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. Osmo do not recommend that this product is used on flat horizontal surfaces where water can collect such as floors, decking and wooden steps.
Please Note: 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 Oil are clean, dry and frost-free (moisture content max. 20%).
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.
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.
When renovation is required, ensure that surfaces are clean and dry.
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.
Easy to apply and effective - so far
Used it before, bit expensive but is a quality product, used it on my summerhouse
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
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.
Use on top of Country colour to help with mould control on our coastal property. Helps a lot.
Have used Osmo in the past, delighted with it then, as I am now with the latest batch. The finish and protection is almost beyond belief. An amzingly good product - gives lasting protection and looks. Well worth the expense.
takes a while to dry but good finish
Used on shingles long overdue for treatment. Excellent result. The house is greatly admired by all who pass - thanks to Osmo and our conscientious tradesman. Will certainly use it again in the future.
Goes on well but like it says on the tin better to be dry or warm.
Used as a follow on to Osmo wood reviver, which left the wood quite pale. But this made it look like oak again.
This product does exactly what it says on the tin
Professional and well informed customer service led to our purchasing the ideal product to revive our oak porch. - delighted with the outcome and would definitely recommend Wood Finishes Direct and their Senior Sales Advisor Alison Oakes.
Does a great job reviving our pavilion. Am very pleased with the result.
The longevity of the effects of the oil on outside wood is outstanding and even after 3 years of weathering, the wood looks it was put on yesterday
Wood finishes were extremely helpful and informative. The product seems very good although I have only prepared samples so far. I had to pay for the sample which I think should be free with orders of other Osmo products over a certain amount or at least redeemable of a later purchase of the colour you want.
Easy to apply, stops oak going grey.
excellent product when applied to prepared surfaces
No need.... just does as it says on the can!
I had used Osmo clear in the past on an exterior oak frame which was good. The 425 Oak does not appear to have that much colour in it, but it did raise the tone the finished article and it looks a little smarter than with the clear.
