What is Terrazzo Flooring?

Terrazzo is a composite flooring material made by embedding marble, granite, quartz, glass, or other aggregates in a cement or epoxy resin binder. After installation, the surface is ground and polished to achieve a smooth, reflective, and durable finish.

Key Components

1. Aggregates: Natural stones, glass chips, or recycled materials.
2. Binder: Cementitious or epoxy-based resin that holds aggregates together.
3. Pigments: Optional colorants for customized design patterns.
4. Sealants and Coatings: Applied to protect the surface and enhance gloss.

Types of Terrazzo Flooring

1. Cementitious Terrazzo

• Binder: Cement-based
• Appearance: Matte to semi-gloss finish
• Applications: Heavy-duty industrial areas, public buildings
• Advantages: High durability, sustainable, compatible with underfloor heating

2. Epoxy Terrazzo

• Binder: Epoxy resin
• Appearance: High gloss, vibrant color options
• Applications: Commercial showrooms, airports, hospitals
• Advantages: Chemical resistance, seamless surface, faster installation, and lower maintenance

3. Rustic or Venetian Terrazzo

• Appearance: Exposed, textured aggregates
• Applications: Decorative public spaces, hotels, and art installations
• Advantages: Slip-resistant, unique aesthetic appeal

Installation Process

Proper installation is critical for durability and performance. Terrazzo flooring requires professional expertise to ensure a flawless finish.

Step 1: Surface Preparation

• Ensure the concrete slab is clean, level, and structurally sound
• Repair cracks, voids, or surface imperfections

Step 2: Primer Application

• Apply a primer or bonding layer to ensure adhesion of the terrazzo mix to the substrate

Step 3: Terrazzo Mix Application

• Distribute the terrazzo mixture evenly over the floor
• Control thickness for durability and smoothness
• Embed divider strips for design patterns and joint management

Step 4: Grinding and Polishing

• Use progressively finer diamond abrasives to grind the surface
• Achieve a level, reflective finish and expose the embedded aggregates

Step 5: Sealing

• Apply sealants or protective coatings
• Enhances chemical resistance, stain resistance, and gloss
