Abstract: A system and method of making a plaster panel to use in the construction of a wall of a building in a relatively faster, easier, more efficient, and more precise manner for either interior or exterior walls is disclosed. The created plaster panels may include a slab of cementitious composition including a mixture of sizes of cut expanded polystyrene, a quantity of monofilament fiber, and a binding agent. At least one layer of a mesh may surround the slab, wherein the resulting panel is light in weight, flexible and strong. Such panels may be fixed in place to a building frame by suitable fasteners such as nails or screws, while causing little or no fracturing of the panel.
