How is a terrazzo floor installed?

Basic steps to installing a terrazzo floor include surface preparation, mixing components for a terrazzo floor, troweling, grinding and polishing, and sealing a terrazzo floor.


Surface preparation is necessary as this allows installers to create a strong bond between substrate and terrazzo. Installers will perform crack detailing and floor leveling as well. Concord Terrazzo Company provides TERRAZZCO Brand epoxy products that aide in the surface preparation process such as TERRAZZCO Moisture Mitigation System MMS 950, Flexible Membrane 528 and Leveling Fill.


Once the surface is prepared, installers can begin forming the layout of the terrazzo design by cutting and placing divider strips across the surface.


For epoxy terrazzo, part A epoxy resin is combined with a part B epoxy hardener. Approximately 200 pounds of aggregates and marble dust is added and allowed to mixed thoroughly. The batch is then carried to a designated spot and poured in place. Using a hand trowel, installers spread the terrazzo evenly at the desired thickness.


Installers will next grind the floor to create a more smooth and more refined appearance. Any pinholes left after the grinding process are covered with epoxy grout of the same color. This ensures a uniformed and non-porous surface is established.


Polishing brings out the vividness of the epoxy colors and aggregates, adding a good shine to the surface. Sealer is applied for protection of the terrazzo floor, which concludes the installation.

What can i do to prevent cracks in my terrazzo floor?
