Holbein Acryla Gouache is an opaque and highly-pigmented paint which dries to a velvety-matt finish.
In terms of handling and mixing, it behaves like traditional gum arabic gouache, but because it is made with an acrylic resin binder, it is water-resistant once dry. This facilitates layering, as fresh paint layers can be laid down without the risk of bleed-through from the lower layer. Acryla Gouache dries quickly and with minimal colour-shift; what you see wet is what you get once the paint has dried.
