The Vallejo Dipping Formula is a non-toxic and non-flammable acrylic wash used to enhance details and shading on models and miniatures.
For armour, vehicles, planes, ship, figures and war game figures. All surfaces exposed to sun, wind and dust, rain and snow experience a colour change, a loss of intensity, a dulling and general fading which, however, is not even or overall. For the model painter, these colour changes are very difficult to reproduce and to achieve these effects on a model, washes or filters are the perfect solutions. The washes are always needed to blend the edges of the colours on a model painted in various camouflage shades. The colours can also be mixed together to achieve further shade variations and can be used with an airbrush or brush, according to the model and desired effect.
Model Wash can be mixed with pigments to achieve a wide range of effects such as oil and flaked rust, mud, earth, dust, moss, etc., and when mixed with acrylic colours, they further help achieve the impact of heavy wear and weathering. The washed have been formulated with a modified acrylic resin. The superficial tension is similar to that of the traditional solvent-based washes and filters but with the advantage of working with a water-based medium. The 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 are cleaned with water.
