Natural wood, and wood treated with normal oil finishes, without UV-protection will begin to grey quite rapidly. Until Osmo UV protection oil was introduced the only effective protection against the effects of UV on exterior wood had been pigmented finishes that obscured the original colour of the wood. Now we can offer Osmo UV-Protection Oil which contains special, clear ingredients which prevent the UV-rays from reaching the wood surface. As long as the rain or water can run off the wood (vertical surfaces) then the UV-Protection Oil effectively prevents the greying process as a stand-alone finish by UV-protection factor 12 in comparison to untreated wood.
The Osmo UV Protection Oil range is based on natural vegetable oils. These natural oils penetrate deeply into the wood, keeping it elastic and healthy, and preventing it from drying and becoming brittle. The wood is allowed to breathe. Moisture can evaporate. Shrinking and swelling are reduced. The Osmo 410 and 420 are clear oils, the 425 and the 428 contain pigments.
Osmo UV Protection Oils are satin-matt, clear finishes for exterior use. They are based on natural oils, they are microporous, and do not crack, flake, peel or blister. When used as a final finish after staining wood, Osmo UV-Protection-Oils prolongs the renovation time significantly.
Osmo 425 (oak), 428 (cedar) and 429 (natural) are based on Osmo 420 UV protection oil but carry pigments to further slow down the greying process. Whenever the wood requires re-treatment applying either of these Osmo oils adds an element of colour to the natural timber with the appropriate pigment.
Osmo 420 Clear UV Oil is a versatile oil that can be applied to most timber and still allow the timber to breath. It has a stain finish and contains biocides that help prevent algae growth, A cleaning and maintenance routine is still recommended to keep the timber and oil in top condition.
