Osmo Natural Oil Woodstain is perfect for all exterior woods including doors, windows and windowsills, carports, timber cladding, balcony, wooden decking, screens and 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.

  • 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
  • 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 Osmo Natural Wood Stain thoroughly before and periodically during application. Wood surface must be clean, dry and frost-free (moisture content max. 20℃). If possible, apply the first coat to all sides of the wood before installation to offer the best all-round protection.

  1. Apply Osmo wood stain thinly and evenly along the wood grain with a brush or microfibre roller, and spread well
  2. Work the oil into the surface grain of the wood
  3. Wipe off any excess oil from the surface of the wood with a clean, lint free cloth
  4. Allow the first coat to dry fully
  5. Apply a second coat using the same method as the first

Please be aware that 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 woods 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.

Regular Cleaning

If wooden surfaces develop signs of mould or algae, we recommend cleaning with an appropriate exterior wood cleaner.


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

Very happy with this product by Susan Riley

Excellent product for adding some colour but still allowing the grain to show through.

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.

Easy to apply by Wayne Bowden

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.

Excellent durability against the Scottish weather by Robert Ian McCallum

I would always use this product rather than cheaper quality brand ones on the market. It may be expensive, but lasts years longer on exterior applications than its rivals.

Excellent product I used on my new soft wood garden gates by Clive Bagshaw

I wanted and oil based woodstain as my new drive/ garden gates were of softwood and my builder advised using an oil based product rather than sovlent/water based. My gates are 9ft wide by 6ft high and the 2.5lt can was enough to apply 3 coats and there is still enough left for another coat at least. The light oak colour gave exactly the colour finish I was looking for. Product arrived within 3 days of ordering with text notification confirming deliver day/ times. Excellent service.

Excellent product for external wood that needs reviving by David Marsh

I purchased this product for the treatment of Canadian cedar that is 10 years old. I was slightly sceptical as the normal advice is not to paint Canadian cedar, but it's natural colour had faded with age. The result was excellent, although a second coat might be advisable for a perfect finish. May be considered expensive, but worth the investment.

The oak porch way looks like new by Mrs S Cohen

This has to be the best product I've ever used. The advice received from Wood finishes direct was second to none. Our oak porch now looks like it the day it was fitted. Will definitely use it again and I've already been singing the praises of all the helpful, friendly staff at Wood Finishes Direct. A pleasure to be a customer. Thank you.br
