The preparation of a painting surface with a specific coating is a fundamental step in creating durable and high-quality artwork. This process involves applying a substance, often gesso, to a raw canvas to seal the fibers, create a receptive texture, and prevent the paint from sinking into the fabric. An example of this process involves evenly coating a stretched linen canvas with two to three layers of acrylic gesso, allowing each layer to dry completely before the next application.
This preliminary action significantly impacts the longevity and appearance of the finished painting. It provides a stable and uniform surface, preventing discoloration and cracking over time. Historically, artists have used various materials, from rabbit skin glue to oil-based primers, to achieve the desired surface characteristics. This careful preparation ensures optimal paint adhesion and allows for better control over color and texture.
