Description

Osmo UV-Protection-Oil Tints 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). Also suitable for bamboo poles (e.g. in screens). Samples available.

Transparent, lightly pigmented and satin, natural oil based wood finish for exterior use. 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 Tints 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 Tints 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: UV-Protection Oil Tints 425 Oak (for a darker shade) and 429 Natural (for a lighter shade) are optically suitable.
  • 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.

  • Douglas Fir: UV-Protection Oil Tints 427 Douglas Fir is optically suitable.
  • Pine: UV-Protection Oil Tints 424 Spruce is optically suitable.
  • Spruce: UV-Protection Oil Tints 424 Spruce is optically suitable.
  • Accoya
  • Kebony

 

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: UV-Protection Oil Tints 428 Cedar is optically suitable.
  • Iroko
  • Mahogany
  • Teak
  • Walnut
  • Ipe
  • Merbau
  • Wenge
  • Rosewood
  • Sycamore
  • Sapele: 3-4 weeks exposure
  • Larch: 2 weeks exposure. Application of WR Base Coat is recommended before use. Then, UV-Protection Oil Tints 426 Larch is optically suitable.

 

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.
  • Flat surfaces: such as decking, window sills, garden tables, seats, benches and other joinery whereby rain is able to remain on the surface for long periods of time.
  • UV-Protection Oil Tints 429 Natural: not recommended for use on ingredient-rich (dark/reddish) wood species because it is visible as slightly white chalky surface. Remove white pigments from surface before leaving to dry. A trial application is always recommended.
  • 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. Failure to mix the colour and all ingredients could lead to an increased patchiness.
  • Ideally the new surface will be finished 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. Weathering will improve absorbency for the Osmo product to penetrate in to the wood. If the wood has greyed after weathering, use Osmo Wood Reviver Power Gel to refresh the colour once more. Avoid refreshing colour through sanding as this will reveal fresh wood ingredients, and the surface will need to be weathered once more.
  • Osmo UV Protection-Oil Tints 429 Natural is not recommended for use on ingredient-rich (dark/reddish) wood species because it is visible as slightly white chalky surface. A trial application is always recommended
  • Over application of Osmo UV Protection-Oil Tints 429 Natural may lead to the inherent white pigments becoming visible. Remove excess white before allowing the surface to dry.
  • 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 and/or low ventilation can 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 Tints are 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.
  • 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 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 can also help to mask discolouration.
  • Many wood species (eg Larch) contain water-soluble coloured extractives 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.
