Grattage: The Surrealist Artistic Technique

Grattage is a 20th-century painting technique closely associated with the Surrealist movement. The term derives from the French verb gratter, meaning “to scrape” or “to scratch,” and refers to a method in which paint applied to a surface is partially removed using pointed tools or everyday objects, revealing underlying textures or colors. The resulting surface exhibits abstract and unpredictable forms, where chance and artistic control interact to produce complex and original compositions.

Origins & Development with Max Ernst

Grattage emerged between 1926 and 1927 through the work of Max Ernst (1891-1976), who conceived it as a pictorial extension of frottage, a technique he had explored earlier with paper, pencil, and textured surfaces. In frottage, impressions are obtained by rubbing graphite over irregular materials, whereas grattage applies the same principle to oil paint. Ernst layered paint on canvases placed over textured supports—such as veined wood, metal meshes, rough surfaces, or fragments of glass—and then partially removed it using spatulas, blades, or other tools. This process produced unforeseen, chance-driven effects, which the artist could either leave in their spontaneous form or rework into figurative elements.

The technique is closely aligned with Surrealist poetics, founded on the principle of psychic automatism and the liberation of the unconscious. Grattage allowed access to unforeseen images, stimulating the imagination and evoking fantastic visions beyond rational control. It provided a means of visualizing internal landscapes in which spontaneity and creative intuition governed the production of forms.
