Ministry of Land, Infrastructure, Transport and Tourism Construction Specification M-307 Durability of Wood Protection Paint Application, Natural Paint "Osmo Color Wood Stain Protector"
Anyway, it has excellent durability! Feedback from painting contractors who use a lot of Osmo Color. The Osmo Color Wood Stain Protector has a different type of oil. It is made from renewable plant oils (sunflower oil, soybean oil) refined with Osmo's unique technology, which deeply penetrates the wood, bonds with its composition, and protects it. The concept of "protecting wood from the inside" with Osmo Color Wood Stain Protector differs from the mechanisms used by conventional wood protection paints. Furthermore, the ultra-fine pigments used in Osmo Color Wood Stain Protector have a high UV-cutting effect that protects the wood from the outside, preventing damage from ultraviolet rays. Protecting the wood from both the inside and outside is what allows Osmo Color Wood Stain Protector to demonstrate excellent weather resistance on exterior wooden parts. This is achieved by increasing the amount of the main agent (the solid content that adheres to the wood after drying, which consists of plant oil and pigments) in the Osmo Color Wood Stain Protector, resulting in outstanding weather resistance that remains unaffected on exterior wooden parts. In fact, the main agent in Osmo Color Wood Stain Protector contains more than twice the amount found in typical wood protection paints. [A total of 18 colors, including new gray shades introduced in 2017.]
