General
all-purpose ground, all purpose ground, multipurpose ground definition
All-purpose ground (multipurpose ground) is a prepared panel/canvas created for use with several types of media, including watercolor, polymer and oil. Every painting medium contains its own particular preference for its best use; therefore multipurpose panels and canvases cannot compare to the superiority of a panel/canvas prepared for a particular purpose. However, traditional gesso panel can be modified for use with every artist's type of paint.
