I have a hardwood, which product do you recommend?
For ingredient-rich hardwoods (such as Mahogany, Teak, Iroko etc.) we recommend using Osmo Wood Wax Finish Extra Thin for interior wood.
Although for most exterior ingredient-rich hardwoods we recommend exposing the surface to external elements of weathering for at least 12 weeks before application.
The high natural oil content of these types of wood are likely to resist the penetration of any further oil until it has extracted the majority of its natural content during the weathering period.
Although the wood is unlikely to grey during this time, it may be necessary to apply Osmo Wood Reviver to restore the surface before application of a suitable treatment.
