Osmo UV Protection Oil Extra is ideal for use on all exterior timber, including external doors, window frames, windowsills, carports, timber cladding, balcony, screens & smooth fences, pergolas, summer houses and furniture.

Please Note: This product is not recommend for use on flat, horizontal surfaces where water can collect, such as floors, decking and wooden steps.

Osmo UV Protection Oil Extra (Natural 429) has been specifically designed to retain the natural, untreated appearance of lighter timbers such as Oak, Pine and Larch. It is not suitable for dark exotic hardwoods, as it may leave a 'milky' or 'white film' appearance to the wood.

The clear version of this product (Clear 420 Extra) can be used as a top coat for Osmo exterior coloured finishes, such as Osmo One Coat Only HS Plus, Osmo Natural Oil Woodstain and Osmo Country Colour.

Before opening the 5ml sample sachets, squeeze the packet several times to ensure that the oil and pigments inside are thoroughly mixed.

Ensure that wood surfaces to be treated with Osmo UV Protection Oil Extra are clean, dry and frost-free (moisture content max. 20%).

New Wood

  1. Surfaces should be sanded with a 120 grit abrasive and no finer
  2. New wood and especially hardwoods should be allowed to weather for approximately 6 weeks prior to oiling
  3. De-grease surfaces with methylated spirit or Osmo Brush Cleaner and Thinner (8000) before oiling
  4. Fill any holes or gaps with Osmo Exterior Gap Sealer
  5. Treat the wood with Osmo WR Base Coat (4001) or another exterior wood preservative for additional protection if desired

Please Note: Allowing the wood to weather, especially dense exotic hardwoods, enables the tight, dense grain of the timber to open up. This makes it easier to apply the oil and allows it to penetrate deeper in to the wood grain.

Old Wood

  1. Clean old microporous finishes (wood oils) thoroughly
  2. Areas affected by mould, algae and moss must be cleaned and treated
  3. Old paints, lacquers and varnish like stains must be completely removed
  4. The colour of timber that has turned grey / silver over time can be restored prior to oiling with Osmo Wood Reviver Gel (6609)
  5. Then treat as New Wood

Always do a test area before starting any project to check suitability and compatibility. Follow the manufacturer's instructions on the tin at all times.

  1. Stir thoroughly before and periodically during application
  2. Where possible treat all sides of the timber prior to installation
  3. Apply protection oil thinly along the wood grain with a natural bristle brush
  4. Work the oil into the surface of the wood grain
  5. Wipe of any excess with a clean, lint-free cloth
  6. Allow to fully dry
  7. Apply a second coat as above

Regular Cleaning

Oiled surfaces can be regularly cleaned with Osmo Exterior Spray Cleaner (8027).

Renovation

When renovation is required, ensure that surfaces are clean and dry.

  1. Lightly sand or use a stiff brush to remove surface dirt and debris
  2. Apply a thin maintenance coat of Osmo UV Protection Oil Extra, taking care to work the oil in to the surface of the wood and wiping off any excess
  3. For wood that has become discoloured or is showing signs of mould, algae or moss, refer to the preparation and application sections above

Q. I work for a joinery that makes and fits bespoke hardwood windows, doors and decking. Can Osmo UV Protection Oil be used on dense exotic hardwoods like Teak, Iroko, Ipe, Meranti and Garapa?

A. On the tin it states that Osmo UV Protection Oil Extra is not suitable for use on Iroko, Teak and other exotic hardwood timbers. This said however, we have customers that have used Osmo UV Oil with success on these woods.

Wiping the timber down with methylated spirit prior to applying the oil can aid penetration with these wood types. Other things that can help include allowing the wood to weather for 6 weeks and ensuring that the oil is at a good room temperature which keeps it thinner. Cold temperatures thicken the oil making application more difficult.

Q. Can Osmo UV Protection Oil 420 Clear be used on garden decking?

A. Osmo says that this product is not suitable for use on horizontal surfaces such as decking. This said however, we have customers that have applied one coat of Osmo Decking Oil then applied 2 very thin coats of Osmo 420 clear on top and have been happy with the results.

As with the Polyx Oil, the wood looks beautiful, but the coverage was not as much as indicated on the website, so we need another tin.

Can not say enough It is simply does the job by Pisti

Have used Osmo treatments many times and found it simply the best affordable product on the market. Obviously there are many great industrial oils on the market but there are down points of them. Down points of those: -Expensive -Large tin 5+L, when you do not need that much why... -Sometimes harder to apply industrial treatment than Osmo I well recommend Osmo over industriual treatments as it does offer the same qualities for less cost. About wood-finishes-direct: They are very fast about dispatch the item and always deliver on time, what they have in stock on the site they actually have it in stock. Well recommended store. Thank you again for the service..

Goes on smoothly to give fine natural finish by CHRISTOPHER SPARKS

Although not recommended I used on south facing mahogany door cill (after a few weeks of weathering). Dries slowly so needed to rub down cill and repeat application several times due to windy weather conditions causing dust to stick to it before drying. However used fine grit pad and wiped off with meths and got very smooth satin finish in the end. Too early to comment on longevity but repelling water nicely so far.

Brilliant colour for older Larch by Monzar Najami

Five years ago I have put up a new first floor on our bungalow made from timber frame and exterior Larch cladding. I have used OSMO 420 initially for preservation and longivity. I have refresshed it two years ago. However, as ever, the sides of the Larch started to show a bit of silvering, so I used a mixture of red cedar 428 and clear 420 ( 50/50) to restore the Larch, and it now looks super. Used also the OSMO wood reviver Gel at difficult locations, that was tiring to use and had to apply twice, sometimes no great success- but with t hered cedar tint it did the trick. Will have a major repaint job this summer and will buy this product

First class product by MR P J WALKER

Before my first purchase of this product from this company about three years ago I had used alternative treatment and suppliers which gave very inferior results. Having done some research I came across this treatment from Wood Finishes Direct. It has proven very good indeed, the best treatment for horizontal oak beams exposed to all elements. Although quite expensive it is worth the extra for the result is superb.
