As an oil painting medium, Cold Wax Medium can be used to make oil colors thicker and more matte. Its soft paste consistency can be thinned to brush consistency by dissolving in a small amount of Gamsol. The surface of paintings made with Cold Wax Medium will become only as hard as a beeswax candle. Please note, painters who are using more than 1/3 cold wax medium to 2/3 oil paints should paint on rigid supports (e.g. wood painting panel) or paintings may crack when moved. By mixing 1/2 Cold Wax Medium and 1/2 Galkyd Gel, painters can paint on flexible supports like stretched canvas.
You may add Cold Wax Medium to Galkyd oil painting mediums or Drying Oil (linseed/Stand) to reduce gloss. Use up to 25% wax to reduce gloss in a painting medium without adversely affecting the strength and flexibility of the medium.
When adding wax to thicker mediums like Galkyd Gel, Neo Megilp or Solvent-Free Gel, blend directly with a palette knife.
When adding Cold Wax to a fluid medium, thin it first with Gamsol. On a separate palette, add a small amount of Gamsol into some Cold Wax and blend thoroughly with a palette knife until you achieve a very soft paste, nearly slurry consistency. This is your matting agent. Add the desired amount of Cold Wax slurry into a premeasured amount of fluid painting medium. Mix/shake thoroughly until you can hold the jar up to the light and it looks uniformly cloudy (no wax bits floating about).
Straight Cold Wax Medium can be applied to a dry painting as a removable, matte varnish. Once applied, the Cold Wax can be left to dry for a matte finish or gently buffed for a soft luster. Cold Wax Medium can also be used to reduce the gloss level of Gamvar Picture Varnish.
