"Plaster" an ancient Greek application term meaning "to Daub on" is used to describe interior plaster dating back to 500 BC. When it became popular to apply plaster on the exterior of structures the term "Stucco work", meaning exterior plaster, was developed to describe it as the interior products/materials would not withstand the elements. For thousands of years the plasterer performed all phases of the work involved in producing the complete job and was regarded as an artist with the highest prestige of all the construction trades. The plasterer developed finished walls, ceilings, and in many cases floors.
