MATISSE MM1 250ML DRYING RETARDER
Matisse Drying Retarder is used to slow the drying time of paint. This medium can also be used in water wash effects, stain painting and hard edge techniques. This medium assists in pigment wetting, rapid colour diffusion and penetration. Slowing the evaporation of water from your paints, use no more than 8% of the retarder as more than this may leave paint water sensitive.
