The installation process for both epoxy terrazzo and traditional terrazzo involves several steps to achieve a seamless and durable flooring surface. Here’s a breakdown of the installation process for both types:

Traditional Terrazzo Installation

  • Substrate Preparation: Ensure the substrate is clean, level, and properly primed to promote adhesion.
  • Aggregate Placement: Spread the chosen aggregates evenly across the substrate, ensuring proper coverage.
  • Cementitious Binding: Pour the cementitious matrix over the aggregates, filling any voids and ensuring a smooth surface.
  • Grinding and Polishing: Use diamond grinding equipment to grind the surface to the desired level of smoothness, followed by polishing to enhance its luster.
  • Sealing: Apply a penetrating sealer to protect the terrazzo surface from stains and moisture infiltration.

Epoxy Terrazzo Installation

  • Aggregate Blending: Mix the chosen aggregates with the epoxy resin binder, ensuring thorough encapsulation.
  • Pouring or Installing: Pour the epoxy aggregate mixture onto the prepared substrate or install precast tiles, ensuring proper alignment and spacing.
  • Leveling and Troweling: Use tools to level the epoxy mixture and eliminate air bubbles, ensuring a flat and uniform surface.
  • Curing: Allow the epoxy terrazzo to cure for the recommended time to achieve optimal strength and durability.
  • Grinding and Polishing: Similar to traditional terrazzo, use diamond grinding equipment to grind and polish the surface to the desired finish.

Both installation processes require skilled labor and attention to detail to achieve a flawless terrazzo flooring system that meets the project’s specifications and design objectives.

Durability Factors

Both epoxy terrazzo and traditional terrazzo are renowned for their exceptional durability, making them ideal choices for high-traffic areas subjected to heavy wear and tear. Traditional terrazzo’s durability stems from the chemical reaction between the aggregates and cement binder, resulting in a dense and resilient surface. 

Epoxy terrazzo, on the other hand, relies on the bond strength of the resinous binder to hold the aggregates together, offering enhanced resistance to stains, impacts, and moisture intrusion.
