Plastering Italian style

They set up a mixer in the garden with a stack of plaster bags. One guy just fed the plaster and water into the mixer which then pumped the mixed plaster up a pipe through the living room window. The guy at the other end piped the plaster onto the walls. The plaster was then smoothed. When it had partially set, they then went round making it flat and roughing it up. All done in one day.
