Gesso

Gesso is a specially formulated primer used to prepare surfaces like canvas, wood, or other materials for painting. It creates a smooth, absorbent layer that helps paint adhere better and prevents it from soaking into the surface. Typically made from a mixture of chalk or plaster, binder (such as glue or acrylic), and water, gesso can be applied in multiple coats to achieve the desired texture. Artists use gesso to ensure long-lasting, vibrant paintings, and it also helps to prevent imperfections in the final artwork.
