What plaster technique uses pigments mixed with lime water applied to dry plaster after the plaster ground has hardened?

• A. True fresco
• B. Frescos (fresco Secco)
• C. Encaustic
• D. Tempera

Answer: (B)

Fresco secco is the technique where pigments bound with a lime-water mixture are applied to plaster that has already dried and hardened. This differs from buon fresco, where pigments are painted onto fresh, wet plaster so they fuse with the wall as it dries, creating a more durable result. Encaustic uses melted wax as the binder, and tempera relies on an egg-based binder (often on wood panels rather than dry plaster). So the described approach—pigments with lime water on dry, cured plaster—fits fresco secco.
