After recently using Osmo UV-Protection-oil recently, I thought I would write a review on the product. I will admit to being slightly biased towards Osmo as I am already completely sold on their other Anti-Slip Decking Oil. In fact, their whole range is spot on in my opinion.

- Approx. coverage: 18m²/L with one coat
- No. of coats: 2
- Application temperature: +5°C to 35°C
- Drying time: 12hrs.
- Sizes: 0.125L, 0.750L, 2.5L
Osmo UV-Protection oil covers around 15-16m²/L with one coat, which isn’t as much I’d like from a product; however, this was from the wood already being silvered.
My Osmo UV-Protection Oil Review
Two coats and the timber looked amazing!! In fact, it looked pretty good after one coat!! You need to work the Osmo UV protection oil into the timber on your first coat. The product penetrates the timber and brings out the grain. A quick sand off with some light sand, dust down, then you’re free to apply your second coat which is a dream to apply. You’re left with a rich finish like nothing I’ve ever seen!
The drying time is around 18- 24 hours. This is an inconvenience as the tin states that the optimum temperature is +5°C to 35°C, which in the British Isles is not always possible.
The oil transforms silvered Oak almost instantly, giving it a stunning colour and bringing the grain out as we all know a decent oil should.
The consistency is also really nice. It was quite viscous, making it flow easily off the brush. I did notice it went a lot further on the second coat.
One of the key benefits of this product is that when once it has being used, it doesn’t need sanding prior to future applications. this is because it is microporous. This means it protects the timber from the whether, but doesn’t trap moisture in the wood. Osmo UV protection oil will also cope well with timber expanding and contracting with the weather.
The advantages of Osmo UV-Protection Oil are as follows;
- Very water and dirt resistant
- Reduces wood swelling and shrinkage
- 410 Clear is safe for humans, plants and animals once dry
- 420 Clear contains biocides to resist the growth of algae, mildew and fungal attack
- Microporous, breathable finish – does not crack, peel, flake or blister
- No sanding necessary for future applications

Three Years After Using Osmo UV Protection Oil
It is now a couple of years after I originally published this review. I thought I’d come back and add to it, having learnt a little bit more about Osmo UV protection oil. It turns out it doesn’t last as long as some of the other timber care products which are available. Ideally you should apply at least one “top-up coat” every year. This is ok as long as you bare this in mind and stay on top of your external maintenance. You may be better with Fiddes HD oil on your project.
Another downside of Osmo UV Protection oil is you can’t apply it over the top of a previously sealed surface. You can apply it to bare timber, or over the top of itself. What you can’t do is apply osmo oil over the top of stain or varnish.
Best Tools to Apply Osmo UV Oil
I thought I’d include a little section on the best tools to use when applying this type of material. Osmo recommends their own Flat Brush, which is cheap and will do the job. But for me, the best brush for Osmo UV Oil is the Kana Tank.
The Kana Tank brush comprises of an inner core made from natural fibre bristles, which are then encased in synthetic bristles. The natural bristles hold onto thin material like Osmo Oil, and the synthetic ones help you manipulate it into the timber. Using this paintbrush will help make your life easier when applying the oil.

You will also need a clean paint kettle, some fine grade sandpaper or wire wool, and a tact cloth to pick up any dust.
I hope that helps.
