What the hey is GESSO?
Paint adheres to surfaces via a chemical bond. If this chemical covalent bond is absent, the paint will peel or crack off. Gesso is a primer that makes sure paint (acrylic or oil) sticks to a surface. You can use Gesso on rocks, boards and glass as well. It also seals the fibers in canvases to protect them from moisture and chemical damage. In the old days, they used rabbit glue (made by boiling rabbit skin and bone), but now days the chemist have made it much easier on us. Keep in mind there are different price levels of Gesso as well. The cheaper ones are for studio or general use and are relatively thin. The pricier ones are thicker so you don’t need as many layers.
