Composite decking has become a popular choice for UK homeowners thanks to its durability, low maintenance and attractive wood-like finish. However, a common concern when considering composite decking is whether it becomes slippery, especially when wet. Understanding the slip resistance of composite decking is important to ensure your outdoor space remains safe for family and guests throughout the year.
The Slip Resistance of Composite Decking
Most modern composite decking boards are designed with textured or grooved surfaces to enhance grip and reduce the risk of slipping. These textures mimic natural wood grain or incorporate anti-slip patterns that provide traction underfoot. As a result, composite decking generally offers good slip resistance compared to smooth materials such as polished stone or tiles.
Manufacturers often test their products to meet specific safety standards related to slip resistance. In the UK, products can be rated according to the Pendulum Test Value (PTV), which measures surface friction. Decking with a PTV above 36 is considered low slip risk.
Factors That Can Affect Slipperiness
Despite its textured surface, composite decking can become slippery if covered with algae, moss, or leaves, especially in shaded or damp areas. Regular cleaning to remove organic build-up is essential to maintain traction.
Certain composite boards may be smoother than others, so it’s advisable to choose products with a proven anti-slip finish if safety is a priority, especially around pools or steps.
Weather conditions also influence slipperiness; ice or frost can make any outdoor surface hazardous, including composite decking.
How to Reduce Slipperiness
Maintaining your composite decking is the best way to prevent slipperiness. Regular sweeping and washing with mild detergent remove dirt and algae. If moss or algae build-up is persistent, using a specialist patio or decking cleaner can help.
In areas prone to dampness, consider installing non-slip decking strips or mats as an added precaution.
In Summary
Composite decking is generally designed to be slip-resistant thanks to textured surfaces and careful manufacturing standards. While it can become slippery if covered in moss or debris, proper maintenance and choosing decking with anti-slip features will keep your outdoor space safe. Taking simple cleaning steps and adding non-slip accessories where needed ensures your composite deck remains both beautiful and secure throughout the year.
