8+ Art Ground Definition: Explained & Defined

In the realm of visual arts, the term refers to the prepared surface upon which an artist applies paint or other media. It is the foundational layer that sits between the support (such as canvas, paper, or wood) and the subsequent layers of artwork. Functionally, this layer serves to create a receptive surface for the paint, influencing its adhesion, absorbency, and ultimately, the artwork’s appearance and longevity. For example, gesso is a common material used to create a smooth, slightly absorbent surface on canvas, allowing paint to adhere properly and preventing it from sinking into the fibers.

Its proper application is crucial for the preservation and aesthetic quality of a piece. A well-prepared one ensures the paint film forms a strong bond with the support, minimizing cracking or peeling over time. Furthermore, it can affect the brightness, texture, and color saturation of the final artwork. Historically, various materials have been employed to achieve different effects, ranging from traditional animal glue sizing to modern acrylic formulations, each contributing to the unique characteristics of the art produced. The choice of substance reflects both the artist’s intention and the properties of the chosen paint medium.
