Wood surface must be clean, dry and frost-free (moisture content max. 20%). UV-Protection-Oil Tints is ready to use. Do not thin. Stir well using a flat stirring stick or spatula before use. Ideally, surfaces are sanded no finer than a P120 grit grade of sand paper. Sanding to finer grades will reduce required absorbency.
If possible, and if the wood is absorbent, please apply first coat to all sides before installation. Fresh wood containing natural wood ingredients /extractives (eg: Cedar, Teak, Mahogany or Iroko) are often less absorbent and need to weather off first before applying the product. Please refer to website ‘Suitability’ section for more details. Weathering helps ingredient rich wood become more absorbent and the wood finish adheres optimally.
For renovation works, clean old microporous stains thoroughly – if necessary sand lightly. Clean and restore already greyed or weathered wood at the same time with Osmo Wood Reviver Power-Gel. Old paints and lacquers must be completely removed. As a general rule, wear a dust mask during sanding works. To maintain absorbency, avoid sanding surfaces finer than a P120 grit. Weather ingredient rich wood after sanding.
The finished surface is influenced by several factors, including the condition of the wood. Therefore, a trial application is always required, especially for unfamiliar surfaces.
Soft wood species like Pine or Spruce are more prone to blue stain, rot and insects. If desired, pre-treat these soft woods if possible on all sides with Osmo WR Base Coat.
METHOD OF APPLICATION
With Osmo Flat Brush or Osmo Microfibre Roller, apply thinly along the wood grain and spread well.
Allow to dry for approx. 12 hours under good ventilation.
Then apply the second coat.
Alternatively the second coat can also be carried out with UV-Protection-Oil Extra Clear.
When recoating colour treated surfaces, or for renovation works, one coat applied to the clean and dry surface is usually sufficient.
Depending on the degree of weathering, apply one coat of Osmo UV-Protection-Oil Tints to the cleaned and intact finish after approx. 3-4 years.
For areas exposed to strong weathering, such as horizontals, weatherboard, post caps or window sills, please expect significantly shorter renovation intervals.
Vertical elements mounted onto horizontal wood should have at least a 15 degree angle. Sharp edges must be rounded (radius > 2 mm).
If the greying process has already begun, degrey the surface with Osmo Wood Reviver Power Gel and refinish with 2 coats of Osmo UV-Protection-Oil Tints.
To achieve the UV protection factor 12, it is necessary to apply 2 coats of UV-Protection-Oil Tints. With only one coat on untreated wood, the life of the coating is significantly shorter.
Osmo UV-Protection-Oil Tints is furnished with biocides and therefore it is only to be used in outdoor areas. The added active ingredients delay or minimise the risk of algae and fungal attack. For effective protection, two coats are to be carried out. In accordance with the latest technical research, permanent protection against algae and fungal attack cannot be provided.
Osmo UV-Protection-Oil Tints 429 Natural protects wood nearly invisibly. The natural wood tone is preserved using a white coloured tint. When applied correctly, it does not enhance the the natural colour tone of the wood (no permanent wet effect).
On dark/reddish wood species, Osmo UV-Protection Oil Tints 429 Natural is visible as slightly white chalky surface. Over application of Osmo UV-Protection-Oil Tints 429 Natural may also appear slightly white and chalky, especially over very textured surfaces. Always remove excess white pigment before allowing the surface to dry. A trial application is always recommended.
Using power washers will severely decrease the coverage of the finish and general or multi-purpose cleaners will increase the frequency of maintenance and recoating.
Regular Cleaning: Damp cleaning with Osmo Spray-Cleaner.
Occasional Maintenance: If necessary, intensive cleaning and refreshing using Osmo Wood Reviver Power Gel or Osmo Gard Clean.
Recoating: Simply re-apply one coat onto the clean and dry surface when signs of wear become visible.
For all other wood types not mentioned, always trial apply first.
- Oak: UV-Protection Oil Tints 425 Oak (for a darker shade) and 429 Natural (for a lighter shade) are optically suitable.
- 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.
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.
RECOMMENDED AFTER WEATHERING PERIOD
For the following wood types, a weathering period is recommended. New or sanded wood requires at least 12 weeks (approximate) exposure to the exterior elements before application.
After the weathering period, it’s generally recommended to de-grey the surface with Osmo Wood Reviver Power-Gel and clean the surface from the extractive content before application, always trial apply!
For all other ingredient-rich hardwood species not mentioned may require a varied period of exposure. Please contact us for further information.
- Cedar: UV-Protection Oil Tints 428 Cedar is optically suitable.
- 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.
- 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.
