Terrazzo Installation Process

The process of terrazzo installation is an art form that has been passed down through the generations creating master terrazzo artisans. When installing a terrazzo floor there is a set of unique steps that must be followed

  1. The first and most important step in the installation of terrazzo is preparing the surface, which aids in preparing the substrate for a strong bond to the terrazzo mixture. The surface is prepared with a shot blast machine that releases metal shot to remove any residue from the substrate.
  2. The next step in terrazzo installation is crack detailing. This step uses a flexible epoxy that covers any existing crack in the substrate to ensure that these fractures will not rise up into the newly installed terrazzo.
  3. Next, you prime the floor with an epoxy primer to again strengthen the bond to the substrate.
  4. Once the floor is primed, the terrazzo divider strips are put into place and secured. This allows for multiple colors, complex designs, and whimsical patterns to be constructed.
  5. The aggregate, epoxy, and hardener are then mixed together.
  6. Once the mixture is made the artisans begin pouring into the metal forms placed on the floor. In cases where there are multiple colors involved the mixture is transferred carefully into its specific form.
  7. The terrazzo craftsman will either hand trowel or utilize a power trowel to even out the mixture and make sure it is distributed throughout the form evenly. Once level, it is left to cure.
  8. When the floor is cured the artisans will grind the floor with a floor grinder that utilizes pads comprised of diamond plates that are spun at a high velocity, taking the floor texture from rough to smooth ensuring an even and brilliant surface.
  9. Once the grinding process is complete the floor is then grouted to cover any pin holes.
  10. The final step is to hone and seal the floor, giving it extra protection and brilliance to the final product.
  11. Enjoy your one of a kind and unique floor that will last a lifetime!
