Natural Protection For Exterior Decking
Osmo Decking Oil is specially formulated to protect exterior wood without hiding the natural texture and character of the timber. The penetrating oil-based formula nourishes the wood from within while helping reduce moisture absorption and weather-related damage.
Unlike traditional decking paints and surface coatings, Osmo Decking Oil will not crack, peel or blister over time. The breathable finish allows moisture to escape naturally, helping maintain the stability and appearance of exterior timber.
Designed For Larch & Exterior Timber
The transparent Larch 009 tone has been developed to complement the natural appearance of larch timber decking while adding rich colour and enhanced UV protection. Darker pigmented decking oils provide increased resistance against UV greying compared to clear finishes.
Suitable for use on both smooth and grooved decking boards.
