Liquitex Slow-Dri Acrylic Mediums

Retarder is a thin water-based product designed to slow down the drying time of acrylic paints. It is ideal for using with acrylic paints when plain-air painting. Mixed with acrylic colors and mediums at up to 15%, it increases open-time and allows for greater manipulation. NOTE: Using a larger proportion of Retarder to color can negatively effect the permanence and film integrity of the paint. Amber coloration may occur as the product ages in the jar.
