Osmo Garden Colour 2.5L - Anthracite Grey

Osmo Garden Colour is an opaque, water-based exterior finish designed for wooden surfaces in gardens and outdoor spaces. It provides long-lasting protection with a microporous formula that resists water and dirt and helps prevent cracking, peeling, flaking, or blistering. Suitable for a wide range of exterior timber projects—such as timber cladding, clapboards, fencing, pergolas, garden furniture, sheds, balconies, and car ports—the coating is biocide- and preservative-free and formulated with a high VOC content. It emphasizes external durability with excellent weather and UV resistance, while delivering the convenience of two coats potentially completed in a single day. Coverage and drying details vary with wood type, but the product typically covers about 16 m² per litre per coat, with a drying time around 3–4 hours under normal conditions. Appropriate ventilation during drying is recommended to ensure proper curing.
