Matisse Open Medium -250ml

Matisse Open Medium - MM31 is formulated to be mixed with either Matisse Structure or Matisse Flow acrylic colours to assist in prolonging drying time while maintaining the consistency of the paint. When mixed with Matisse Structure, they will retain their impasto quality, while Matisse Flow Acrylics will keep their smooth flowing feel with added body but not viscosity. Optimal for painting outdoors or in particularly hot weather, MM31 Open Medium allows the paint to be blended on the painting surface for longer. Artists will be delighted with the way this medium makes their paint handle, so smooth and buttery. Be surprised by the glowing satin finish that this medium impartsto the paints.

Mixing Ratios: As little as 10% MM31 Open Medium to the paint, will lengthen the working time, allowing satisfying, smooth blends. By choosing to use smaller amounts of medium, the blending time is increased, but drying time is not drastically increased. However, a larger amount of Open Medium will dramatically increase the working time of the paint. The maximum retardation of drying time is reached with an equal mixture of paint to medium. Beyond this point, any further additions of MM31 Open Medium will result in minimal increases of drying time but may reduce water fastness of the dried paint. However larger proportions (more medium than paint) will give transparency and will aid effective layering
