Grumbacher Acrylic Medium Modeling Paste - 32oz
This is a flexible, durable paste for creating textured surfaces to be over-painted with oil or acrylic paints. Apply it to a canvas, wood, cardboard, plaster, concrete, masonry, and other surfaces.
For heavy impasto effects, mix it with acrylic paints (do not mix with oil paints). It may be modeled, shaped, or textured before hardening, and cut, sanded, or carved when thoroughly dry.
