1. Folasaga
The Osmo UV-Protection Oil Extra 420 Clear is a clear, satin wood finish designed for exterior wood surfaces. This natural oil-based product offers advanced UV protection, helping to preserve the natural beauty of wood while preventing graying. Its microporous surface allows the wood to breathe, reducing swelling and shrinkage, and it is water repellent. This finish will not crack, peel, or flake, and when used as a topcoat on already color-treated wood, it significantly extends renovation intervals.
