Is Composite Decking Slippery?

Is Composite Decking Naturally Slippery?

Composite decking, by design, is not typically as slippery as traditional wood decking. It’s made from a blend of wood fibers and plastic, which generally provides a textured surface that helps prevent slips. However, like any outdoor surface, composite decking can become slippery under certain conditions, particularly when wet. The level of slipperiness varies depending on the type of composite material and the design of the decking surface.

Factors That Affect the Slipperiness of Composite Decking

Several factors can influence how slippery composite decking becomes. The texture of the surface is one of the most significant factors. Many composite decking products are designed with a textured surface that enhances grip, even when wet. The color of the decking can also play a role; darker colors absorb heat and can be less slippery than lighter colors, which may become slicker. Additionally, the level of maintenance the decking receives can affect its slipperiness. Mold, algae, and dirt can accumulate on the surface, creating a slick film that makes it more prone to slipping.

How to Prevent Slippery Composite Decking

To prevent your composite decking from becoming slippery, it’s important to keep it clean and free of debris. Regularly sweeping away dirt, leaves, and other materials that could cause a buildup of moisture is essential. If the deck is exposed to water, especially after heavy rain or snow, cleaning it with a mild soap solution can help remove grime that might contribute to slippiness. Using a deck cleaner designed specifically for composite materials can also help prevent mold and algae growth, which can make the surface slippery.

Choosing the Right Composite Decking for Traction

If you’re concerned about slippage, choosing the right composite decking can make a difference. Some brands offer textured or embossed finishes designed to improve traction, even in wet conditions. When shopping for composite decking, look for products that advertise slip-resistant features or have been tested for traction. There are also composite decking options with anti-slip additives or coatings that enhance grip, making them a safer choice for high-traffic areas or locations exposed to moisture.

Cleaning and Maintaining Composite Decking to Prevent Slipperiness

Regular cleaning and maintenance can help keep your composite deck slip-resistant. Using a pressure washer on a low setting can help remove built-up dirt and grime, but make sure to use the right attachment and pressure to avoid damaging the decking. In addition, treating the decking with a mold and mildew remover can prevent the growth of slippery algae. Some homeowners choose to apply a non-slip coating or deck finish specifically designed to increase grip on composite surfaces. Be sure to follow the manufacturer’s recommendations to avoid damaging the surface or voiding any warranties.

When Does Composite Decking Become Slippery?

Composite decking tends to become slippery when it is wet, particularly in the presence of algae, moss, or mildew. In shaded areas where moisture accumulates, or in areas with high humidity, the surface of the decking can become slick over time. Slipperiness is also more likely to occur in colder months when frost or snow accumulates. To reduce the risk of slipping, it’s important to address any water or debris buildup as soon as possible and consider applying an anti-slip treatment or installing mats in areas prone to moisture.

Maintenance is Key to Reducing Slipperiness

Regular maintenance plays a crucial role in preventing composite decking from becoming slippery. Keeping the surface clear of leaves, dirt, and moss can significantly reduce the chances of slippage. In areas where the deck is often wet—like near pools, spas, or shaded spots—keeping the decking clean and dry as much as possible will help maintain its traction. Cleaning the surface regularly with a composite deck cleaner can help remove any slippery film that might develop.

Effects of Weather on Slipperiness

While composite decking is generally resistant to weathering, extreme weather conditions can still contribute to slippage. Rain and humidity can cause the decking to become slippery, especially in shaded or damp areas where moisture tends to accumulate. Snow and ice can also increase the risk of slipping, so it’s essential to remove these promptly. Use a plastic shovel to gently clear snow off the surface, and avoid using salt or chemical ice melt, as they can damage the composite material.

Anti-Slip Treatments

If you're concerned about slippage, there are anti-slip treatments and coatings available specifically designed for composite decking. These treatments provide an additional layer of grip on the surface, making it safer in wet conditions. Many of these products are clear and won’t alter the appearance of the decking. Be sure to follow the manufacturer's instructions when applying these treatments to avoid damaging the composite material.

Non-Slip Decking Options

Some composite decking brands offer products with enhanced slip-resistant features. These decks may have textured finishes or incorporate additional anti-slip additives during the manufacturing process. If slippage is a major concern for you, consider looking for composite decking options that are specifically designed for maximum traction.

Using Outdoor Rugs or Mats

In areas with frequent moisture or high traffic, outdoor rugs or mats can help prevent slipping. These mats provide additional traction and can also help protect the surface from dirt, which can cause the decking to become slick over time. Just ensure that the mats you choose are designed for outdoor use and allow for proper drainage to prevent moisture from accumulating underneath them.

Consider the Environment

When installing composite decking, consider its location. Decking near a pool, for example, will experience more moisture and be more likely to become slippery than a deck in a dry, sunny area. Similarly, if your deck is located in a shaded area where moisture doesn’t evaporate as quickly, you may want to take additional steps to ensure safety, such as choosing textured decking or adding non-slip treatments.

Summary

While composite decking is generally less slippery than wood, it can still become slippery when wet, particularly in shaded or moist areas. Regular cleaning, proper maintenance, and choosing the right product can help ensure your composite deck remains safe and slip-resistant.
