Matisse Drying Retarder 250ml MM1

Retarder as the name suggests, retards or slows the drying time of the paint. There are two ways to use this medium. The first is to use up to 3% Retarder to colour; this will result in a slightly more fluid colour that will stay wet for much longer. The second method is to put the Retarder in a hand pumped spray bottle (atomiser) and spray it onto the painting you want to keep wet. (The spray bottle should create a mist not a hard squirt).
