All Stevenson Acrylic Paints are rated as “Professional Artist Quality” and are manufactured with 100% acrylic emulsion. The pigments used in their manufacture are composed of traditional inorganic and modern organic pigments, all possessing a high degree of lightfastness. Only high-strength, permanent pigments are used in their formulation. They are quick-drying, flexible, non-cracking and compatible with most other brands of acrylic paint. These heavy-bodied paints can be thinned with acrylic mediums or water, to produce watercolour or smooth, colour-field effects. When applied straight from the tube or jar, brush strokes are easily retained and strong, sharp, impasto effects achieved. The 64 colours of the Stevenson acrylic line dry to a uniform satin finish.
