Why timber decking can become slippery
Timber is naturally porous, which means it absorbs water. Combined with shade, poor airflow and fallen leaves, this creates a perfect environment for algae and mildew. Surface growths, along with general dampness, reduce friction and create a slip hazard, especially in high-traffic or low-light areas.
Steps you can take to prevent slips on your decking
Tackle causes before treating symptoms
The first step is to keep your deck clean and well-maintained. Regularly sweep away leaves and debris, and wash down the surface to prevent mould and algae buildup. Ensure good drainage and airflow around the structure to help the wood dry quickly after rain. These small steps go a long way in improving grip and extending the life of any anti-slip treatments.
Using non-slip coatings on your decking
Simple to apply, but needs upkeep
Non-slip coatings are one of the easiest ways to improve surface grip without changing the natural look of your decking. These products contain abrasive particles that create texture underfoot. To apply, clean your deck thoroughly and make sure it is completely dry. The coating should be re-applied regularly, especially in areas that get the most use, to maintain its effectiveness over time.
Fixing anti-slip plates to your decking
Durable and long-lasting protection
Anti-slip plates offer a more permanent solution. Made from tough, textured materials, metal plates are screwed directly into the decking surface. They provide excellent grip in all conditions. While they do change the look of your deck, they are highly effective. Many people choose to use them on steps or other high-risk areas rather than across the whole deck.
Installing DeckWright inserts
Add grip without spoiling the aesthetic
DeckWright Inserts are designed to improve safety while keeping the natural timber aesthetic intact. Specially developed strips can be fixed into existing deck grooves, offering strong grip with a subtle appearance. They are easy to install and ideal for walkways, steps or larger areas where safety is a priority. Once in place, they last for the lifetime of your decking.
Choose the right anti-slip decking
In-built grip for long-term peace of mind
If you're installing new decking or replacing boards, it makes sense to consider anti-slip products from the start. Fountain Timber supplies Millboard Lasta-Grip decking, which features a textured surface designed for maximum grip without the harshness of grit-strip boards. It offers excellent anti-slip performance with a clean, high-end finish.
We also stock Gripsure anti-slip timber boards, combining natural wood with two strips of hardened aggregate for lasting slip resistance. Backed by a 15-year performance warranty, these boards are ideal for both domestic and commercial use where year-round safety is important.
