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.

  • Overview

Overview

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.

Preparation

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.

Application

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.

Repair

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

Cleaning of equipment

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

Storage

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.

Caution

  • 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

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.

Finishing

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. This is not recommended for the white Osmo Natural Oil Woodstain finish (product code 900) as the UV protection oil can make the white look creamy or an off white.

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

Expensive but high quality
An expensive, quality product that goes a long way. Easy to apply, although quite thin so beware of drips. I am using it on new gates and old windows and both take it very well. It seems to sit OK on top of previous stains etc that I can't get off on the windows and two coats gives a good satiny finish. So far it is working well.

Exactly what I wanted
I wanted a translucent white for a pine wood table and this was perfect. You need to really spread the colour thinly to achieve a translucent look where you can still see the grain, but even if you spread it a bit more thickly it still looks good.

I have used this product for many years, it covers well, is easy to apply and lasts well
Although not initially the cheapest wood protection product on the market, its finish endures well and on the wooden buildings in my garden it will continue to be used.

 2.5L, Oak - 706
Worth the extra £
I have treated two buildings clad in pine. Some wood I used the roller, also purchased from Wood Finishes, this produced a darker stain. I prefer the result of the oil rubbed in with a cloth - it really shows the grain. I did order 3 samples before settling on this oak colour.

Great coverage
Good coverage over old decking, used a pressure washer first and although there was a few colour differences the Osmo has covered well.

 750ml, Red Cedar - 728
Very good!
Easy to apply, had 2.5 ltr container that lasted for more than 150 linear meters of siding boards, gives Red Cedar a wonderful colour, retains the natural patterns of the wood and penetrates pretty well into the wood, I am very impressed with this product!! Protecting from sun over time!!

Good coverage, dried quickly.
Good coverage, dried quickly enough not to be marked by light rain shower arriving unexpectedly. Colour a bit muddy, not quite as red as I'd hoped.

Good quality finish but needs clear instruction of how to achieve best finish results
Good quality finish but needs clear instruction of how to achieve best finish results. Top tip! Apply thinly with a microfibre roller and then pull the finish with a flat paint pad. Works a treat.

What a fabulous finish
After treating our garden bench with the barrentine wood preservative we proceeded to give it a coat of the Osmo oil treatment,what a fab finish and protection that should last a lot longer than what we have used every year previously.

Good colour and coverage
Despite its rather high cost, the initial impression of Osmo natural oil wood stain is very good colour, ease of application and excellent coverage. Only time will tell concerning its long lasting preservative qualities.

 2.5L, Basalt Grey - 903
This is a great product to look after your shed
Do not load your brush heavily to avoid drips. Two coats provides a great finish with the grain showing. I love this light grey. It lightens up after a few days. Not a cheap product but worth every penny.

 125ml Sample, Basalt Grey - 903
Good quality oil paint
Yellowness of the wood mixed with some colour pigment from the paint turned some parts slightly green but will get a better and complete coverage with 2nd coat. Needed quite a but more then the calculator stated, I was painting external clad and think the calc is based on plained finished

 750ml, Ebony - 712
Excellent. Great product. Easy to apply and looks good. Wood is well protected now.
The member of staff at Wood Finishes was very good. I've used Osmo interior products before and they are simply the best on the market, so this exterior stain should last for years.

Does what it says on the tin.
Nice, quality product. But, to my mind, it goes on a bit too thin: you have to brush it out very thin to stop it running, and then I don't think the recommended two coats look like enough; I think I'll have to put a third coat on, both for appearance and weather protection.

Good product/easy to apply but expensive in first instance.
Easy to apply and went much further than I anticipated which was a bonus as the stain is expensive compared with other wood protection products on the market. Hopefully it will last longer
