According to the National Terrazzo and Mosaic Association, epoxy terrazzo is the best “thin-set” system available. Today epoxy terrazzo has its advantages over other terrazzo systems. At a nominal 1/4″ or 3/8″ thickness, epoxy terrazzo produces smooth seamless and non-porous flooring that is quick to install, more durable and crack-resistant than other flooring materials, and among the most cost-effective systems on the market today.
Thin-set epoxy terrazzo can cover over existing terrazzo systems like a sand cushion, monolithic, or bonded flooring. Shortly, we’ll address the techniques that go behind applying a new epoxy terrazzo topping.
Before installers can actually pour an epoxy terrazzo mix over the existing surface, they must clean the surface and check for moisture levels. Over the years, terrazzo surfaces encounter different residues that need removal. To start off, installers will remove any sealers or waxes using a shot blaster or terrazzo grinding machine. In addition to removing any flooring residue, an installer wants to check the moisture levels to determine if a moisture mitigation system is needed. Few systems, like bonded terrazzo and sand cushion terrazzo, may hold built-up moisture overtime. These are crucial steps to ensure the thin-set epoxy terrazzo installation is successful, reducing the risk of potential cracking at a later date.
Adding a Membrane
Next, there is a choice whether to add a membrane to the floor or not. Check the NTMA for manufacturers in epoxy thin-set systems for an applicable membrane to use. A membrane is not required only if an existing floor design is intended to be used again in the following installation. While it is not a requirement in some cases, membranes can prevent divider strips from cracking with the new surface. For new designs, we recommend using a floor membrane.
Adding the New Terrazzo Topping
Once the divider strips are in place, installers can now pour the new mixture over the existing flooring. Apply the mixture over the floor, with the aggregate distributed evenly. Allow for the mixture to cure afterward. Once the floor cures, review the flooring for any potential issues. If no issues arise, an installer can apply a protective sealer over the new thin-set epoxy terrazzo floor concluding the installation process.
The old terrazzo floor is now replaced with a thin-set epoxy terrazzo floor.
