Is gesso necessary for oil painting?

If you’re starting with an unprimed or linen canvas, it’s recommended that you first prime your surface with an oil-friendly gesso. Primer also keeps the canvas from turning brittle with age, as over time oil oxidizes and makes the surface of the canvas more delicate and prone to cracking.

Gesso prepares (or “primes”) the surface for painting, making the surface slightly textured and ready to accept acrylic paint. Without gesso, the paint would soak into the weave of the canvas.

Why is my oil painting cracking?

Oil paint dries under the influence of oxygen and light. This is a chemical process. Once the paint is dry this oxidation process does not stop but continues in an ageing process. Eventually this can be visible as cracking.

How can I prime my canvas without gesso?

Brush paint directly on unprimed — no gesso applied — canvas with acrylic artist’s colors. Apply artist’s varnish to your finished acrylic painting to prevent dirt and mildew from working their way into the fibers. Apply a coat of gloss or matte medium to the painting to give it a protective shield.
