How long does Artists Acrylic remain workable or open?
Artists’ Acrylic colours do remain usable on the palette for slightly longer than many other acrylics. This working time has been increased by 20% compared to the previous range; Finity. This means even less waste on the palette and longer time on the canvas for blending. Colours will remain workable on the palette for over 30mins. The working or open time will be extended further by mixing the colour with Winsor & Newton Acrylic Retarders. Either alternatively or in addition to retarder, the Winsor & Newton Acrylics Palette can be used. This consists of a lidded tray into which a paper membrane is placed and moistened keeping the colours usable for days, provided the paper is kept moist and the lid replaced at the end of every painting session.
