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

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.

Perfect coverage, fast shipping. AAA+++

Ok but expensive by Cms

Only just applied it so no idea how long it will retain colour. Sinks into wood but on rough sawn cladding does not go very far, as the advertising points out. If it lives up to its forecast then I am happy with it but it is, per sq m, very expensive compared to others.

Fantastic and prompt advice from the team at Wood Finishes Direct Speedy delivery Great service by Francoise Malbos

As always with previous experiences of OSMO products. Perfect. The advice I was given to stain the floor of my log cabin with a product for external usage followed by 2 coats of OSMO Polyx oil, was spot on. I will use the log cabin as potting shed and workshop so there will be a fair amount of traffic with muddy boots. Can't wait to sweep and mop to test the finish.

Worth every penny by Tony Lee

I've used various colours over the years and, despite the price, there is, in my opinion no other similar product that comes close in terms of ease of application and, more importantly, longevity.
