Safe Environments: Terrazzo Floor Safety

When selecting a floor finish, durability and floor safety should be a priority for any project. People often ask if terrazzo is slippery. This is one of the most-asked questions about terrazzo. When slips, trips, and falls account for many workplace injuries, there is some caution when going all-in on terrazzo flooring.

Is Terrazzo Slippery?

Terrazzo is not inherently slippery. A properly sealed epoxy terrazzo floor achieves a Static Coefficient of Friction (SCOT) of 0.6 or higher, meeting or exceeding ADA recommendations for level surfaces in commercial settings. The final sealer, not the material, determines slip resistance.

Key Considerations:

• Check the manufacturer’s label details that indicate that a floor is non-slippery when wet.
• Without a sealer, stick to lower grit levels for more slip-resistant floors.
• Avoid using waxes or all-purpose cleaners as they contribute to slick surfaces.

Why Floor Safety Matters More than Most Specifiers Realize

Slips, trips, and falls account for over $70 billion in annual costs across U.S. workplaces, and flooring specification is one of the most direct levers available to reduce those risks. For architects designing high-traffic spaces like schools, airports, or hospitals, the floor finish is just an aesthetic decision, but also a risk reduction one.

Terrazzo has a long history of use in high-traffic environments. The question isn’t whether terrazzo is safe, but whether it’s been specified correctly.

What Makes a Terrazzo Floor Slip-Resistant?

The sealer is the single most important safety variable in a terrazzo installation.

Terrazzo is ground and polished to a smooth surface. Without a proper sealer:

• Higher girt levels produce a high-sheen finish that increases slip risk
• Lower grit levels provide a more naturally slip-resistant surface.

With the correct sealer, even a high-polish floor meets safety costs. Always confirm if the sealer carries a UL listing for slip resistance.

What Causes a Terrazzo Floor to Become Slippery?

Three maintenance mistakes turn a safe terrazzo floor into a liability:

• Wax application: Wax adds gloss but creates a slick film over the sealer. It’s recommended to avoid wax altogether.
• All-purpose cleaners: Commercial cleaners can leave behind a residue that increases surface slipperiness over time.
• Improper sealers: Sealers without UL slip-resistance listing may fail safety standards.

Terrazzo floors require periodic resealing. Using compliant products protects both the floor and the building occupants.

Terrazzo’s Maintenance

Speaking of proper care, terrazzo is a low-maintenance flooring system. When spills occur, all it takes is a quick wipe of a mop to soak up the spill without damaging the floor. Always put up wet floor signs when cleaning the terrazzo floor for the day.

Is Terrazzo Safe for High-Risk Populations

Yes, when specified correctly, terrazzo is one of the safest floor finishes for environments serving vulnerable users.

• Children’s Hospitals and Schools: TERRAZZCO’s epoxy terrazzo system, combined with a supporting slip-resistant sealer, creates a safe, seamless surface with no grout lines. Easy for children to walk through a building without tripping.
• Senior Living & Retirement Communities: The non-porous, leveled surface of epoxy terrazzo eliminates trip hazards common with tile or carpet transitions. Terrazzo provides ease of accessibility for the elderly using strollers or wheelchairs.
• Wet Areas (restrooms, kitchens, lobbies): Epoxy terrazzo with an anti-slip sealer meets ADA slip-resistance for both dry and wet conditions.

What are the Other Long-Term Safety Benefits of Terrazzo

• Seamless Flooring: The absence of grout lines eliminates tripping hazards
• Stair Safety: Precast terrazzo stair treads include abrasive strips for additional traction on stairways
• No cracking or chipping: Terrazzo does not develop trip hazards from constant use.
• Bacterial resistance: Non-porous surface resists bacterial growth, reducing hygiene-related risks in healthcare and food service environments.
• Chemical resistance: Terrazzo withstands spills and cleaning agents without surface degradation that would compromise traction.

Conclusion

By getting the sealer right, architects and specifiers can ensure the terrazzo delivers a slip-resistant surface for high-traffic spaces. Terrazzo is a safe floor that combines safety, durability, and design freedom in a single system. As a result, terrazzo delivers high-performance flooring for the life of the building.
