Aerosol paint (also called spray paint) is a type of paint that comes in a sealed pressurized container and is released in a fine spray mist when depressing a valve button.
However, in the cases in which you are using an unprimed canvas, it must be primed in order to paint on the canvas. Gesso is the most common type of primer. It is generally a white paint mixed with a binder that seals the canvas, though it also comes in black, gray and other primary colors. Gesso will make the canvas a bit stiffer and smoother. Liquid gesso is applied with a paintbrush, lightly over the entire surface and sides.
