Perfect for use on all exterior timber including external doors, window frames, windowsills, carports, timber cladding, balcony, screens & fences, pergolas, garden 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.
IMPORTANT: The Osmo 429 Extra has been specifically designed to retain the natural, untreated appearance of lighter timbers such as Oak, Pine, Larch, however it is not suitable for dark exotic hardwoods as it may result in a 'milky' finish or appearance.
Ensure surfaces to be oiled are clean, dry and free from all surface coatings such as paint or varnish before application. Wood that has been previously oiled should be cleaned and lightly sanded.
New unpreserved or old wood should first be treated with a quality wood preservative such as Barrettine Wood Preservative or Ronseal Total Wood Preservative before applying Osmo UV Protection Oil. Using a wood preserver prior to applying the oil gives additional protection against mould, algae, dry rot, woodworm and other wood boring insects. Allow sufficient time for the preservative to dry, normally 24 to 48 hours, before applying.
As an alternative to spirit-based preservatives Osmo WR Base Coat 4005 can be used. This product penetrates deeply into the wood to help repel water and moisture. This helps to reduce the risk of timber swelling and shrinking therefore reducing the chance of the wood cracking, splitting and warping.
Apply in thin coats with a paint brush or velour roller ensuring that the oil is worked into the grain of the wood as opposed to painted on top of the wood. Always finish your brush or roller strokes by going in the direction of the wood grain.
The Clear Osmo UV Protection Oil Extra 420 Extra can also be used for lightening or overcoating Osmo Natural Oil Wood Stain for added protection and durability.
Over Application of Natural - 429 Extra will result in a 'white wash' finish and in the worst cases white swirls, brush marks and a sticky or tacky surface. A test area and trial application should be undertaken before starting any project.
Slightly tired looking areas can be easily refreshed by simply cleaning the affected areas and applying a fresh coat of Osmo UV Oil. Even badly scratched areas can be seamlessly repaired with a light sanding and a re-application of the oil.
Application brushes and other equipment should be cleaned with Osmo Brush Cleaner or White Spirit.
Osmo UV Protection Oil Extra has a shelf life of 5 years or more if kept sealed in the original tin. Store in a dry cool place. If thickened by cool temperatures or frost, the oil will regain its normal consistency within 24 to 36 hours of being returned to normal temperatures.
To preserve any remaining oil once the tin has been opened and used, decant any remaining oil into a smaller tin, jar or container, fill to the rim and seal with an air tight lid.
Osmo does not recommend that this product is applied to flat horizontal surfaces where water can collect such as floors, decking and wooden steps etc.
Be aware that rough sawn timber is more absorbent, meaning coverage per litre will be greatly reduced.
Q. We have a garden table which says only use Roble Wax and not Linseed Oil. I have searched for this product and even with the Internet I have not succeeded. The table was from B&Q. Please can you help me?
A. To my knowledge, it's only B&Q that offers the Roble garden furniture in The UK and the product recommended for finishing it is indeed hard to find. We have looked into this thoroughly and can confirm that Osmo's UV Protection Oil is ideal for Roble wood. As Roble is a dense, oily wood it is important to work the oil into the wood well and apply it thinly.
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 but we have customers that have used Osmo UV Protection Oil with success on these woods.
Lightly sanding with a 120 grit sandpaper helps to open the tighter, less porous grain of exotic hardwoods enabling the oil to penetrate easier. Wiping the timber down with methylated spirit prior to applying Osmo UV Oil can help to remove some of the natural oil from the surface of the wood which helps the Osmo Oil to penetrate. Ensure the oil is at a good room temperature as it thickens when cooler making application more difficult. Apply thinly working the oil into the surface grain of the wood.
Q. Can Osmo UV Protection Oil 420 Clear be used on garden decking?
A. Osmo says that this product isn't 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.
Osmo UV Protection wood oil dries in approximately 12 hours in normal climatic conditions of 23℃ / 50% relative humidity. Lower temperatures and higher humidity can increase the drying time.
Good product but not what I needed for a staircase. Colour was virtually the same as the ceder. Good product but not what I needed. Thank goodness for the sample.
Tried this for my new stairs. Took a longtime to dry and was not the right product for high footfall areas so didn't bother. Colour was excellent very rich though there was no difference between the oak colour.
Excellent product would highly recommend.
Used on cedar cladding, Osmo 428 Cedar leaves a rich sheen that enhances the woods natural beauty and was easy to apply with a foam roller.
Leaves a nice silk finish, and goes on easily with a good paint brush. After heavy rain you can see the waterproof barrier. It is costly to buy but it is the best . .
Easy to apply and very pleased with the finish.
So good we order another tin to complete coverage of further wooden garden furniture
Leaves a lovely red finish. Just make sure it's applied very thinly to new wood otherwise it doesn't dry.
Easy to apply, absorbed well into shingles. Appearance once painted is very natural looking. Shingles retain their natural appearance. So far UV protection has been good, looking forward to seeing what happens in the longer term of course.
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!
It goes on well but takes a week or so to dry properly.
Very thin and easy to apply. Spread a long way!
Excellent product which I applied to my oak gates leaving them with a great finish.
This product does exactly what it says on the tin and covers the wood as it should
I know it's a brand strapline, but this product really does what it says on the tin, easy to apply too a rich finish.
Most people are unaware of how much better oils are for protecting wood. I have a piece of wood inside my shower because none of the rooms in my house are square so to fit the shower in the corner of my bathroom it was necessary to put this 2" x 4" piece in. I treated it with oil ten years ago and the wood is still perfect. Varnish would not tolerate ten years in a shower.
Mixed with 0.75 litre Cedar 428 Extra for red cedar outside room - good match with original wood.
Recently applied to cladding. 2 coats applied and about quater of a tin left. Very easy to apply. Seems to be very water repellant and the wood has ceased fading, which was my while reason for applying. Have also used on a shed door and frame and it seems to have coped equally well in these applications also. Not a budget option however from what I have seen and read this product really works as intended and will save you time and money in the long run.
Brilliant to top coat my new oak gate.
Easy to use, good coverage and protects well.
