An improved weathered stone panel is provided that is strong and durable, but flexible enough to accommodate curved surfaces, is suitable for water-based applications, and is lighter and less costly to ship while still maintaining the aesthetically pleasing smooth texture of the panel. The improved method for manufacturing a weathered stone panel includes preparing a base mixture comprising wood glue and plaster of paris and applying the base mixture to a substrate. The method further includes cutting the substrate to create panels of a desired size, applying light air movement to the panels until the panels are dry, applying an acrylic base to the panels, applying light air movement to the panels until the panels are dry, cutting the panels to preferred sizes, manipulating the panels by hand until at least one crack is created in each panel, applying a glaze to the panels for coloring, and finally drying the panels.
