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 420 (Extra) 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.

Should you wish to opt for a non standard shade, please supply the specific shade reference number using this RAL chart.

Please Note: Colours chosen from any RAL number are Non-refundable.

Provide colour details in "Special Instructions" at checkout, allowing a minimum of 3 working days. Note: Osmo 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 or Osmo UV Protection Oil Extra Natural 429.

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 Extra Natural 429 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

Excellent high quality finish and a lovely colour by Craig Rose

I wanted to try to change my shed colour from a very dark brown and had previously not been able to do it with other products. I used a sample of basalt grey and liked the colour. I then applied 3 coats thinly. The result is a lovely green/grey sea colour which I really like. The finish also feels like it will fully waterproof the shed. My neighbour said he thought it was new. I also like the fact Osmo uses renewable oils .I will definitely be using their products on my external wood in future.

Easy to apply. Gives good Matt finish & only darkens the wood a little. Used on our new bespoke sapele doors. No knowledge as to long term effects...too early to tell.

Goes on well, great colour, and looks like it's really going to protect the wood; by Richard Bishop

I needed something to protect a wooden bench in the greenhouse, and this seems perfect; 3 coats and it looks as if it will last forever.

Beautiful colour Excellent result by Martin Price

I used this for a side gate that I built from scratch. The end result is amazing - the gate looks really smart and water just beads off it. The method of application appeals to my Yorkshire instincts - although the product is not cheap, you apply really thinly in each coat so it goes a long way. It looks good at each coat and as there is a good level of pigment, you can see where you have applied for each coat.

Looks good but time will tell by P Thomson

Easy to apply and finish is good, but didn't cover as much area as I expected (about 20% less) but different wood adsorb different amounts.

Product high quality and easy to use by Sarah Brown

Purchased basalt grey oil woodstain for outside my log cabin summerhouse, and white oil tint for Inside. Feel this is money well spent. Both provide a translucent matt/silk stain effect with one coat and a heavier protective silk finish with 2 coats. This is a cover which is clearly not paint and does not look like it will wear or flake with time which is why I chose it. I wanted a durable finish to update rather than one I would need to take back to the wood. The woodgrain can be easily seen especially using the indoor oil. Used over a clear wood preserver for extra life which worked well. Coverage was exactly what it said on the tin.

Too small sample by Charlie Webster

A note from us...

Hello Charlie,

The Sachets cover about 8- 10cm squares, if you would like a larger area covered then you could look at the small 125ml tins which will cover one quater to a half meter squared. Please let me know if there is anything I can help with.

Kind Regards Sam.

Great quality and easy to apply . Make sure you really stir well as I thought I had , but the last bit was very dark. And hard to apply .

Very easy to apply , no drips, excellent finish by Sheelagh Handford

Initially I bought three samples to paint my wooden gates in the colours Basalt,Pantina & Pearl. Basalt had a slight khaki tinge and Patina was a dark grey. Pearl was the lightest and tones in well with my sandstone walls. It was easy to apply but I did need three coats to get a uniform application as some of the slats absorbed the oil more than others. Since using the product the rain has beaded on the surface and not been absorbed by the wood. The gate is hung under a tree so I do have moss/algae problem and I will be interested to see how the oil is over time.
