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

Not found better over many years by DalesDecorator

Pricey, but stores well in 750 ml cans and convenient to use and reuse; coats sparingly, looks great with little effort and has formidable lifespan in Yorkshire weather.

Great product by OSMO by Mrs K Smith

Easy to apply, good depth of colour which lets the beauty of the grain of the wood show through the stain.

Relatively expensive - but well worth it by Richard S

I had not used (or heard of!) Osmo Natural Oil Woodstain until our painter & decorator recommended it for use on our new garden furniture - and I am pleased he did. The initial extra cost was well worth it, the stain did the job superbly - and has amazing water-repellent qualities, it is fascinating to see how rainwater simply stands on the surface! I can certainly recommend the product, and would use it again.

Good product by Andrew

Very pleased so far -- I bought this product recently to stain an exterior door and window frame, and it has given a pleasing finish. I've been looking for a oil woodstain to make maintenance easier and avoid having to sand back cracks and blisters, as with traditional varnishes. Time will tell how it lasts. Good coverage

Too Small a Sample by John Mortimer

I bought a 750 tin on the WFD recommendation of the product. The sample gave a different finish to the larger tin.

A note from us...

Hello John,

Thank you for taking the time to write a review for us. We have had a couple of customer say the same thing and it is improtant to manipulate the sachet in your hands for around 5 to 10 mins to ensure that all the pigment is evenly mixed throughout the oil. Also spend some time stirring the oil with in the tin for the very same reason.

Feel free to get in touch if you have any questions.

Kind regards Sam.

First time user Appears strange as it's translucent finish is nothing like I have used before by Steve Naxton

The finish takes a little getting used to but it certainly is easy to apply. It's growing on me!!!

Easy to apply but coverage advice is totally wrong for 1st coat on new timber by Gareth Potter

The coverage advice for this product should be reduced by 50% when applying to new weathered timber.

Happy with product by Philippa Shepherd

We had sprayed our fence with dark brown wood oil based protector and hated it. 2 coats of Basalt Grey, with a brush this time (sprayed the patio too the first time!), has pretty much covered it and we like the new colour. Possibly could do with a third coat as it was so dark underneath but we're too exhausted. So pretty happy with the product and the very helpful staff and good service.

A better choice than varnish by DIY Granny

The product is easy to apply and two coats give a slight sheen to untreated wood. Got it to match skirting boards and dado rail to a dark oak floor. The match is good and believable. This was using the dark oak colour oil.
