Used neat to seal semi absorbent paint surfaces like unprimed canvas, for both acrylic and oil painting. Produces matt white surface with a slight texture or tooth.
The gesso primer will ensure the paint does not soak into the surface of the canvas and leave a patchy image. If you are to paint on boards such as Masonite and MDF, then you can exploit the primer or gesso properties by putting it on with a coarse house-painting brush. You can imitate a canvas surface by laying gesso down in one, and then the other direction. Alternatively try stippling the primer on for a different texture.
Use as a base coat for art canvasses when acrylic or oil painting
