In the foreground, Anthony wields the "Tirolessa", a plaster sprayer which operates with air pressure from a conventional compressor. The sprayer is a plaster delivery system only, not a finishing tool, but it speeds the work along nevertheless. The Tirolessa, made in Mexico, is well-designed, sturdily constructed and reasonably priced. For more information, visit Paul Sarnstrom's site.
In the background, Bill compacts and trowels the plaster smooth. This first coat is a clay-rich mixture with plenty of chopped straw to help control cracking.
