WHAT is acrylic slow dry Medium?

Derivan Retarder is a slow drying medium for acrylic paint that will counteract the fast drying power of acrylic paints, creating a possibility for wet on wet or other techniques which would typically require oil paints. When appropriately used, Derivan Retarder will keep the colour moist from half an hour to one day's worth of working time. But too much retardant can prevent layers from drying correctly and cause damage to your painting- so it's important not to apply too much. The recommended amount is up to 5% to your acrylic paint. 

HOW TO USE AN ACRYLIC SLOW DRYING MEDIUM 

There are two ways to use this acrylic slow drying medium. The first is to use up to 3% the Derivan Drying 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).

Additions of drying retarders to mixing water may be used in water colouring, water wash effects, stain painting and hard-edge techniques where it assists in pigment wetting, rapid colour diffusion and penetration.
