Osmo offer a large range of UV protection oils with the standard 410 UV Protection Oil, the UV Extra 420 which includes a biocide, the 425 Extra which also includes a light Oak pigment, 428 Extra that includes a Cedar Pigment and 429 Extra Natural that has a small amount of white pigment to retain the look of light coloured European woods such as Oak. Using a pigment will always give you significantly more UVR resistance than just using a clear product. We strongly recommend that a test is always done on a small inconspicuous area first.
