Osmo Natural Oil Woodstain is perfect for all exterior woods, including doors, windows & windowsills, carports, timber cladding, balcony, wooden decking, screens & smooth fences, pergolas, summer houses and garden furniture.

  • All colour shades can be mixed with each other to create any number of alternative colours
  • We can mix to a specific RAL shade. Use this RAL chart and input reference under "Special Instructions" at checkout, allowing a minimum of 10 working days. RAL matched colours are made to order and are therefore non-refundable

Please be advised that 125ml tins are printed in German only. For application instructions refer to the overview below.

Before opening the 5ml sample sachets, squeeze the packet several times to ensure that the oil and pigments inside are thoroughly mixed.

Ensure surfaces to be treated with Osmo Woodstain are clean, dry and frost-free prior to application (moisture content max. 20℃).

  • Existing oil finishes should be lightly sanded and cleaned before application
  • Existing coatings such as paint and varnish must be fully removed by sanding or stripping back to bare wood
  • Remove sanding dust thoroughly from the surface with a brush or vacuum cleaner before application
  • Use white spirit to degrease and remove surface contaminates if required
  • Fill any holes or gaps with Osmo Exterior Gap Sealer
  • Revive any greyed or sun damaged wood with Osmo Wood Reviver Gel (6609)
  • 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 (4001)

Always do a small test area before starting any project and follow the manufacturer's instructions on the tin at all times. Stir thoroughly before and periodically during application.

  1. Apply Osmo wood stain thinly and evenly along the wood grain with an Osmo Soft Tip Brush or Osmo Premium Microfibre Roller and spread well
  2. Work the oil into the surface grain of the wood
  3. If possible, apply the first coat to all sides of the wood before installation to offer the best all-round protection
  4. Wipe off any excess oil from the surface of the wood with a clean, lint-free cloth
  5. Allow the first coat to dry fully
  6. Apply a second coat using the same method as the first

Please Note: Rough sawn timber is more absorbent, meaning coverage per litre will be greatly reduced.

The dried surface is initially satin-gloss at first and is afterwards satin. The transparent colour tone of the finish will be influenced by the wood's natural colour, causing the result to deviate from the colour shown on the colour chart. Lightly pigmented (coloured) transparent finishes have little protection against UV influences and are therefore not recommended for surfaces prone to strong sunlight.

  • To increase the durability of the finish, we recommend applying a top coat of Osmo UV Protection Oil Extra (420)
  • For the white Osmo Natural Oil Woodstain finish (product code 900), use Osmo UV Protection Oil Extra (429) as a top coat as this will retain the white finish. Using the standard clear UV protection oil (420) on top of the white 900 may result in a creamy or 'off-white' finish

Regular Cleaning

For the regular cleaning of exterior wooden surfaces, use Osmo Exterior Spray Cleaner (8027).


If surfaces show signs of wear or a loss of weather resistance over time, simply clean and add a maintenance coat of Osmo Natural Oil Woodstain to the existing finish.

Probably the best wood finish that I've ever used by Steve Holland

I have used this on my weather worn wooden gazebo which has spent 12 years outside in all weathers. It has given it a new lease of life and it looks as good as new. The wood is now a lovely colour and is water repellent after 2 coats.The oil was easy to apply, it brushed out well and the colour went on very evenly. I would recommend this product and will certainly use it again in the future.

It does what it says on the tin but coverage is half quoted amount by Andrew Burrow

Good deep pigmentation. Easy to apply but use the large brushes recommended by supplier. It is too liquid for normal brushes. The supplied brushes cost buttons compared to the wood stain and cut application time by 2/3rd. I have imported such stain from Denmark. These Scandinavians know how to protect wood. This osmo product is more liquid than the Pinotex I got in Denmark. Less coverage rate. More adsorption into the wood. Who knows if that is just the solvent or the preserving oil. But you cannot get Pinotex oil based woodstain/paint in the UK. The Osmo seems great for rough planking and planed timber.

Excent result by T Crawley

Took a while to realise how thinly each coat should be applied to ensure the grain and character of the wood appeared. Quick and easy to apply with roller then brush finish for best results. grey looks really great with the redwood shiplap timber and that satin finish works perfectly, delighted with the end result and has attracted a lot of favourable comments.. Job done.

Fantastic wood protection from a truly "green" product by Graeme Martin

I discovered the superior quality of Osmo oils and wax-based wood products when refinishing the oak floors in my cottage. Low volatiles and reasonably fast drying times mean minimum time disruption; in addition the product is extremely easy to apply and leaves a flawless finish attainable by any competent amateur. I won't use any other product on wood from now on.

As long as the product lives up to its claim then it will be worth every penny of its higher cost against its competitors. It goes on easy and looks good. My wood was suffering from sun exposure but after three coats looked as good as new with a nice shine.
