Wood type and application method can vary coverage.

Osmo Natural Oil Woodstain is a semi-transparent exterior wood stain containing natural oils and UV filters to protect against the greying affects of sunlight whilst offering excellent protection against rot, mildew and weathering.

Ideal for all exterior woodwork including decking, it's easy to apply, enhances the wood grain and texture and dries to a satin-matt finish.

The clear Osmo UV Protection Oil Extra (420) can be mixed with any Osmo Natural Oil Wood Stain colour if a lighter shade is required.

Be aware that rough sawn timber is more absorbent, meaning coverage per litre will be greatly reduced.

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

RAL Colour Matches Should you wish to opt for a non-stocked shade, please supply the specific RAL shade reference number using this RAL chart under "Special Instructions" at checkout, allowing a minimum of 10 working days. RAL matched colours are made to order and are therefore Non-refundable.

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

Note: The clear version of this product (701) does not offer any UV-Protection and is therefore not recommended for surfaces prone to strong sunlight. If a clear finish with UV protection is required, consider Osmo UV Protection Oil Extra.

Wood surfaces must be clean, dry and frost-free prior to application. Osmo Natural Oil Woodstain is ready to use straight from the tin with no need to thin.

This product should be stirred thoroughly before use and periodically during application. If possible, apply the first coat to all sides of the wood before installation to offer the best all-round protection.

For additional protection against mould, algae, dry rot, woodworm and insect attack, use a good quality wood preservative such as Ronseal Total Wood Preservative or Barrettine Premier Wood Preservative prior to applying Osmo Natural Oil Woodstain.

Osmo WR Base Coat 4005 protects against blue stain and rot but doesn't contain an insecticide.

Note: It's important to allow the specified drying time of any preservative before applying this product.

Always do a test area first

Apply thinly and evenly along the wood grain with either a good quality hand brush or Microfibre roller, and spread well. Allow for good ventilation whilst drying. Apply a second coat as before. The final surface quality is dependent on the woods surface structure. We therefore always recommend to test the product on a small sample area before complete application.

When renovating, simply apply one coat of Natural Oil Woodstain to the clean and dry existing finish, this will usually be sufficient.

Application brushes and other equipment can be cleaned with white spirit.

Can be stored up to 5 years or more if the original tin is full, tightly closed and stored in a dry place. If product becomes thickened by frost it will regain its normal consistency under normal temperatures within 24-36 hours.

To preserve any oil that is left over, pour the remaining product into a smaller container such as a tin, jar or bottle and fill to the rim so there is no or minimal air in the container. Protect the stored oil from temperature extremes of heat and cold.

  • Keep out of the reach of children.
  • Avoid contact with skin and eyes. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
  • May produce an allergic reaction.
  • If swallowed, seek medical advice immediately and show this container or label.
  • Use only in well ventilated areas.

Warning: Wash out any used cloth impregnated with this product immediately after use or store in an airtight container (danger of self-ignition).

Drying time is approximately 12 hours depending on temperature and humidity. If applied correctly (thin coats) it is normally touch dry in 4-6 hours. Lower temperatures and/or high humidity can increase the drying time.

Note: 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.

The dried surface gives a light satin finish at first but will change to a satin-matt finish thereafter. To increase the durability of the finish we recommend, after thorough drying, to apply a top coat of Osmo UV Protection Oil Extra.

For the white Osmo Natural Oil Woodstain finish (product code 900) use Osmo UV Protection Oil Natural - 429 Extra 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.

All colour shades can be mixed with each other to create any number of alternative colours if required

A note from us...

Hello Mrs Parkinson-Tait,

Thank you for the feedback ! We always recommend test areas with products, especially colours and the wood that you are applying to can have an impact on the colour achieved. I hope that you got the finish you where looking for an dif there is anything further that I can help with please do let me know.

Kind Regards Sam.

Fantastic product by Gil Schalom

Having used the clear deck oil before, I wasn't sure how it was going to cover our beautiful hardwood deck. It was worth the gamble as it still provides the right degree of transparency while giving extra UV protection. The additional fungicide ingredients will also be a benefit.

It makes my door like new by Xia Liu

I used OSMO Natural oil woodstain Light oak for the final coat of a oak door refurbish. The colour is exactly what I want although it looks lighter in the picture on the website. I would say from my experience that it is better to test the colour before the application. Giving a four star is because the drying time is longer than what is said on the tin. In my case, applying the product at end of September, it takes around two days for the first coat to touch and feel not so sticky. I did have a few nervous days wondering what if the coating fells sticky forever...

Applies really well, looks great by Stephen D

I used this to paint the cladding on my house. I wanted something that would look good and lasts. On reviewing my options this product stood out and did not disappoint. It was also available in different colours, so I could move away from the normal selection. Plus I liked the fact it helped enhance the existing colours in the wood. It is more expensive than your basic alternatives but in my opinion highly worth it. It applied really well and the finish is superb. I am really pleased.

Excellent Oil Based Woodstain by David A Hood

Coverage will vary dependent on the condition of the wood. Important to frequently stir the tin to ensure the stain is mixed with the oil otherwise it will disperse to the bottom of the tin. To avoid waste do not to overload the brush. Yes its time consuming but the results are worth it.
