Impasto medium is a full-bodied texture paste that may be thought of as a heavy-bodied paint without pigmentation. Mixtures of this medium with Matisse colours allow artists to create highly textured surfaces with impasto painting techniques. Unlike paints and other gels, MM2 Impasto Medium dries with a very open matrix. This allows all the water to evaporate with less loss of volume during the drying process. Therefore, colours mixed with this medium may be applied much more thickly in a single application than paint alone, without the worry of shrinking and cracking.
