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
- The first and most important step in the installation of terrazzo is preparing the surface, this 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 clean and allow the substrate to bond to the epoxy.
- The next step in terrazzo installation is crack detailing. This step uses a flexible epoxy that covers any existing crack in the substrate floor to ensure that these fractures will not rise up into the newly installed terrazzo.
- Next, you prime the floor with an epoxy primer to again strengthen the bond to the substrate.
- Once the floor is primed the terrazzo divider strips are put into place and secured to the substrate floor. This allows for the use of multiple colors, complex designs and whimsical patterns to be constructed with this type of flooring.
- The magic begins with mixing the aggregates, color matching epoxy resin and the epoxy hardener creating the terrazzo floor mixture that will be transformed into a beautiful work of art.
- Once the mixture is made the artisans begin pouring into the forms placed on the floor. In cases where there are multiple colors involved the mixture is transferred carefully into its specific form.
- 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 for three days.
- When the floor is cured the artisans will grind the floor with a floor grinder that utilizes grinding pads comprised of diamond plates that are spun at a high velocity, taking the floor texture from rough to smooth ensuring an even, smooth and brilliant surface.
- Once the grinding process is complete the floor is then grouted to cover any pin holes.
- The final step is to hone and seal the floor, giving it extra protection and brilliance to the final product.
- Enjoy your one of a kind and unique floor that will last a lifetime!
