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.

Given the phenomenal performance Osmo is good value! by Gazebo

Yes, it's a seemingly devilish price but no other matt finish "varnish" comes close.

Marvellous service by Justin Griffiths

I knew this product was excellent anyway, but I ordered it very close to Christmas and wasn't expecting delivery until after the holiday period. But it arrived the next day despite the usual postal nightmares!!!! 10/10 to these guys for their rapid service. :)

Finish was good, but coats left a tacky feel to surface. Container was covered in German writing. I need a translator to decipher what was said on the tin.

You really do need to spread it thinly by Stephanie Fry

Covers well on dry wood. Had to make sure wood was very low MC to get proper adherence. It does cover well thinly, need to persevere and not slop it on!

Very easy to apply by Mrs TJEllis

I bought six 'raw' finish bamboo chairs to replace ones that I'd had for years, & I wanted to show the grain & not cover it with a painted look. I have completed 5 now and varnished them for a smooth feel.

Incredible opacity, without doubt the best by David Noakes

I was sceptical at first when recommended to use Osmo Natural Oil Wood Stain, mainly due to the price, as other quality brands are cheaper, however after receiving my order next day delivery, I set out on treating my new log cabin. The cabin is 5m x 3m and I have completed a brilliant finish with just one 2.5L tin. I am so happy with the product that from now on I will only use Osmo for treating and staining timber.

Fantastic product and worth every penny by Tara Noble

I am thrilled with the finnish and the colour was lovely, still allowing you to see the natural grain in the wood. Although this product is more expensive than others it is worth it. I found it easy to apply, and it went a long way. I found this supplier the cheapest and they delivered free of charge and quickly.
