Also called fresco secco or fresco finto, this is a technique of wall or mural painting wherein casein, tempera or oil paints are mixed with lime water and applied to dry plaster as opposed to the wet plaster used in the true fresco method. If the pigments are mixed with lime or the plastered surface of the wall is soaked with slaked lime prior to painting, the process is called lime-painting. Due to the absence of a binding technique, secco paintings do not penetrate the surface of the wall and are considered less durable compared to fresco buono.
