Open Medium is formulated to be mixed with either Matisse Structure or Matisse Flow acrylic colours to prolong drying time while maintaining the consistency of the paint. When mixed with Matisse Structure, colours will retain their impasto quality. When mixed with Matisse Flow acrylics, it adds extra body to the paints while keeping their smooth flowing feel.


MM31 Open Medium is ideal for painting outdoors or in hot weather as it allows the paint to be blended on the painting surface for longer. It also imparts a glowing satin finish to the paints.
