The Osmo UV Protection Oil has been designed in order to combat the greying effects of the Sun's UV rays. Many woods like oak, teak and iroko to name just a few will become grey or silver over time and this oil will slow down that greying process by a factor of 12 when compared to natural wood. Normally the Sun's rays can penetrate through the clear coatings and bleach the wood below but this product contains special ingredients to combat this. The '420 Extra' contains Biocide which is a combination of insecticide and fungicide making it ideal for outside use.
This product is micro-porous, thus allowing the wood to breathe. Because the oil does not form a seal on the surface of the wood it cannot peel, flake, crack or blister. It is based on natural oils and offers a very clear, natural effect when compared to other 'clear' oils and penetrates into the wood grain aiding the natural elasticity of the wood and helping to reduce shrinkage and swelling.
Ensure surfaces are clean, dry and are free from any surface coating such as paint or varnish before application.
New unpreserved or old wood can 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 offers the best all round protection. Allow sufficient time for the preservative to dry before applying the oil.
Osmo WR Base Coat 4005 penetrates deeply into the wood to repel water and reduce the risk of swelling and shrinking but does not contain an insecticide.
Apply in THIN coats with paint brush or mohair roller. Always finish your brush or roller strokes by going in the direction of the wood grain. Osmo UV Protection Oil Extra 420 can also be applied over Osmo Natural Oil Woodstain as a top coat for added protection and durability.
Slightly tired looking areas can be easily refreshed by simply cleaning the affected areas and applying more of the oil. Even badly scratched areas can be seamlessly repaired with a light sanding and a re-application of the oil.
Osmo recommend that this product is NOT used on horizontal surfaces such as floors, decking and wooden steps etc.
On the tin it states that it is not suitable for use on Iroko and Teak timbers but customers have used it with success on these woods. Our advice is to ensure the oil is well pushed into the wood grain as it they are tighter and less porous woods. Sanding them a bit rougher (about 150 grit sandpaper also help).
Q. We have a garden table which says only use Roble Wax and not linsead oil. I have searched for this product and even with the Internet have not succeeded. The table was from B+Q. Please can you help me?
A. To my knowledge, it's only B&Q that offer 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.
