How To Install A Terrazzi Sprayable Microcement Floor?

Installing a polished concrete floor is a specialized task that can significantly enhance the appearance and durability of your space. The Terrazzi Sprayable Microcement System introduced by Duraamen offers a seamless and efficient solution for achieving a high-quality polished concrete surface. This blog will guide you through the process as demonstrated in their latest instructional video.

Advantages of Using Terrazzi Sprayable Microcement

  • Increased Efficiency: The sprayable system covers large areas quickly, drastically reducing the time needed compared to traditional trowel applications.
  • Flawless Finish: Eliminates trowel marks and smoothing lines, ensuring a smooth, uniform surface without imperfections.
  • Cost-Effective: Reduces labor costs as fewer installers are needed, and large areas can be covered efficiently.

Step-by-Step Installation Guide

  1. Preparation: Ensure the substrate is clean and meets the necessary strength requirements, especially when applying over gypsum (minimum of 3500 psi).
  2. Application: Use the Terrazzi Concrete Sprayer to evenly distribute the microcement. One person sprays while another broadcasts the aggregate.
  3. Curing and Polishing: Allow the microcement to cure fully, typically over 24 hours. Then, polish the surface using a swing buffer equipped with a 100-grit honeycomb diamond pad.
  4. Sealing: After polishing, clean the surface thoroughly before applying a topcoat or sealer like Perdure U90 for enhanced durability and finish.

Visual Aesthetics

The finished floor boasts a traditional polished concrete look with a subtle, natural salt and pepper coloration, ideal for modern and minimalist designs.

Additional Benefits

  • Versatility: Suitable for renewing old, worn concrete by hiding imperfections with a thicker application if necessary.
  • Gypsum Compatibility: Can be applied over gypsum substrates that pass the hardness test, expanding the system’s usability.
