Osmo Oak UV-Protection-Oil Extra is a satin-matt finish for exterior. It is based on natural oils, is microporous and does not crack, flake, peel or blister. As a stand alone finish, with two coats, it delays the greying process on vertical surfaces by UV-Protection factor 12 in comparison to untreated wood. The finish contains active ingredients which protect it from mould, algae and fungal attack. Easy to renew, no sanding or primer necessary. Easy to apply, will not dry during application.
Product based on natural oil:
Osmo Oak UV-Protection-Oil Extra is based on natura l 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.
Health and environment:
The principle of Osmo to manufacture and supply only products which are safe and environmentally friendly during production as well as for application resulted in the successful certification according to DIN EN ISO 9001:2000 (quality management) and DIN EN ISO 14001
For all vertical exterior woods (dimensionally and non-dimensionally stable): doors, windows and windowsills, carports, timber cladding, balcony, screens & fences, pergolas, garden houses and furniture.
Number of coats required:
