Top tips for better grip...
Wooden decking in shady or damp areas can become green, slimy and slippery in winter. Clean them regularly with a proprietary decking cleaner such as Ronseal Decking Cleaner and Reviver (£13.50 for 5L) Use boards with good treads or specific non-slip boards. These tend to have a deeper, more textured profile (ridges) Treat boards with a non-slip wood treatment, such as Cuprinol Anti-Slip Decking Stain (£25 for 5L) or Watco Decksafe (£80 for 5L) Use anti-slip decking inserts, which add grip and are easy to fit retrospectively, such as Anti-Slip Watco Decking Strips (from £16.56).
