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.
