SUMMARY. Gesso is the primer that helps your paint stick to the paper or fabric (or other) surface, and also keeps the paint from soaking into your journal page. Gesso can also add body or strength to the paper, so that you can apply heavier elements such as layers of collage. You don't have to use gesso, ever.hat it is and how to use it. Gesso is a useful option for art journaling. It's also used for painting and mixed media art. I use gesso often. However, many (perhaps most) artists never use gesso in their journals.
