Easy and seamless application. Finish stays workable while coating.
Finish contains active ingredients to protect against mould, algae and fungal attack and has proven itself over decades and also under extreme climatic conditions.

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%).
Osmo Natural Oil Woodstain is ready to use, please do not thin. Stir well before use.
Clean old microporous stains thoroughly. Old paints and lacquers must be completely removed. As a general rule, wear a dust mask during sanding works.
If possible, please apply base coat to all sides before installation.
The finished surface is, among other things, influenced by the wood‘s natural characteristics. Therefore, a trial application is always required, especially for unfamiliar surfaces.
If additional protection against blue stain, rot and insects is desired, pre-treat the wood if possible on all sides with Osmo WR Base Coat*.
*Use biocides safely. Always read label and product information before use.
Methods of application
Apply thinly and evenly to the clean and dry wood along the wood grain with Osmo Natural Bristle Brush or Osmo Microfibre Roller and spread well.
Allow to dry for approx. 4-6 hours with good ventilation. After drying, apply a second coat also thinly and quickly.
When renovating, one coat applied to the clean and dry surface usually suffices.
Cleaning of tools
With Osmo Brush Cleaner (free of aromatic compounds).
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. 26 m² sanded wood and approx. 12 m² sawn wood 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.
The transparent colour tone is influenced by the natural tone of the wood and may deviate from the colour chart. Clear finishes offer no UV protection and are therefore not recommended for surfaces exposed to strong sunlight. Dried surface is satin-glossy at first and is afterwards satin. To extend the life of the finish, it is recommended to apply one final top coat of Osmo UV Protection Oil Extra 420 Clear after thoroughly drying. (Not recommended for White 900). Many wood species contain water-soluble coloured extractives which may leach out naturally when weathered. All colour tones can be mixed with each other.
Starting from 2.5 litres per colour tone, available in 186 RAL Classic and 1950 NCS colour tones.
Stains allow the subsurface to shine through. Depending on the wood species, the appearance of the colour tone may deviate from the original RAL/NCS colour tone.
Osmo Natural Oil Woodstain contains biocides and is therefore only to be used on exterior 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.
