Explanation:

Gesso has been practiced by artists and craftspeople for eras to make boards, canvas, or other exteriors for painting or gilding. It is first been produced in Italy because the term Gesso means ‘chalk’ in Italian. Gesso was created using chalk dust and a powdered white pigment associated with animal-skin glue.

The application of Gesso as a primer to let the paint to adhere enduringly to the surface of the painting.  Gesso is very related to white acrylic paint, only thinner. It drains hard, making the surface stiffer. Gesso provides the surface for painting, making the surface slightly textured and ready to accept acrylic paint. Without gesso, the paint would soak into the weave of the canvas.
