother and more reflective.

  • Use wet polishing if needed to reduce dust.

  • Vacuum or clean thoroughly between grit changes.


5. Sealing or Guard Application

Once polishing is complete, apply a penetrating sealer or concrete guard. This helps protect the surface from stains, moisture, and wear.

  • Sealer also enhances surface sheen and improves cleanability.


6. Final Buffing

Use a high-speed burnisher to buff the sealed surface. This adds depth and shine to the polished floor, giving it a clean and finished appearance.
