What is Gamblin Cold Wax Medium used for?
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.
Can you varnish Cold Wax Medium?
If your Cold Wax/Oil painting contains less than 1:3 cwm:oils, you can varnish with Gamvar. Instead, varnish with a thin rubbed-on coat of Cold Wax Medium. Allow to dry 24hrs for a matte finish or gently buff after 4-6hrs with a soft cotton cloth for a satin sheen.
How many coats of Gamvar should I use?
When using Gamvar Satin or Gamvar Matte, it is best to apply a single thin layer and not to apply multiple applications. Multiple coats of either Satin or Matte can dry to a patchy finish or tacky feel, as the 2nd application will reconstitute the matting agents in the first coat.
How do you thin out Cold Wax Medium?
Use a brush to pull some wax/oil away from the pile, use a small amount of Wax Solvent to thin the mixture as desired.
Does Cold Wax Medium dry?
Cold wax medium, or CWM, is an oil painting medium. It is composed mainly of beeswax, with a small amount of solvent to soften it and other ingredients to aid in drying time. It has a soft, paste-like consistency at room temperature and dries to a matte surface.
How do you use medium wax?
Simply add a blob of medium to your palette and add in as much pigment as you will need. Painting knives are excellent for mixing in the colour thoroughly. Alternatively, you can apply a layer of wax to your paper or canvas and then sprinkle pigment on top. The wax is sticky, so the pigment will adhere quite well.
Can you paint over cold wax?
It helps to first coat your painting with a layer of clear acrylic gesso as this has some texture and helps the wax to adhere to the acrylic surface. You can also paint over cold wax once it is dry with straight oil paint without fear of cracking so the traditional ‘fat over lean’ doesn’t apply here.
