, typically around one-third varnish and the rest oil.

Uses

When applied in coats over wood, Danish oil cures to a hard satin finish that resists liquid well. As the finished coating is not glossy or slippery, it is a suitable finish for items such as food utensils or tool handles, giving some additional water resistance and also leaves a dark finish to the wood. Special dyed grades are available if wood staining is also needed.

Application

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. Danish oil provides a coverage of approx 12.5 m²/ l (600 sq. ft./gallon).
