Acrylic gouache paint dries flat and matte, while acrylic paint typically dries with texture and some areas of translucency. Acrylic gouache was designed to look like traditional gouache (with a creamy, flat finish), but has the same base, or binder, as acrylic paint.
Can you substitute acrylic for gouache?
Gouache is very comparable to both acrylic paint and watercolor paint but is its own entity. Gouache paint is opaque but becomes translucent when water is added. In comparison to acrylics, gouache paint dries quickly but can be reworked on its surface long after the artwork is completed.
Is all gouache acrylic?
Acrylic gouache is opaque, matte acrylic paint. Like acrylic, it also sticks to many surfaces with great adhesion. It is called gouache because it has a similar look and coverage to traditional gouache, but it is different because it is waterproof after it is dry and traditional gouache is not.
