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.
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.
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.
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
Used this product before for my dinning room table. Easy to use and leaves a factory finish
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.
Liked it better than sadolin ,even colouring if stirred now and then,two coats on a new 7x9ft shed well protected from the Scottish elements,does what says on the tin,,,,,wasn't cheap,got what I paid for ok.would recommend it in all honesty.
Early dats bit Looks excellent. Recommend applying with the micro cloth. A little really does go a long way
Good coverage, really smartened up our summerhouse, first time using but would definitely recommend.
Not as thick as I hoped but worked real well and looks good. Had to give it several coats and ended up with some smudging near the edges but really like the overall effect.
Easy to apply and gave good coverage.
Great for what I needed. I stained the sign I was making and it proved to be a great background for the paint I was applying.
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 use with great results!
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.
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.
Great and easy to apply with pad
A lovely grey wood stain used on an old pine dining table gave it a real modern look.
... just got to make sure to apply thinly to avoid streaks
I had already used this product so it was exactly as I was expecting. As to how long it lasts.... will have to wait and see.
Beautiful render. Easy to apply. Keeps the natural texture of the wood even after second coat
Osmo products have yet to let me down.
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.
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.
