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

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.

It is Osmo, and in my opinion, THE best product for wood finishing by Red Baron

The protective finish embedded within the oil woodstain solution yields a brilliantly smooth satin factory finish. I can hardly wait to use the Osmo Polyx Spray oil finish on my next project using my hvlp Fuji spray system.

Looks a bit orangey when tested but lovely when all fences are painted by Steve Sutherland

The testers are useful to gauge how dark/light the stain colour is but you really need a bigger pot to test fully. The colour is perfect for the effect we want and it's quite easy to apply. I would recommend painting the fences with a roller at first. Get two coats on and then touch up with a brush if necessary. This will save you hours or brush painting!
