Navigating the world of outdoor decking, a common question we often encounter is, "Is composite decking slippery?" It's a valid concern, especially if you're wanting a safe and inviting outdoor space.

Our extensive experience with composite decking has shown us that while composite decking is usually slip-resistant, certain factors can still make it slippery, such as ice or snow.

In this article, we'll delve into the intricacies of composite decking, exploring its slip-resistant qualities and offering insights into how you can maximize safety and enjoyment in your outdoor haven.

What this article covers:

Is Composite Decking Slippery When Wet?

After putting it to the test and diving into extensive research, the answer is a bit more nuanced than a simple yes or no. Generally, modern composite decking is designed to be more slip-resistant than traditional wooden decks, especially when wet.

A prime example of this is our anti-slip decking, which is designed to not get slippery when wet. Water generally also doesn't cause composite decking expansion or composite decking warping. However, certain conditions can affect its slipperiness.

Why Could Composite Decking Be Slippery?

Texture And Quality

The texture and quality of composite decking are pivotal in determining its slip resistance. In our experience, the latest generations of composite decking are engineered with advanced textures – think finely embossed wood grains or subtle ridges.

These textures are specifically designed to enhance grip, even when the surface is damp. This is a significant leap from older or lower-quality composites, which often feature smoother finishes that can become perilously slick in wet conditions.

It's not just about the aesthetics; the texture of your decking plays a crucial role in ensuring safety.

Dirt And Debris

The accumulation of dirt, leaves, and debris is an often-overlooked factor contributing to slipperiness. When these elements gather on your decking, they create the perfect breeding ground for mould and algae.

These organisms not only discolour and damage the decking material but also create a slimy layer that can be treacherously slippery. This is why regular maintenance is not just a recommendation but a necessity.

A routine sweep and occasional deep clean can drastically reduce the risk of slips and falls, keeping your decking both visually appealing and safe.

Weather Conditions: Ice And Snow

Although composite materials resist moisture better than traditional wood, they're not immune to winter weather. Ice and snow can form a slick layer on the surface, posing a hazard. However, it's worth noting that the risk can be mitigated with proper care.

For instance, using a plastic shovel instead of a metal one to remove snow can prevent surface damage, and applying ice melt products designed for composite decking can help manage ice buildup.

It's all about adapting your maintenance routine to the seasons to ensure your decking remains a safe space year-round.

How To Prevent Slippery Composite Decking

Regular Cleaning

Keeping your composite decking clean is not just about maintaining its good looks; it's a crucial step in preventing slipperiness. Over time, things like leaves, dirt, and pollen can settle on your deck.

If left unattended, these can lead to the growth of mould and algae, which are notorious for making surfaces slippery.

The solution? A simple routine of sweeping and washing. Regularly sweeping your deck keeps the majority of debris at bay, while a thorough wash a couple of times a year can do wonders.

You don't need fancy equipment for this – a basic garden hose or a gentle pressure washer will do the trick. Remember, a clean deck is a safe deck!

Choose The Right Texture

When it comes to picking out your composite decking, think about texture as your secret weapon against slipperiness. The market is full of options, but what you're looking for are decking boards that have a bit of a grip to them, such as our grooved decking.

This could be in the form of raised wood grain patterns or subtle ridges. These textures help your feet get a better grip, especially when the surface is wet. So, take your time to feel the textures and choose one that offers both style and safety.

Proper Installation And Maintenance

The way your decking is installed can have a big impact on how slippery it gets. Good drainage is key. Make sure your decking has enough space underneath for water to flow away.

In our experience, this prevents water from pooling on the surface, which can be a slip hazard. In the winter months, ice and snow need special attention.

Avoid using metal tools to remove snow, as they can cause composite decking scratches and damage to the decking. Instead, opt for a plastic shovel or a broom. And if you're dealing with ice, use a calcium chloride-based ice melt, which is safe for composite materials.

Regular checks for any wear and tear, and fixing any issues promptly, will also keep your decking in top shape and less likely to become slippery.


While composite decking can be slippery under certain conditions, choosing the right product and maintaining it properly can significantly reduce this risk. At Ovaeda, we've seen firsthand how the right composite decking can provide a safe, durable, and beautiful outdoor space.
