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
- Iroko
- Mahogany
- Teak
- Walnut
- Ipe
- Merbau
- Wenge
- Rosewood
- Sycamore
- Sapele: approx. 3-4 weeks exposure
- Larch: approx. 2 weeks exposure. Application of WR Base Coat is recommended before use.
- Pressure-Impregnated Wood: Approx. 12 weeks exposure to heavy rain (winter periods) or approx. 6 months exposure to light rain (summer periods) to wash out the salts used for impregnation.
Important: please check and ensure moisture content is below 20% prior to application.
Top Tips
- For new resinous wood species, please allow approx. three months exposure to the outside elements prior to application.
- The transparent colour tone of the finish will be influenced by the wood’s natural colour, and testing first is always recommended.
- Over application can increase the drying times.
- Use biocides safely. Always read the label and product information before use.
- Recommended application amount is approx. 35 ml/m².
- Drying time of 4-6 hrs after the first coat, but is 12 hours after both coats have been applied.
- If the subsurface does not absorb the wood finish uniformly, the colouration will be uneven. For an improved, consistent and matted surface, we recommend retreating the surface with [701 Clear]. Thereby glossy spots are matted and an even appearance is created.
- Grey wood looks classically beautiful, to allow the natural greying process to occur, apply [701 Clear].
- For more grey colour tones for an aged and weathered effect, see Osmo Natural Oil Woodstain Effect.
- Multi-purpose cleaners such as washing up liquids and detergents are highly detrimental to the finished surface and is not recommended to be used as discolouration or staining may be possible.
- Other household cleaning products such as vanish, bleach, baking soda etc. are likely to cause severe discolouration or staining.
- Many wood species contain water-soluble coloured extractives which may leach out naturally when weathered.
