Can I use Terrazzo outside?
Yes, terrazzo can be used outdoors, but only when the correct type of terrazzo is specified and installed properly. Outdoor environments place different demands on flooring compared to interior spaces, including exposure to moisture, temperature changes, and foot traffic. Because of this, not all terrazzo products are suitable for external use.
What Type of Terrazzo Is Best for Outdoor Use?
For external applications, cement-based terrazzo is almost always recommended. Cement terrazzo allows moisture to escape naturally, reducing the risk of trapped water and damage over time. It also performs better in changing weather conditions, including freezing temperatures.
The aggregates used in outdoor terrazzo are typically harder stone types, such as granite or quartz, which improve durability and slip resistance. The surface is usually finished in a honed or textured finish rather than polished, helping to improve grip underfoot.
Selecting the correct terrazzo system is essential for long-term performance, and professional advice should always be sought before specifying outdoor terrazzo.
Is Outdoor Terrazzo Slip Resistant?
Slip resistance is a key consideration for any outdoor flooring. Outdoor terrazzo can be made slip resistant through the use of appropriate finishes and aggregate selections.
Honed, textured, or brushed finishes provide better grip than polished surfaces and are commonly specified for patios, steps, and walkways. In addition, anti-slip treatments can be applied to further enhance safety, particularly in areas exposed to rain or moisture.
When designed correctly, outdoor terrazzo meets safety requirements without compromising on appearance.
