Harddrying Oil Kremer Gloss

Harddrying Oil consists of a boiled mixture of resin with linseed oil. It paints out fairly light despite its dark color in the bottle, and imparts hardness, depth and lustre to oil paints and varnishes. Other uses include: As a depth primer on wood, mortar and stone (thinned with spirits of turpentine), a weather- resistant varnish for oil colors, an additive to tempera paints and as a medium for icon painting.
