AK gouache paints are made from opaque pigments and a water-based binder, creating vibrant and saturated colors perfect for matt, opaque layers. They can be applied over acrylics, enamels, oil paints, and on surfaces like plastic, paper, and cardboard. AK gouache paints are excellent for matt rust, earth, and other weathering tones. How to Use AK gouache paints can be diluted with tap water for various weathering effects. A major advantage is their reactivability with water, allowing for further blending even after drying. These paints dry quickly. To prepare the surface, simply clean it with soap and water before application.
