Which statement about acrylic as a base for oil painting is accurate?

• A. Acrylic can be used as a base for oil paintings but cannot be painted on top of the oils.
• B. Oil can be painted on top of acrylic directly
• C. Acrylic cannot be used as a base for oil
• D. Should be avoided altogether

Answer: (A)

Starting with an acrylic base gives oil painting a compatible, stable ground. An acrylic ground or gesso dries to a firm, non-greasy film that seals the canvas and provides good tooth, helping oil paint grip and layer smoothly. That’s why acrylic is commonly used as the base for oil painting: you get reliable adhesion and a predictable surface for the oil layers to sit on. However, applying acrylic over an existing oil layer is not recommended because oil creates a film that water-based acrylics don’t bond to well, leading to cracking or peeling. So the statement reflects this practical rule: you can use acrylic as a base for oil paintings, but you shouldn’t paint on top of oils with acrylic.
