Washes are perfect for adding shading to models as well as blending colors as a glaze. They can also be used as a quick way to weather your models. The washes have been formulated with a modified acrylic resin so that the superficial tension is similar to that of the traditional solvent-based washes but with the advantage of working with a water-based medium. Average drying time is around 20 minutes. If several layers of wash are to be applied it is best to wait around 40 minutes between applications. Painting tools can be cleaned with water.
