I want to add some extra protection to my piece of furniture – what would you recommend?
For the first coat, we recommend Osmo Hardwax Oil Effect Natural Matt 3041, which contains a small amount of white pigments to keep the light wood look.
Once the wood has dried sufficiently, sand it with fine-grain sandpaper. We then recommend applying a second coat of Osmo Polyx-Oil 3062 clear matt for a complete treatment and protection of the surface.

The wood may initially feel a little rough after treatment, as the wood fibres open up slightly due to the wax. However, this effect will disappear over time.
