"Has anybody used Venetian plaster by Fresco Srl, Italy to create 3xD Murals or Fresco?"

it is hard to tell how "venetian plasters" would behave if being painted on while wet, since the ingredients are usually a trade secret. although every lime based plaster is made of 2 main ingredients - lime putty and sand (or marble meal) the additives that are put in for ease of application and extending of a shelf life (every manufacturer has it's own set), will shrink the painting time dramatically and may render plaster almost unpaintable in buon fresco. Either way the painting time will be very short so paintings will have to be simple and fast

Most suitable plaster for fresco is a traditional mixture of 1 part of aged slaked lime and 2 parts of fine river sand.
