For armour, vehicles, planes, ship, figures and war game figures.All surfaces exposed to sun, wind and dust, rain and snow, experience a change in colour, a loss of intensity, a dulling and general fading which however is not even or overall.For the model painter, these changes in colour are very difficult to reproduce and to achieve these effects on a model, washes or filters are the perfect solution.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 variations of shade and can be used with airbrush or brush, according to the model and the effect desired.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 so that 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.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.
