surface on which a mural is painted

The surface on which a mural is painted is commonly called the substrate or support ; in everyday language, it is usually just called the wall when the mural is on architecture.

Common mural surfaces

• Masonry, plaster, brick, and concrete walls are the most typical substrates for outdoor murals.

• Interior murals are often painted on drywall or sheetrock, which provides a smooth architectural surface.

• Some artists paint on panels (such as wood, aluminum, or fiberglass) in the studio and then mount these panels as the mural surface.

Art terminology

• In art terminology, the substrate is the underlying surface that receives the paint in a mural or any painting.

• The word support is also used in painting to mean the physical base—such as wall, canvas, board, or panel—on which the artwork is created.
