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.

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.

Seems to be a high quality product. When applied thinly as recommended takes you long way.

Wow!! This is the best woodcare product I have found anywhere! by Deborah Stanfield

The product was easy to apply and sat on the surface of the wood rather than soaking in too quickly. It gave s lovely rich colour and even finish. It rained just as I finished the job and it instantly repelled the water! Very impressed.

Quite a high gloss finish by Duncan Abbot

I put two coats of this on a bench I have made from sanded reclaimed fir. The initial finish is quite a high gloss. I did not expect it to be quite so glossy and shiny. I was expecting a much flatter finish. It looks good but I have yet to subject it to the rain & the sun and see how the finish responds to the elements. I suspect it is best to give a review in a years time when I can see how it performs in the weather. The stain penetrates with and covers a lot of wood, so you don't need to buy gallons of it. It seems to give a consistent colour across the work piece. My fingers are crossed for how it bears up.

Very Good by C M S

Only just finished using this so not sure how long it will last but absorbs very well. 2 coats to get the semi satin finish. Very expensive especially with super absorbent rough sawn timber. But sheds water and looks very smart.

Really good stuff, exactly the semi-transparent finish and colour we wanted by Simon Clifton

The ranges carried by DIY stores are limited, either 'shed green/brown' or solid 'beach hut' colours. This is a whole different semi-transparent effect, perfect for the high-end yet understated look we wanted for our pergola with the wood grain still visible. The product goes on very thin, so it runs down your arm if you paint overhead with a brush - a mini sponge roller is better. It smells okay (like old fashioned oil based paint used to smell) but takes longer to dry than you might expect. Watching the rain run off in beads after it has dried is very satisfying. Great that it is available in tester sizes, we bought 3 testers, then 3 big tins to do the whole job. It is relatively expensive, but I think value for money. We look forward to watching how it weathers over the next few years.

MUST be stirred thoroughly Seems to penetrate well Attractive natural finish by M Robinson

I have now treated all my garden furniture,some quite old, some brand new. One coat on bare untreated wood produces a lovely matt finish. Second coats slightly glossy giving good cover (also gives even finish over older rubbed back surfaces). Application easy. The finish on older chairs treated with 2 coats and outdoors since late last year remains good.
