The slip resistance of any wooden decking, including Accoya, depends on several factors such as weathering, surface profiling, coatings, wetness, and ongoing maintenance. Like other timber products, the build-up of biofilm (such as algae or fungi) can also affect how slippery boards feel if not cleaned regularly.

Generally speaking, Accoya performs comparably to unmodified wood species with equivalent surface finishes, profiles, and treatment conditions. With the right profiling and regular maintenance, Accoya provides a safe and stable surface that performs well around pools and wet environments.
