Review: excellent product - This stuff, although expensive, gives a really good finish on wood. I used 2½ tins of 2.5 litres to give 2 coats outside and 1 coat inside on a 4m x 3m log cabin. The Osmo I ordered was the clear, so no colour stain was in it, and it gave my natural white wood finish a pale yellow/golden hue. The finished effect was very slightly glossy after 2 coats. I also used it on some garden furniture, and it worked just as well on treated and stained Larch. I finally used it on some small pine tables.. I gave then 4 coats, and finished with a really superb glossy transparent finish, better than most varnishes. The Osmo was really easy to apply, my only problem was that in some lights, I couldn't see where I'd applied the last brushful, so had to go over again to make sure I'd covered the lot. I also bought the Osmo natural bristle brush, and it was also great. I think in all the applications, I only lost 2 bristles, and the brush was just the right size (50mm) for easy use. I did also buy some of Osmo's Brush cleaner and thinner. This stuff cost £13.75, but I found that for just brush cleaning, ordinary white spirit did the job just as well, so I wouldn't buy it just for cleaning.
Review: Great service - Great product, service and value thank you

## Questions & Answers

**Q: After treating the door with this can it be painted over ? Or paint before and finish with this product ?**
A: I'm not sure why you would want to paint over this product.
The clear oil is to enhance the wood grains in the door.
You would need to sand the door back to the wood and apply a primer in order to paint the door.

**Q: I've heard people say you have to use a wood preserver first...Is that right?**
A: No you do not need to use a wood preserver first. In areas of high humidity or to improve coverage on dry or rough sawn wood you can use Osmo 4005 WR Base Coat.

**Q: What's the difference between osmo 420 extra uv protect exterior and satin/matt? i want to use it for garden furniture.**
A: Hi the UV Oil 420 is the best product to use - its a satin finish. Osmo called it satin-matt but they have since changed the labels to just satin.

**Q: My fence panels were pressure treated in the factory. Is there any advantage for me in getting 420 over 410 in this case?**
A: I have used the 410 on pre-treated timbers that were sanded down and then 2 coats of 410 applied. This has been very successful so unless you live in an area with harsh weather conditions or near the coast I would say 410 is perfectly adequate. The manufacturers recommendations should prevail though.

### ⭐⭐⭐⭐⭐ Great service

Great product, service and value thank you

### ⭐⭐⭐⭐⭐ Excellent protection for external wood
*by R***B on 1 March 2021*

This is professional grade protection for external wood where you want the grain and appearance of the wood to be preserved and enhanced as well as the wood itself given protection. Once applied the grain of the wood shines though and the whole surface has a lustrous, 'cared for' appearance. Rain simply runs off. Disadvantages are that it needs care to apply. It is pungent; nicely so but still best to use in a ventilated area. The wood surce should be carefully prepared and it is best applied to freshly sanded surfaces. It is an oil so it does run and drip and it can be very slow to dry in all but the warmest weather. Stonkingly expensive but worth the price if you want the best treatment for well-prepared wood surfaces.
