Vertical Wood Surfaces
Yes, but only for vertically structured surfaces such as cladding, fencing, doors etc. Osmo UV-Protection Oil contain special ingredients which resists UV rays from the sun to a factor of 12 in comparison to untreated wood.
UV-Protection Oil requires a minimum drip angle of 15°C to offer a suitable resistance.
Horizontal Wood Surfaces
Horizontally structured surfaces such as decking and uncovered garden furniture, allows rain to remain on the wood surface for potentially long periods of time, thereby reducing the UV resistance significantly, to the extent that we do not recommend using a clear finish on these types of surfaces unless a naturally greying effect is desired over time.
For the best UV protection for wood decking, we recommend a slightly tinted wood colour from the Decking Oils range.
