The Best Way to Seal Gouache Paintings: With Cold Wax!

If you want to make a gouache painting on wood or a hard panel, you'll need a way to protect it from water or other liquids which could reactivate and ruin your painting.  The problem that happens when you just varnish your gouache painting is that is looses that matte, velvety, chalky look. 

​However, when you use cold wax, you not only seal in and protect your gouache painting, you also maintain its wonderful matte texture.  In this video by Catherine Graffam, you can see what supplies she used how she applied the wax on her gouache paintings.  Check out the whole video at the link above.
