Osmo UV-Protection Oil Extra Satin 420E 10L

Osmo UV-Protection Oil Extra is a premium natural oil-wax formulated for exterior timber surfaces that require maximum protection against UV degradation and weathering. The Extra formula provides enhanced UV filter strength compared to the standard UV-Protection Oil, making it the preferred choice for timbers in full sun exposure or south-facing elevations.

The satin finish enhances the natural colour and grain of the wood while providing a durable, microporous surface that allows the timber to breathe. It is highly resistant to water, dirt, and UV-induced greying, significantly extending the life and appearance of exterior cladding, fences, garden furniture, and decking surrounds.

The 10L trade size is ideal for large-scale projects and professional applicators. Coverage is approximately 8–12 m² per litre per coat depending on timber porosity, with two coats recommended for new or bare wood.
