The best Osmo finishes for walnut indoors
The best way to treat walnut indoors is with Osmo TopOil or Blanke Was, because walnut can fade in bright light, and an oil or wax finish lets that change happen evenly while keeping the grain clearly visible.

Oil for walnut indoors
For walnut indoors, use Osmo TopOil on tables and furniture and Osmo Blanke Was on floors. Both penetrate the wood and accentuate the lively grain and warm brown tones, whereas a lacquer layer makes the wood look flatter.
Which oil for which walnut surface
Walnut is mainly used for dining tables, desks and cabinets. For these surfaces, choose TopOil: food safe, resistant to coffee, wine and water, and easy to touch up locally without sanding. Treat a walnut floor with Blanke Was, applied thinly along the grain.
Colour variation in the wood
European walnut often has a wild figure with grey-brown, golden brown and sometimes almost black areas, and lighter sapwood at the edge of the board. A clear finish shows off that character. Always test a finish on offcuts first.
Choose the right sheen level
Walnut slowly fades under bright light and becomes warmer in tone; an oil lets this happen evenly. On this dark wood, a fully matt oil can leave a white haze. So for TopOil choose 3028 satin matt rather than 3058 matt.
Caring for oiled walnut
Keep tables and furniture clean with the Spray-Cleaner. For looking after a tabletop there is the Tafel & Keuken onderhoudsset. Mop a floor with Wisch-Fix. This keeps the grain of the wood clearly visible for a long time. For American walnut, take a look at American walnut indoors.
