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.

  • 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.
  • Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment. Do not empty into drains, dispose of this material and its container at hazardous or special waste collection point.
  • If swallowed, seek medical advice immediately and show the tin 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).

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.

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

I've used Osmo for many projects Its great by Chris Chamberlain

Osmo is one of the best oil based finishes I have used.

Excellent wood finish by Nigel Watkins

As recommended a preservative undercoat allowed the oil to soak in and protect the wood on a very exposed balcony and the finish literally throws off any rain water.

Fabulous product at a reasonable cost by Mrs Charlotte Seymour-Li

I am using two products as for inside and out. Both arrived well packaged and in good time. I needed help from the tech team as to what was best and got it in spades. They were brilliant and knowledge and the final product have made the project easy to do and looks fantastic. Will buy again if I need more!

Excellent service - Excellent Product by GJ Smith

Delighted with my new driveway gates and adjacent entrance fencing I did not want the weather and sun to later degrade the natural appearance. Fortunately I found the Wood Finishes Direct website and this UV protection product that I was previously unaware of. Application was simplicity itself and the final result has drawn much praise from others. I had never heard of Osmo before but a number of my neighbours have remarked how they have used Osmo before and how remarkable their products are.

Used this on my new 12x8 shed. Very good coverage and have enough left to apply another coat in a couple of years time. Darkens the wood slightly but not a problem for me.

I love the finish and the fact that it doesn't crack or peel Also it is simple to touch up by John Orsi

I used Osmo oil firstly on a new internal staircase and the results were stunning. My carpenter was immensely impressed. When I had a new mahogany balcony fitted, I looked for an external version of the oil and again the results were excellent. It is easy to use and to touch up.

Tough finish by Julia

Necessary to provide a durable top coat with a pleasant mid sheen. Apply sparingly with a fine bristle brush. Although stated as clear the top coat oils or varnishes always seem to darken the wood a shade and can leave pale woods looking yellow and 'pine-y' rather than cream and light. I managed to offset this effect by applying osmo polyx oil white tint sparingly as the first coat. Am currently considering a further treatment using a buffing wax for a smoother sheen to finish the doors off.
