Definition: A canvas fabric or stretched canvas substrate that has been sealed and primed with acrylic.
An acrylic-primed canvas is prepared with one or more layers of acrylic primer (commonly called gesso) to create a painting surface that is ready for use. The primer seals the porous canvas fibers, preventing paint from seeping through, while also providing a textured surface that improves paint adhesion. This preparation is especially suited for use with acrylic paint, but it can also accept oil paint with proper application.
While acrylic-primed canvases are durable, they may become less flexible over time compared to traditional oil-primed canvases. For archival work, conservators sometimes prefer oil priming due to its long history of proven stability. However, modern acrylic priming is widely accepted for professional use.
