Wet plaster painting, also known as FRESCO, is an ancient technique of painting on wet plaster. It involves applying pigments to a layer of wet plaster, which then dries and becomes part of the wall. This method of painting has been used since the time of the ancient Greeks and Romans, and is still used today in many parts of the world. FRESCO is a durable and long-lasting form of art, and can be used to create beautiful and intricate works of art.
