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 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 and 429 Natural. 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.
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).
Based on natural plant oils (sunflower oil, soya oil, thistle oil and linseed oil), iron oxide and organic pigments, titanium dioxide (white pigment), siccatives (drying agents) and additives, biocidal active ingredient: Propiconazole. Dearomatized white spirit (benzene-free). EU limit value for this product (cat. A/e): 400 g/l VOC (2010). This product contains max. 400 g/l VOC. Detailed declaration of ingredients available upon request.
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.
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.
Approx. 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.
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.
