Danish oil

It can provide a hard-wearing, often water-resistant satin finish, or serve as a primer on bare wood before applying paint or varnish.

[1][2] When applied in coats over wood, Danish oil cures to a hard satin finish that resists liquid well.

Compared to varnish it is simple to apply, usually a course of three coats by brush or cloth with any excess being wiped off shortly after application.

The finish is left to dry for around 4–24 hours between coats, depending on the mixture being used and the wood being treated.

[3] Rags used for Danish oil, like those used for linseed oil, have some potential risk of spontaneous combustion and starting fires from exothermic oxidation, so it is best to dry rags flat before disposing of them, or else soak them in water.
