The technique of beginning a painting by blending white into the background can pose many problems, however if done correctly, it can produce beautiful effects.
Golden Acrylic Paint Manufacture doesn’t create mixing white. So, if you are a Golden fan, there has to be away around this…. Ah, yes, use some gesso and water, with a touch of glazing medium. This will blend without lightening the colors too much. Much of the time, you are just blending distant trees for landscapes with this technique.
In order to do this technique without complaint, spray the canvas with an atomizer, and load your brush with gesso and a bit of acrylic glazing medium and crisscross the brush across the top of the canvas, gradually getting less and less toward the end of the canvas.
It should stay wet for at least a half hour in more moist areas, like Oregon, and about 15 minutes in dry areas like Southern California.
