How to sand a terrazzo floor?

Terrazzo is a material appreciated for its beauty and durability, but it requires professional treatment to reveal its full brilliance. Here are the detailed steps for a perfect result.

Cutting and rough grinding: preparing the surface

The first step is to level the surface and eliminate major irregularities.

Tip: work methodically to cover the entire surface evenly.

Grouting: filling imperfections

Grouting is used to fill small holes and cracks in terrazzo.

  • Apply a suitable grouting product, then remove the excess using Falkor 3-Round Grit 100 Tools.
  • Ensure the surface is smooth, free of scratches or excess material.

Sanding: achieving a perfect surface

Sanding is a gradual process to remove scratches and create a smooth surface.

Mineralization: hardening the terrazzo

Mineralization strengthens the surface and prepares the terrazzo for optimal shine.

  • Apply Concrete Hardener Lithium on a clean surface.
  • Allow it to dry for 24 hours to ensure effective penetration and hardening.

Mechanical polishing: revealing the shine

A mechanical shine is achieved through progressive polishing with diamond pads.

  • Use MPMS Hybrid Pads in the following grit sequence: 200, 400, 800, 1500, and finally 3000.
  • This step is essential for preparing the surface to achieve a mirror-like finish.

Waterproof and oil-repellent protection: preserving terrazzo

  • Apply Giordex Béton to make the surface waterproof and oil-repellent. This nanotechnology-based treatment ensures durable protection.
  • Once dry, apply Concrete Guard Lithium to reinforce protection.

Mirror shine: the final touch

For a mirror-like shine:

  • Use a high-speed polisher (1300 RPM) equipped with a hybrid diamond pad Grit 3000.
  • This final step enhances the brilliance and hardness of the surface.

Maintenance: preserving the shine

Regular maintenance ensures the longevity and beauty of your terrazzo:

  • Clean daily with Giordasol Pierre and a microfiber cloth.
  • This product protects against dirt while maintaining the shine.

By following these steps, you’ll achieve a perfectly sanded, durable terrazzo with exceptional brilliance. Adopt this method for professional results every time!
