Osmo UV Protection Oil Tints (formerly known as Extra) are a range of transparent, lightly pigmented, natural oil based, satin wood finishes for exterior use, similar to the market leading Clear Osmo 420 UV Protection Oil but with a light pigment to further enhance their UV protection. They are 424 Spruce, 425 Oak, 426 Larch, 427 Douglas Fir, 428 Cedar, 429 Natural, 431 Light Cedar, 432 Light Oak. Please note the 429 Natural contains a small amount of white pigment to offset the standard wet appearance of oils but that does mean it is only suitable for light coloured woods and a test area should always be done first.
The microporous surface allows the wood to breathe and reduces swelling and shrinkage. The water repellent surface will not crack, peel, flake or blister. When used as a top coat on already colour treated wood, Osmo UV-Protection-Oil Tints prolongs the renovation intervals significantly. As a single product application, it blocks the greying process on vertical surfaces with a UV protection factor 12 in comparison to untreated wood when two coats are applied. The finish contains active ingredients that prevent mould, algae and fungal attack. Without sanding, simply recoat. Easy and seamless application. Finish stays workable while coating.
Recommended Areas of Use:
Osmo UV-Protection-Oil Tints is ideal for all vertical wood surfaces in outdoor areas: doors, windows, window shutters (dimensionally stable elements), carports, timber cladding, balconies, fences, pergolas, and summer houses (dimensionally unstable elements). Also suitable for bamboo poles (e.g. in screens). For areas that do not meet the requirements of a 15° fall off we would recommend looking at Osmo Natural Oil Woodstain.
Key Product Benefits:
- Very Water and Dirt Resistant
- Contains active Biocide to reduce algae, mildew and fungal attacks
- Reduces Wood Shrinkage and Swelling
- Microporous Breathable Finish that doesn't crack, peel, flake or blister
- No sanding back required when maintenance coat required
- The Pigments give enhanced UV Protection over Clear Version
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. Keep away from direct sunlight or sources of heat.
Wood surface must be clean, dry and frost-free (moisture content max. 20%). UV-Protection Oil Tints is ready to use, please do not thin. Stir well before use. If possible, please apply first coat to all sides before installation.
For renovation works, clean old microporous stains thoroughly – if necessary sand lightly. Clean and restore already greyed or weathered wood at the same time with Osmo Wood Reviver Power Gel. Old paints and lacquers must be completely removed. As a general rule, wear a dust mask during sanding works. Do not sand smooth surfaces finer than grit P120.
The finished surface is influenced by several factors, including the natural characteristics of wood. Therefore, a trial application is always required, especially for unfamiliar surfaces.
Fresh, especially hardwood rich in extractives (natural oils) needs to weather for at least 6-8 weeks after installation. This allows the wood to become absorbent so that the oil finish adheres optimally.
If additional protection against blue stain, rot and insects is desired, pre-treat the wood if possible on all sides with Osmo 4001 WR Base Coat.
Methods of Application:
With a natural bristle, Osmo Flat Brush or Microfibre Roller, apply thinly along the wood grain and spread well. Do not apply at temperatures below 5°C or when the temperature is likely to fall below 5°C during the drying period. As with all waxes and oils the product will become thicker and harder to apply at lower temperatures so if possible we do not recommend applying below 8°C. Do not apply to surfaces above 35°C, take special care with darker surfaces that are fully exposed to the sun.
Allow to dry for approximately 12 hours with good ventilation then apply the second coat. Alternatively the second coat can also be carried out with UV-Protection Oil 420 Extra Clear.
When recoating colour treated surfaces, or for renovation works, one coat applied to the clean and dry surface is usually sufficient.
Cleaning of Tools:
Osmo Brush Cleaner (free of aromatic compounds) is recommended.
Approximately 12 hours (normal climatic conditions, 23 °C & 50% rel. humidity). Lower temperatures and/or higher air humidity can increase the drying time. Allow for good ventilation while drying. The ideal application temperature is 10°C - 35°C.
1 litre covers approx. 18 m² with one coat.
Product coverage depends significantly on the character of the wood. All information refers to smooth and planed/cut surfaces. Other surfaces may lead to reduced coverage.
Depending on the degree of weathering, to retain the appearance apply one maintenance coat of Osmo UV-Protection-Oil Tints to the cleaned and intact finish at least every 2-3 years.
For areas highly exposed to weather, such as weather board, post caps or window cills, 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 surface does not meet these requirements we would recommend looking at Osmo Natural Oil Woodstain.
If the greying process has already begun, restore the surface with Osmo Wood Reviver Power Gel and reapply 2 coats of Osmo UV-Protection-Oil Tints.
To achieve the UV protection factor 12, it is necessary to apply 2 coats of UV-Protection-Oil Tints. With only one coat the life of the coating is significantly shorter. The life will also be reduced when using UV-Protection-Oil Extra 420 Clear for the second coat instead of the pigmented version.
Osmo UV-Protection Oil Tints contains biocides and therefore 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, a permanent protection against algae and fungal attack cannot be provided.
Osmo UV-Protection-Oil Tints Natural 429 protects wood nearly invisibly by containing a small amount of white pigment so it should only be applied to pale European woods and a test area should always be done first. It is designed to preserve the natural wood tone and not enhance the natural colour tone of the wood (no permanent appearance of wet wood) as oils/waxes normally do.
On dark/reddish wood species or dark coloured knots, Osmo UV-Protection Oil Tints Natural is visible as a slightly white chalky surface. A trial application is always recommended.

When applying to softwoods such as Douglas Fir, Pine or Spruce we recommend applying the WR Base Coat 4001 before use.
Oil Rich woods such as Cedar, Iroko, Teak, Walnut, Mahogany etc should be left for at least 12 weeks before application.
Larch should be left to weather for a minimum of 2 weeks before application
None of the UV Protection oils are suitable for flat surfaces or surfaces with less a 15° fall off as the rain will remain on the surface for long periods and pass through the microporous coating.
The maximum moisture content is 20% so products like Green Oak will require several years of drying out before UV protection oils can be applied.
