  • Overview


Osmo UV-Protection-Oil 410 offers a satin-matt, clear finish for exterior wood. It is based on natural oils and does not crack, flake, peel or blister. Osmo UV-Protection-Oil 410 prolongs the renovation time significantly with a UV-Protection factor of 12 in comparison to untreated wood. Easy to apply and renew, no sanding or primer necessary.


Wooden surfaces must be clean, dry and frost-free (maximum moisture content 20%). Osmo UV-Protection-Oil is ready to use straight from the tin and doesn't require thinning. Stir well before use.

Clean existing oil finishes thoroughly. Any previous traces of varnish must be removed completely. Surfaces should not be sanded finer than 120 grit.

If additional protection against blue stain, rot and mildew is required for outdoors pre-treat with Osmo WR Base Coat 4005.

Please Note: Osmo WR Base Coat 4005 does not contain an insecticide so will not protect the wood from wood worm or other wood boring insects. For complete protection against mould, algae, dry rot, woodworm and other wood boring insects, consider Barrettine Premier Wood Preservative or Ronseal Total Wood Preservative. If using either of these products, please allow a full 24 to 48 hours drying time before applying Osmo UV Protection oil 410.

Wooden surfaces that have turned grey / silver over time can first be treated with Osmo Wood Reviver Gel 6609 to restore the colour of the wood prior to coating with Osmo UV Protection Oil 410 or wood preservative.


Apply thinly and evenly along the wood grain with either a good quality paint brush or Microfibre Roller, working the oil in to the surface of the wood. Allow for good ventilation whilst drying. Apply a second coat as before

Make sure that the surface is clean and dry prior to application. The finish is among other things influenced by the wood's natural characteristics, therefore a trial application is required before finishing.


Depending on the level of weathering apply 1 to 2 coats of Osmo UV Protection Oil 410 approximately every 2 to 3 years on cleaned and intact wooden surfaces.

A shorter renovation period may be required if wooden surfaces are exposed to extreme weathering. This may also apply to horizontal surfaces where water cannot drain.


If the surface becomes scuffed, scratched or marked, simply rub the effected area with a scotch pad then re-apply a coating of the 410 exterior wood oil to the damaged area.


To clean brushes use Osmo Brush Cleaner and Thinner 8000. To remove excess oil or spillages use white spirit.


Shelf-life is up to 5 years or more if product is correctly stored. If thickened by frost, it will regain its consistency under normal temperatures within 24 to 36 hours.

To maximise the life of any left-over oil, decant into a container bottle or jar with an air-tight lid. Fill the container to the rim minimising the amount of air in the container and secure the lid. Store in a location where the product is unlikely to freeze or overheat such as an under-stairs cupboard.

Q. It states in the Osmo leaflet that this product is for exterior use. Can it be used on the interior of a real wood conservatory as it gets full sun for much of the day and i would like to protect the colour of the timber.

A. Osmo UV protection Oil 410 is classed by Osmo as an exterior product. This said however, we receive lots of positive feedback from customers who have used Osmo 410 on interior wooden surfaces such as window frames, sills and wooden conservatories.

Q. Can Osmo UV protection Oil 410 be used on conservatory or kitchen floors that are subjected to direct sunlight?.

A. The product advice from Osmo is that this product is not suitable for use on horizontal surfaces such as floors as it doesn't have the same durability as their interior Polyx Oil products. This said however, we are aware that some customers have used Osmo 410 on flooring then applied a coat of Polyx Oil over the top for added durability.

Drying Time

approximately 12 hours (normal climatic conditions, 23℃ /50%, normal humidity). Lower temperatures and/or high humidity can increase the drying time.

Really good
Easy to apply and dried quickly despite the cold spring weather.
Mark Robertson
Perfect, simple and easy to use product and customer service
I'm a DIYer and needed some advice on products. With one easy phone call I was sorted and order placed. Delivery was planned and on time, with no fuss or issues. (3 deliveries in total over a couple of weeks) the tester pots were ideal to make sure I got the colour I needed, and the finish was professional standard. Great.
Sean Hogg
Easy to use and goes a long way
Used this product on some oak doors that were in a bad way, after a good sanding and 2 coats of osmo uv protection oil you would not believe they were the same doors. They look great, infact someone asked me if they were new! Can't say how good the product is over years but my initial impression of this oil is that it is superb.
Lawrence Smith
Exceptional product
Does what it says and eco too.
Christine Chinn
Excellent oil well worth the money
I use this product more than any other exterior wood finish. Always goes a long way and leaves timber looking natural, whilst offering a high degree of protection from the elements.

I recently purchased a bird table and loved the colour of the wood. I didn't want it to go grey as so many people do, but I wanted that rich cinnamon colour to remain. The joiner told me about OSMO products and suggested the UV Protection oil. I bought it the same day and applied it the following day. The initial coat made the colour even more vibrant which I was very pleased about. Two days later, it began to rain, but the bird table repelled the water and remained looking good. I would highly recommend the OSMO UV Protection Oil to anyone wanting to preserve their outdoor wooden products. It's great!
David Perkins
Perfect finnish
This product transformed my old oak front door. Looks great.
Frank Mansell
The need to clean off any old varnish down to bare wood is essential. After this treatment of grey spots on the oak with diluted bleach was prudent before treating with Osmo reviver gel. The Oil then brought out the grain of the wood after treating it with Osmo reviver gel. Easy to apply and gives a rich finish. The proof of its usefulness will be after exposure to the winters we get here in Wales so watch this space!
Jeff Westwood

Product was fantastic.
I used it on my oak front door. It's the only product I have tried that has not turned wood yellow or orange.
