Properties and Benefits: Pigments have traditionally been added to lime coatings according to local availability. Today, artists and decorators have a huge palette to choose from. Ochers and earths produce warm shades and are unaffected by UV radiation. Oxides produce cool shades and are often used in small quantities with Ochers to expand the range of colors. For limewash, pigments are added after the water and lime are thoroughly mixed. Wet the pigment in an equal amount of water to form a paste. This paste can be left to soak overnight if desired. Add the pigment paste to the limewash and stir — an electric paint paddle is recommended for complete dispersion. How much pigment you add depends upon individual pigment density, intensity of color desired, and chosen recipe.
