ABSTRACT:
An apparatus for applying an exterior layer of cementitious material to a partially assembled prefabricated modular building panel of the type having a rigid framework composed of a plurality of rigidly interconnected stud members and a support base secured to the framework having an outer surface configured to retain the cementitious material. The apparatus includes a conveyer-like support bed for fixedly holding the panel framework in place, and a continuously moving elongated toothed screed which spreads and textures the cementitious material over the outer surface of the panel support base. The screed is driven by a cable arrangement which insures constant tension and prevents tracking of the cable. The vertical position of the screed blade may be adjusted with respect to the layer of cementitious material to provide a uniform thickness on the panel. As the screed traverses the panel surface it is simultaneously vibrated to work the cementitious material into the metal lath. In an alternate embodiment, the scraper screed may be replaced by a roller for working aggregate material into the cementitious coating.
