How to Install Terrazzo Floor
Terrazzo floor is installed either in-situ or tiles.
1. Prepare the surface
The top layer of concrete is removed from the top surface so that a strong bond is created between concrete and terrazzo. Any presence of cracks is filled on the concrete surface. The floor is leveled and any presence of moisture is removed by moisture mitigation system.
2. Use divider strips as per design
Place Divider strips to separate colors, design, and control of expansion joints.
Mix the terrazzo using mixing equipment and according to specifications.
Created with epoxy and hardener.
4. Pour terrazzo
Add epoxy to the flooring surface and using a trowel, spread the epoxy and distribute additional aggregates like marble chips and glass pieces over the floor.
- Allow the floor to cure
- After the floor is cured, use a grinding machine to smooth the floor.
- Apply grout mixture if any pinholes are present.
- Polish and apply a sealer as per supplier’s directions.
Terrazzo tile flooring is similar to installing ceramic tile by using adhesive and grout system.
