Terrazzo Overlay

Save Time and Money with Terrazzo Overlay


Because terrazzo can be poured over most surfaces, contractors can save on cost and time to demolition a floor and pour a new concrete slab. It can be poured directly over an existing surface as long as the underlying substrate is strong and structurally sound. The only situations where a terrazzo overlay shouldn’t be poured over an existing floor is when the floor is a soft material like carpet, vinyl or VCT, and when a tile is loose or broken.


Pouring epoxy terrazzo over existing flooring is fast and easy. Installers can trowel the material one day, let the terrazzo cure overnight, and polish it the next day. Because epoxy terrazzo contains zero VOCs with no off-gassing it is safe to keep facilities open for business while the installation is ongoing.


In addition to its easy installation, pouring epoxy terrazzo over the existing surface is environmentally-friendly. This process prevents discarded floor materials from ever reaching landfills and avoids energy use and silica dust exposure.


So the next time you are determining whether you have room in your budget to include epoxy terrazzo flooring, ask yourself “Can it be poured over the current substrate?” In doing so, you can cut construction costs making room in your budget for a terrazzo floor that will last the lifetime of any building structure.

Can Epoxy Terrazzo Be Installed Over Existing Terrazzo?


Yes, epoxy terrazzo can be poured over an existing cement or epoxy terrazzo floor. Terrazzo is a good investment for building owners looking for a flooring system that is built to last. Thin-set epoxy terrazzo has advantages over other terrazzo systems including crack and stain resistance properties, flexible designs, and lower maintenance costs. Here are some situations where a building owner may replace an existing terrazzo floor with a new epoxy terrazzo floor.


  • Cement terrazzo is porous and epoxy terrazzo is nonporous. As a result, cement terrazzo is more susceptible to staining. In historical buildings, owners are finding existing cement terrazzo floors beneath carpet coverings. Owners cited that the carpet glue had soaked into the cement terrazzo floor and the stains were difficult to remove. Because epoxy terrazzo is nonporous, it is resistant to chemicals and stains; therefore, a building owner can hire a contractor to pour epoxy terrazzo over the cement terrazzo without having to demolish the floor.


  • If the building owner wants to rebrand their business with a new logo or artistic design, they can hire a contractor to pour epoxy terrazzo over the existing surface.


  • If the building owner wants to change an outdated appearance with a fresh and trending terrazzo finish, they can hire a contractor to update the floor design without having to remove the existing surface first.
