Ideally, the paper should be sized with gesso or a similar product to help create a barrier between the two surfaces. This can be done by applying a thin layer of the material to both the front and back of the paper before beginning work. This will prevent the acrylics from bleeding through and will also give you a smooth surface to work with. You can find gesso in most art supply shops or at online retailers. It is important to use a gesso that is designed for use with acrylic paint rather than a typical primer found at a hardware store which will contain harsh chemicals that could be damaging to your health.

From Brush to Paper: Creating Stunning Effects with Acrylics on Watercolor Surface

You should use a heavy paper to prevent it from buckling and curling as the acrylics soak in. Look for a professional-grade watercolor paper that is made of cotton fiber and is acid-free. This will ensure that the paper doesn’t yellow over time and makes it suitable for a wide variety of painting styles.

You can also try using oil painting papers for a more traditional finished appearance. These papers are typically thicker than traditional watercolor paper and have a rougher texture to aid in the binding of the acrylics. They are also available in a wide range of sizes to suit your needs.
