Granulation Medium is applicable when you want to add interesting dimensions to otherwise flat areas, as it gives a mottled appearance to colours which normally have a smooth wash, or enhances the effect of granulating colours. This medium is useful for all water colour techniques, including landscape painting, seascape painting and figurative work. For maximum effect, dilute water colours with the medium alone. By diluting the colour further with water, a variety of results can be achieved. Granulation Medium is resoluble simply by re-wetting. Granulation is also greatly affected by different water colour papers. For maximum granulations use Rough paper and for less granulation usea medium texture surface.
