Osmo Anti-Slip Decking Oil Clear (430D) is a natural oil-wax finish for exterior wood decking with an integrated anti-slip additive, providing a safer surface underfoot in wet conditions. The 2.5L size is the trade buy for larger decking areas. The clear formula allows the wood to grey naturally over time while delivering Osmo's proven penetrating oil protection against water, dirt, and UV.

Based on natural oils and waxes, it penetrates the wood rather than forming a surface film, so it won't crack, peel, or flake.
