Drying Retarder MM1 Matisse 250ml

Slows drying time when added to Matisse paints. 

Additions of MM1 Drying Retarder may be used in watercolouring, water wash effects, stain painting and hard edge  techniques where it assists in pigment wetting, rapid colour diffusion  and penetration. On raw canvas, the addition of 3-5% MM1  Drying Retarder, pre-diluted with water, will improve the mixing of  inorganic pigments, oxides, earth colours, titanium dioxide and metallic  pigments.

MM1 Drying Retarder will slow the evaporation of water from the  paint. However, excess amounts of MM1 Drying Retarder (over 10%) will severely slow “cross linking” of the acrylic. Therefore, even though the  paint may look dry (and indeed all the water will have gone from the paint), it will not have “cross linked” or “cured” so it is able to be  re-wet, i.e. with a wet brush or cloth. This allows the Matisse acrylic colours to be used just like watercolours.
