EGG LIME PLASTER WALL
In the past, fresco painters often used egg tempera, which is pigment mixed with water and egg. This formed a very tough and durable paint. Egg tempera, however, is time-consuming to mix and somewhat more difficult to work with than other kinds of water-based paints. Ordinary modern acrylics will work with fresco painting, as well as modern tempera paints, which bear the same name but have a somewhat different composition from egg tempera.
