Stone surfaces were prepared by whitewash, or if rough, a layer of coarse mud plaster, with a smoother gesso layer above; some finer limestones could take paint directly . Pigments were mostly mineral, chosen to withstand strong sunlight without fading . The binding medium used in painting remains unclear: egg tempera and various gums and resins have been suggested . It is clear that true fresco, painted into a thin layer of wet plaster, was not used . Instead the paint was applied to dried plaster, in what is called "fresco a secco" in Italian . After painting, a varnish or resin was usually applied as a protective coating, and many paintings with some exposure to the elements have survived remarkably well, although those on fully exposed walls rarely have .
