At the same time as the white pigment zinc white was introduced in building painting in 1851, a lead-free “linseed oil paint varnish” was launched, i.e. a traditionally boiled linseed oil with manganese oxides as a drying agent, which makes the linseed oil dry efficiently.

The product can be used as a binder for linseed oil paint both externally and internally. It is particularly suitable for oiling kitchen worktops.

Best results are obtained if it is used undiluted, heated to about 70 degrees. It can also be applied cold, in which case it is diluted with between 30-50% turpentine. In both cases, the excess is wiped off after about 30 minutes and the surface is polished to a silky shine with a linen cloth.
