Schmincke Structuring Paste is used to build structure to paint on with acrylic paint. It is particularly suitable for flexible surfaces such as canvas and paper and can be applied directly from the jar with a palet knife. The mass dries quickly into a white and matte surface and has a slightly stronger absorbency. Schmincke Structuring Paste is an extra light acrylic mass with a firm consistency that is well suited to large surfaces.
