1. Cover your blank canvas with a mixture of gray acrylic - Titanium White and Mars Black.
2. Add your basic shapes and values in acrylic "underpainting" at this stage. NO DETAILS!
3. When the acrylic is dry, "Glaze" your canvas in a thin, transparent coat of oil color (anything on our palette except for Zinc White or Yellow Ochre - both are opaque).
4. Add more layers of oil paint progressing from thin to thicker layers.
*NOTE: If you want to paint over an oil painting because you are not crazy about it anymore (I've done this many times) - NEVER paint acrylic over oil. The painting will peel. You must cover your unwanted oil painting with oil paint. If it is easier for you to obliterate it with a layer of gray - do it in oil. I happen to love painting the new painting right over the one I don't love anymore with color - going right for the shapes and spaces in oil. You can paint oil over acrylic - but never acrylic over oil.
