Wood surface must be clean, dry and frost-free (moisture content max. 20%).
Osmo Natural Oil Woodstain is ready to use. Do not thin. Stir well before use.
If possible, please apply the first coat to all sides before installation.
Clean old microporous stains thoroughly. Old paints and lacquers must be completely removed. As a general rule, wear a dust mask during sanding works.
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.
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.


With Osmo Flat Brush or Microfibre Roller, apply thinly along the wood grain and spread well.
Allow to dry for approx. 4-6 hours under good ventilation. Then apply a second coat.
For renovation works, one coat applied to the clean and dry surface is usually sufficient.


Transparent colours are influenced by the natural colour of the wood and therefore they may deviate from the sample colours. Light transparent colour tones offer only limited UV protection; therefore they are not recommended for surfaces exposed to strong sunlight. Dried surface is at first satin-glossy and then satin. To extend the life of the coating, 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.
Transparent finishes allow the substrate 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 is furnished with biocides and therefore it is only to be used in outdoor areas.
The added active ingredients delay or minimise 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.

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.
