Product Description

Osmo Natural Oil Woodstain Effects are a range of woodstains in four attractive silver-metallic tones, satin-matt oil-based protective finish suitable for exterior wood. Microporous, breathable finish allowing the wood to breath and reduces the risk of swelling and shrinkage. Water-repellent, extremely weather and UV resistant. The finish contains active ingredients which protect it from mould, algae and fungal attack.

The finish is proven over decades in all kinds of climatic conditions, and does not crack, flake, peel or blister.

Easy to renew, no sanding or primer necessary.

Easy to apply, does not dry during application.


1 litre will cover approx 26m2 on smooth timber and approx 12m2 on rough sawn wood. The coverage on absorbant timbers can be significantly improved by coating with 4005 WR Base Coat first. Please note that grooved decking will require approximately 30% more than smooth decking.

Recommended use

All exterior woods (dimensionally stable and non dimensionally stable): doors, windows and windowsill, carports, timber cladding, balcony, wooden decking, screens & fences, pergolas, garden houses and furniture. Please note that only a single coat should be applied and then the product must be overcoated with anti slip decking oil for areas with foot traffic such as decking.

On vertical surfaces the life of the product can be greatly extended by applying a top coat of Osmo UV Protection Oil 420 Extra when the woodstain is completely dry.

*Please note that the colour shades displayed are a true likeness of the original however different output methods (screens & printers) will cause variation in colour. In addition the colour will vary with the wood depending on age, pre-treatment etc and therefore it is always advisable to test on a small inconspicuous area first.
