Natural Larch Finish For Exterior Decking
Osmo Decking Oil 009 Larch is specially developed to complement larch decking and other exterior timber surfaces with a warm natural wood tone. The transparent satin finish enriches the appearance of the wood while allowing the natural grain and texture to remain visible.
The pigmented oil finish also provides improved UV resistance compared to clear decking oils, helping maintain the appearance of exterior timber for longer.
Long-Lasting Protection For Exterior Wood
Unlike traditional decking paints and surface coatings, Osmo Decking Oil penetrates into the wood surface to provide durable protection from within. The oil-based formula helps protect timber against moisture penetration, weathering and everyday outdoor wear.
The breathable microporous finish allows moisture to escape naturally, helping prevent peeling, cracking and blistering commonly associated with film-forming coatings and varnishes.
