The Osmo UV Protection Oil Tints are transparent (not clear) and lightly pigmented with a satin finish in addition they contain active ingredients to help prevent mould, algae and fungal attack. Each of the products contains a light level of pigment designed to match the timber, the 429 Natural contains a small amount of white pigment designed to help maintain the appearance of pale European woods rather than the wet look that oils normally create, however because wood can vary so significantly and everyone has different expectations of the finish they are looking for we strongly advise that a test area is always applied first, all the products come in 5ml sachets and 125 ml test pots for this purpose. The Osmo UV protection oils are based on natural oils and are microporous so do not crack, flake, peel or blister and do not require sanding back when an additional coat is required. When used as a final finish after staining wood, Osmo UV Protection Oil prolongs the renovation time significantly. As a stand alone finish, with two coats, it prolongs the greying process on vertical surfaces by UV-Protection factor of at least 12 in comparison to untreated wood. Easy to renew, no sanding or primer necessary, they are asy to apply and will not dry during application. The range all contain coloured pigments designed to enhance the colour and provide greater UV protection, if a lighter colour is required they can be applied as a single coat and then over-coated with 420. We strongly advise that a test area is done on an off-cut or inconspicuous area prior to any application to ensure that the colour and finish are what you are looking for.
Osmo UV-Protection-Oils are based on natural vegetable oils. 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 and no sanding back is required for any future applications.
