The process involves creating a primer, typically composed of a binder, pigment, and filler, designed to prepare a surface for painting. This ground creates a receptive layer, offering improved adhesion for subsequent paint layers and contributing to the longevity of the artwork. It provides a consistent, slightly textured surface that prevents paint from sinking into the support material, ensuring vibrant and accurate color representation. For instance, preparing a canvas often includes the application of this primer to prevent oil paints from damaging the fibers.
A properly prepared surface offers several benefits. It enhances paint adhesion, prevents paint absorption, and provides a uniform texture, leading to improved color vibrancy and longevity of the artwork. Historically, this preparation was often a labor-intensive process using traditional materials like rabbit skin glue and chalk. The use of such a ground extends back centuries, showcasing its enduring importance in artistic practice. This preparation is considered essential for professional-quality paintings, and its careful application is crucial for archival quality.
