Atelier Interactive Professional Artists' Acrylics allow artists control of paint open time. The paint, with its smooth buttery consistency, dries satin and can be adjusted and blended longer than conventional acrylics. Wet-in-wet techniques can be achieved by adding more moisture with a fine mist spray. Work can also be done wet-over-dry by simply not adding any more moisture. The curing time is 10 to 12 days depending on the thickness of application and artist's style. 80ml Tube.
