Understanding the drying times for acrylic paints
Galeria: Thin films of colour will dry in 10-20 minutes whereas thicker films can take an hour or more.
Professional Acrylic: Thin films of Professional Acrylic will dry in 20-30 minutes and thicker films can take an hour or two. This will vary according to environmental conditions.
Professional Acrylic colours remain usable on the palette for slightly longer than many other acrylics. This working time has been increased by 20% compared to the previous artist quality Winsor & Newton range; Finity. A longer working time allows artists to have less waste on the palette as well as a longer time on the canvas for blending as colours will remain workable on the palette for over 30mins.
The working or “open time” can 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.
