Porcelain tile is one of the most durable and aesthetically pleasing materials for outside use, and it’s gaining in popularity. The material is naturally low maintenance and nearly indestructible. Because the surface seems so smooth, people often ask, “Is outdoor porcelain tile slippery?” Of course, no tile is slip-proof, but outdoor porcelain tile is manufactured to be slip-resistant.
Outdoor porcelain tile is actually designed for safe, non-slip use in areas that tend to get wet: around pools, on patios, walkways, and other paved areas. Made from fine clay and fired at high temperatures, the dense, sturdy material is highly resistant to water absorption and freezing, so it tolerates most weather conditions.
Porcelain tiles also offer a wide array of designs, so you can create a more distinctive look based on your personal style. The tiles can mimic any stone or wood — even metal. Take your pool surround to the next level or dress up a drab walkway. Give a mediocre patio some pizazz. Because porcelain tiles are also fade resistant, they will retain their color and fashionable style, even in harsh sunlight.
What makes porcelain tiles slippery?
Several factors may affect whether or not a porcelain tile will be slippery, including the texture of the tile, wear and tear, contaminants on the surface, and weather conditions.
Most important, the porcelain tile’s texture must be designed for outdoor use. Indoor porcelain tile tends to be much smoother than outdoor tile, offering much less traction. Outdoor porcelain is made with a texture to grip for enhanced safety.
Over time, heavy foot traffic and exposure may gradually wear down the textured finish of outdoor porcelain tiles, reducing slip resistance. But most manufacturers guarantee performance for several years, so check the product warranty.
Surface contaminants, such as leaves, algae, dirt and other debris accumulating on outdoor tiles can also make them slippery, especially when wet. Be sure to keep the tiles clean to avoid a dangerous slip and fall risk.
Of course snow or ice can make any outdoor surface slippery, creating hazardous conditions. Stay off the tiles in winter weather or clear them thoroughly to ensure safety.
Outdoor porcelain tiles are slip resistant
All porcelain tile created for outdoor use is designed with slip-resistant technology. During production, manufacturers add texture, grooves, or other enhancements to improve traction and avoid slips and falls.
You’ll notice that most outdoor tile tends to be matte rather than polished or glossy, since shinier finishes are often slippery.
DCOF slip resistance ratings
It’s important to consult the manufacturer’s details regarding DCOF (Dynamic Coefficient of Friction) ratings before embarking on an outdoor porcelain tile installation. These ratings indicate that the tile has been tested for slip resistance. The higher the number, the more slip resistance the tile offers.
Keep in mind that ratings will vary depending on the texture and finish of the tile. This chart gives a general idea of the different levels of slip resistance and appropriate applications for using porcelain tile outdoors based on DCOF ratings.
| DCOF Rating | Slip-Resistance Level |
| 0.42-0.49 | High Resistance: Appropriate for areas around pools, walkways, patios — anywhere the tiles will be used when wet. |
| 0.36 – 0.41 | Moderate Resistance: May be used for patios and walkways, but won’t provide as much slip resistance as the high resistance category. Not recommended around pools or other high moisture areas. |
| 0.35 and below | Minimal Resistance — Tiles may not be suitable for outdoor areas with exposure to water or rain. May be useful for a covered patio or three-season porch protected from the elements. |
Using non-slip porcelain tiles outdoors
To ensure the highest level of safety and to get the best use of your outdoor porcelain tiles, follow these essential installation tips.
• Choose high quality, high performance tiles designed for outdoor use with sufficient slip-resistance ratings. This is the most important factor for optimal safety and long-term enjoyment of your outdoor space.
• Ensure proper drainage. Pay close attention to water in the area where you plan to install your tiles. If water pools or washes across the area in heavy rains, you will need to install a drainage system to minimize water on the tile surface and minimize risk.
• Apply anti-slip treatments and coatings to enhance the porcelain tile’s slip resistance. Be sure to follow manufacturer instructions carefully. These treatments may wear off over time, so pay close attention to recommendations for reapplication.
How to keep porcelain tiles clean to avoid slips
Proper maintenance can also help you get the most from your outdoor tiles. It’s imperative to keep your porcelain tiles clean and free of debris to get the best possible performance. Keep a close eye out for the formation of algae, which can be especially slick and slippery.
Because porcelain is so dense and hard, it naturally resists dirt and other contaminants, minimizing mold and moss growth on the tiles. This not only keeps the tiles looking good, but also makes maintenance easier.
Here are a few additional tips for keeping your outdoor tiles clean and safe.
•Prevent damage to the porcelain tile’s surface texture by using mild cleaners and non-abrasive tools. Follow your manufacturer’s instructions to keep your outdoor tile at peak performance.
•Consider placing outdoor rugs or mats in high-traffic areas to provide extra traction and reduce risks of slips and falls. Mats and rugs can also trap dirt to help minimize tracked-on debris, keeping your porcelain tile cleaner.
•Encourage friends and family to use appropriate footwear in outside spaces with porcelain tile. Shoes with smooth soles and high heels, for instance, can put people at greater risk for slips and falls, especially in wet areas.
Slip-resistant porcelain tiles offer beautiful and stylish options for pool surrounds, patios, walkways, and other outdoor spaces. They can turn ugly concrete or a grassy space into a stunning design element. For use outdoors, where water or rain could be an issue, it’s important to choose an appropriate DCOF rating to ensure optimal safety. Always refer to the manufacturer details and instructions for proper use.
