Description

Osmo UV-Protection-Oil is ideal for all vertical wood surfaces in outdoor areas: doors, windows, window shutters (dimensionally stable elements), carports, timber cladding, balconies, fences, pergolas, and summer houses (dimensionally unstable elements). 420 Extra is also suitable for bamboo poles (e.g. in screens).

  • Clear UV Protection Oil 410 is safe for humans, plants and animals when dry
  • Clear UV Protection Oil 420 ExtraSamples available - is furnished with active ingredients to protect the coating against mould, algae and fungal attack

A clear, satin wood finish based on natural oil for wood in outdoor areas. Microporous surface allows the wood to breathe and reduces swelling and shrinkage. Water-repellent, will not crack, peel or flake.

As top coat on already colour treated wood, Osmo UV-Protection Oil prolongs the renovation intervals significantly. As a single product application, it blocks the greying process on vertical surfaces with a UV protection factor 12 in comparison to untreated wood when two coats are applied.

Osmo UV-Protection-Oil is furnished with active ingredients to protect the coating against mould, algae and fungal attack. Simply apply without sanding. Easy and seamless application. Finish stays workable while coating.

Finishes & Examples




Suitable & Recommended Wood Species


Recommended:

For all other wood types not specified, always trial apply.

  • Oak
  • Beech
  • Ash
  • Alder
  • Birch
  • Thermowood and Thermally Modified Timber (TMT): prone to grey very fast and therefore application of a tint/colour is recommended within the first two weeks after processing. Always trial apply the tint/colour to reach a harmonious colour tone with Thermowood / TMT.

 

Also Recommended:

For the following wood types, WR Base Coat is recommended before use.

  • Accoya
  • Kebony
  • Pine
  • Spruce
  • Douglas Fir

 

Recommended After Weathering Period:

For the following ingredient rich wood species, a weathering period is recommended to improve absorbency. New or freshly sanded ingredient rich wood requires at least 12 weeks exposure to the exterior elements (unless otherwise stated below) before application.

After the weathering period, it’s generally recommended to de-grey the bare surface with Osmo Wood Reviver Power-Gel, damp rinse, then clean the surface from the extractive content before application, always trial apply!

For all other ingredient-rich hardwood species not mentioned, please contact us for further information.

  • Cedar
  • Iroko
  • Mahogany
  • Teak
  • Walnut
  • Ipe
  • Merbau
  • Wenge
  • Rosewood
  • Sycamore
  • Pressure-Impregnated Pine
  • Sapele: 3-4 weeks exposure
  • Larch: 2-6 weeks exposure. Application of WR Base Coat is recommended before use.

 

Not Recommended:

The wood species below are not recommended.

  • Green Oak: moisture content is often above the maximum 20% recommended.
  • Idigbo: contains yellow dyes which leaches when the wood becomes wet and stains when in contact within iron.
  • Other woods treated with a varnish, lacquer or other surface coatings must be completely sanded before use.



Notes & Tips


  • Stir well using a flat stirring stick or spatula.
  • Sand wood to a final P120 grit sand-paper grade. This is the optimal grade for applying Osmo UV Protection-Oils.
  • For ingredient-rich wood species (eg: Cedar, Iroko, Teak, Mahogany etc.), please allow 12 weeks weathering prior to application.
  • UV-Protection Oils perform optimally on vertically structured timber. For horizontal sections there will be more maintenance.
  • On horizontal sections, ensure at least a 15 degree angle to facilitate water run-off. Sharp edges must be rounded (radius > 2 mm).
  • Over application, lower temperatures and poor ventilation will increase the drying times.
  • UV rays from the sun help to break down protective lignin surrounding the fibres in the wood. Moisture also helps to deplete the lignin and the wood fibres begin to grey naturally. Osmo UV-Protection Oils delay the greying effect 12 x more effectively than bare timber.
  • Osmo UV-Protection-Oil 420 is furnished with active biocides to help protect the film coating against the effects from mould, algae and fungal attack. The added biocides do not prevent mould, algae and fungal growth forming on the coating.
  • If a clear UV protective finish without biocides is desired ( eg for animal enclosures ), use Osmo UV-Protection-Oil 410.
  • Some timbers like Oak and Chestnut are notoriously rich in natural tannins and these ingredients can blacken surfaces when exposed to moisture, sunlight and iron oxides (eg from wire wool). Horizontal sections are more prone to discolouration whereby moisture can accumulate then escape through a breathable coating like Osmo. As the moisture escapes it lowers the risk of warping however, natural tannins can migrate to the surface and cause some black staining. To help reduce this, try to clean the first signs of tannin spots away from the coating with a damp cloth. Over time, the tannins will deplete and the discolouration will be less problematic. Choosing a darker coloured Osmo UV-Protection oil tint, or Osmo Natural Oil Wood Stain (excluding 701 clear matt) can also help to mask discolouration.
  • Many wood species (eg Larch) contain water-soluble colouredctives which may leach out naturally when weathered. Bare weathered wood can often be refreshed using Osmo Wood Reviver Power Gel prior to treatment. Always trial apply first.

questions Chris on 2024-06-13 18:50:00
Question: 

You say osmo oil is suitable for VERTICAL surfaces. What about HORIZONTAL surfaces eg sills?

Answer from Rawlins’ Technical Team:

Assuming the sills are external, are clean, dry, sound and prepared as detailed in the technical datasheet, Osmo Natural Oil Woodstain in 701 Clear Matt could be an option to horizontal surfaces such as sills, to allow the natural wood grain to remain visible whilst also being UV and weather resistant.

If the timber is oak or softwood, we'd recommend a first coat of Osmo WR Base Coat, assuming there are no previous preservatives soaked into the timber, prior to application.

Question: 

Your Datasheet talks about vertical surfaces, is it suitable for a Teak table top that is exposed to sunlight.?
