OSMO 420 Outdoor UV-Protection Oil – Clear 2.5L

Clear, satin wood finish based on natural oil for wood in outdoor areas. Microporous surface allows the wood to breathe and reduces swelling and shrinkage. Waterrepellent, will not crack, peel or flake. As top coat on already color treated wood, Osmo UVProtection Oil Extra prolongs the renovation intervals significantly. As a single product application, it blocks the graying process on vertical surfaces with a UV protection factor 12 in comparison to untreated wood when two coats are applied. Osmo UV-Protection Oil Extra is furnished with active ingredients to protect the coating against mold, algae and fungal attack. Simply apply without sanding. Easy and seamless application. Finish stays workable while coating.

RECOMMENDED USE
Osmo UV-Protection Oil Extra is ideal for all vertical wood surfaces in outdoor areas: doors, windows, window shutters (dimensionally stable elements), carports, wood siding, balconies, fencing, pergolas, and sheds (dimensionally unstable elements). Also suitable for bamboo poles, for example, in fencing.

STORAGE
Up to 5 years and longer if can is kept dry and closed tightly. If thickened by frost, store for 24-36 hours at room temperature before use.

SURFACE PREPARATION
Wood surface must be clean, dry and frost-free (moisture content max. 20%). Clean old microporous finishes. Remove previous layers of varnish. The finished surface is influenced by several factors, including the condition of the wood. Therefore, a trial application is always recommended, especially for unfamiliar surfaces.

DIRECTIONS FOR USE
Osmo UV-Protection Oil is ready to use. Do not thin. Stir well before use. With Osmo Hand Brush or Osmo Microfibre Roller, apply thinly along the wood grain and spread well. Allow to dry for approx. 12 hours under good ventilation. Then apply the second coat as before. When recoating color-treated surfaces, or for renovation works, one coat applied to the clean and dry surface is usually sufficient. Ensure the surface has been cleaned prior to application.

COVERAGE
2.50 Liter will cover approx. 480 ft² with one coat. Coverage will vary depending on the type, age and texture of the wood.

NOTE
Oils enhance the natural tone of wood. Depending on the degree of weathering, apply one coat of Osmo UV-Protection Oil Extra to the cleaned and intact finish after approx. 3-4 years. For areas exposed to strong weathering, such as weatherboard, post caps or window sills, please expect significantly shorter renovation intervals. Vertical elements mounted onto horizontal wood should have at least a 15 degree angle. Sharp edges must be rounded (radius > 2 mm). If the greying process has already begun, degrey the surface with Osmo Wood Reviver Power Gel and refinish with 2 coats of Osmo UV-Protection Oil Extra. To achieve the UV protection factor 12, it is necessary to apply 2 coats of UV-Protection Oil Extra. With only one coat on untreated wood, the life of the coating is significantly shorter. Due to high oil content, the coating has a light yellowing effect when used as a top coat on white substrates. Therefore, we recommend using Natural Oil Woodstain 900 White as a top coat in such cases. Osmo UV-Protection Oil Extra is furnished with biocides and therefore it is only to be used in outdoor areas. The added active ingredients delay or minimize the risk of algae and fungal attack. For effective protection, two coats are to be carried out. In accordance with the latest technical research, permanent protection against algae and fungal attack cannot be provided.
