What should be pay attention to when making floor terrazzo?

Creating a ground terrazzo involves several steps, and attention to detail is crucial to achieving a high-quality and durable finish. Here are some important considerations when working with ground terrazzo:

1.Substrate Preparation:

Ensure that the substrate (the underlying surface) is properly prepared. It should be clean, dry, and free of any contaminants that could affect the adhesion of the terrazzo.

2.Concrete Mix Design:

Pay attention to the mix design of the concrete or epoxy matrix. The proportions of aggregates, binders, and additives are critical for achieving the desired strength, appearance, and durability.

3.Aggregates Selection:

Choose high-quality aggregates for the terrazzo mix. Aggregates can include marble, glass, quartz, or other materials. The size and color of the aggregates will affect the final appearance of the terrazzo.

4.Color Considerations:

If using pigments or dyes for coloring, ensure consistency throughout the mix. Consider the overall color scheme and design requirements.

5.Installation Technique:

The installation process involves placing the terrazzo mix onto the substrate and then grinding it to expose the aggregates. Pay attention to proper installation techniques, including the thickness of the mix and the use of dividers to create panels.

6.Grinding and Polishing:

Proper grinding and polishing are essential for achieving the desired finish. Use the appropriate diamond grits for grinding to expose the aggregates gradually. The polishing process adds shine and smoothness.


Apply a high-quality sealer to protect the terrazzo from stains and wear. The type of sealer used will depend on the specific terrazzo mix and the intended use of the surface.

8.Maintenance Considerations:

Educate the end-users about proper maintenance. Regular cleaning with mild, pH-neutral cleaners is usually recommended to preserve the terrazzo’s appearance.

9.Expansion Joints:

Consider the installation of expansion joints to accommodate potential movement in the substrate and prevent cracking in the terrazzo.

10.Quality Control:

Implement quality control measures throughout the installation process. This may include checking mix consistency, aggregate distribution, and the uniformity of grinding and polishing.

11.Environmental Conditions:

Consider the ambient temperature and humidity during installation, as these factors can affect the curing and drying times of the materials.

12.Compliance with Standards:

Ensure that the installation complies with relevant industry standards and guidelines for terrazzo flooring.

Always follow the manufacturer’s guidelines and industry best practices for the specific materials and techniques you are using in your terrazzo installation. Consulting with experienced professionals in terrazzo installation can also provide valuable insights and guidance.
