Terrazzo, a timeless and durable flooring option, is often used in both residential and commercial settings due to its longevity and aesthetic appeal. But the question remains: does terrazzo need to be sealed? The short answer is yes, terrazzo should be sealed, and here's why.
Understanding Terrazzo
Terrazzo is a composite material made of chips of marble, quartz, granite, or other materials set in a matrix of cement, resin, or other binding agents. It's known for its strength, durability, and the ability to create unique, custom designs. However, like any other flooring material, terrazzo requires proper care and maintenance to ensure its longevity and beauty.
Why Seal Terrazzo?
Sealing terrazzo serves several purposes:

- Protection from Stains: Terrazzo is porous, meaning it can absorb liquids and stains. A sealant creates a barrier, preventing this absorption and making it easier to clean.
- Enhances Appearance: Sealing terrazzo can enhance its natural beauty by bringing out the colors and patterns of the chips used in its creation.
- Prevents Moisture Damage: In areas prone to moisture, sealing terrazzo can help prevent water from penetrating and causing damage to the subfloor or the terrazzo itself.
Types of Sealers
There are several types of sealers available for terrazzo, each with its own benefits:
| Sealer Type | Benefits |
|---|---|
| Acrylic Sealers | Easy to apply, cost-effective, and provide good stain resistance. |
| Epoxy Sealers | Offer excellent chemical resistance and durability, but can yellow over time. |
| Urethane Sealers | Provide good stain and abrasion resistance, and are suitable for high-traffic areas. |
When to Seal Terrazzo
It's best to seal terrazzo as soon as it's installed and cured. However, if your terrazzo is already installed and not sealed, it's not too late. Regular cleaning and inspection can help you determine when it's time to seal your terrazzo.
Signs that your terrazzo needs sealing include:

- Water no longer beads on the surface.
- Stains are difficult to remove.
- The surface appears dull or faded.
Sealing Terrazzo: A Professional Job
While it's possible to seal terrazzo yourself, it's often best left to professional terrazzo contractors. They have the experience and tools to ensure the job is done correctly, maximizing the lifespan and beauty of your terrazzo.
In the world of flooring, terrazzo stands out for its durability and beauty. With proper care, including regular sealing, terrazzo can last for decades, retaining its charm and functionality. So, the next time you ask, "Does terrazzo need to be sealed?" remember the answer is a resounding yes.
