410 Clear SatinEnhances the natural character of the wood. Supports a healthy living environment without the use of biocides to ensure the dry finish is safe for humans, plant and animal.UV Protection:
*Please note that there is currently a transition of labels due to the introduction the Osmo Tinting System with new colour possibilities. It is possible that slight variations to the sticker on the front of the product label may occur depending on point of purchase.
The clear finish has been developed to enhance the natural character of the wood.
Remember, the wood’s natural colour and character will influence the final result. Please always trial apply!
Transparent colours for UV-Protection Oil 410 are available when mixed in selected stores, via the Osmo Tinting Machine.
These transparent colours were developed to appear in harmony with their respective wood species e.g. 426 Larch for Larch wood projects. The wood’s natural colour and character will influence the final result. Plus, the darker the transparent colour finish, the stronger the UV-resistance.
Please always trial apply!

Wood surface must be clean, dry and frost-free (moisture content max. 20%). Ideally, surfaces are sanded no finer than a P120 grit grade of sand paper. Sanding to finer grades will reduce required absorbency.
Do not thin. Stir well using a flat stirring stick or spatula before use. If possible, and if the wood is an absorbent species, please apply the first coat to all sides before installation.
Fresh wood containing natural wood ingredients /extractives (eg: Cedar, Larch, Teak, Mahogany or Iroko) are often less absorbent and need to weather off first before applying the product. Please refer to website ‘Suitability’ section for more details. Weathering helps ingredient rich wood become more absorbent and the wood finish adheres optimally. Weathering is also required if ingredient rich wood has been freshly sanded or renovated.
A coloured base coat is recommended, e.g. Natural Oil Woodstain. Coloured base coats can improve UV protection.
For renovations, clean old microporous wood finishes thoroughly. De-grey any weathered bare wood with Osmo Wood Reviver Power-Gel before applying an Osmo exterior product.
Old paints and lacquers must be completely removed. As a general rule, wear a dust mask during sanding works. To maintain absorbency, avoid sanding surfaces finer than a P120 grit. Weather ingredient rich wood after sanding.
The finished surface is influenced by several factors, including the condition of the wood. Therefore, a trial application is always required, especially for unfamiliar surfaces.
Soft wood species like Pine or Spruce are more prone to blue stain, rot and insects. If desired, pre-treat these soft woods if possible on all sides with Osmo WR Base Coat.
With Osmo Flat Brush or Osmo Microfibre Roller, apply thinly along the wood grain and spread well.
Allow to dry for approx. 12 hours. Cooler temperatures, higher humidity levels or over application will delay drying. Once dry, apply the second coat thinly.
When recoating colour treated surfaces, or for renovation works, one coat applied to the clean and dry surface is usually sufficient.
Oils enhance and intensify the natural tone of wood (permanent wet effect).
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.
Osmo UV-Protection-Oil is best suited to vertical structures whereby there is plenty of water run-off. For areas exposed to strong weathering, such as flat horizontals, 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, de-grey the surface with Osmo Wood Reviver Power Gel and refinish the dried surface with 2 thin coats of Osmo UV-Protection-Oil Extra.
To achieve the UV protection factor 12, it is necessary to apply 2 thin coats of UV-Protection-Oil Extra. With only one coat on untreated wood, the life of the coating is significantly shorter.
Using power washers will severely decrease the coverage of the finish and general or multi-purpose cleaners will increase the frequency of maintenance and recoating.
Regular Cleaning: Damp cleaning with Osmo Spray-Cleaner or diluted Osmo Decking Cleaner .
Occasional Maintenance: If necessary, intensive cleaning and refreshing using Osmo Wood Reviver Power Gel or Osmo Gard Clean.
Recoating: Simply re-apply one thin coat onto the clean and dry surface when signs of wear become visible.

For all other wood types not mentioned, always trial apply first.
For the following wood types, WR Base Coat is recommended before use.
For the following ingredient rich wood species, a weathering period is recommended to improve absorbency. New or freshly sanded ingredient rich wood requires at least 12 weeks exposure to the exterior elements ( unless otherwise stated below) before application.
After the weathering period, it’s generally recommended to de-grey the bare surface with Osmo Wood Reviver Power-Gel , damp rinse, then clean the surface from the extractive content before application, always trial apply!
For all other ingredient-rich hardwood species not mentioned, please contact us for further information.
Important: please check and ensure moisture content is below 20% prior to application.
Made with high quality synthetic bristles with soft tips which gives fine control in achieving the desired effect. Exceptional coverage capacities which produce professional looking results every time. Available in 25, 50, 60 and 100 mm sizes.
Microfibre roller and 60mm natural bristle brush set to ensure high coverage allowing you to apply thinly, thoroughly and evenly along the wood grain and spread well. For first application, two coats is recommended onto a clean and dry surface. For renovation, just one coat is necessary.

Additional Information:
All exterior woods grey into a patina colour over time, but UV-Protection Oil has been developed to slow the greying process by (UV factor) 12 times in comparison to untreated wood. Wood colour will fade over time. To maintain some colour for longer, consider transparent coloured options from Osmo like UV Protection Oil Tints or Natural Oil Wood Stain.
Ideal for windows, doors, cladding, fencing and other vertically structured joinery (not recommended on flat surfaces such as decking).
Natural oil-based and microporous finish does not crack, flake, peel or blister. Water and dirt resistant, moisture regulating and reduces wood swelling and shrinkage.
