How to Use Acrylic Underpainting & Then Oils
- 1). Apply two to three coats of acrylic gesso to the canvas with a wide brush. Allow to dry to the touch. This may take up to an hour.
- 2). Use a brush or painting knife to apply the underpainting. This may be one layer of acrylic paint, several layers of acrylic paint, or acrylic medium. Allow to dry between coats and after the final coat of the underpainting. Drying may take 2-4 hours for thick coats of medium or layered paint.
- 3). Clean all of your acrylic brushes with water and soap to avoid mixing the acrylic paint with oils.
- 4). Paint as usual with oils. As the top layers of your painting, the oil paints will contact the air, oxidize and cure normally.
