Welcome to the Stucco & Exterior Coating group of SmartGuy.com. Feel free to interact with other professionals from across the world. You can find professionals, find deals on services, find professionals who might barter, or simple post questions, comments, or suggestions. Stucco & Exterior Coating Contractors apply wet stucco, which then hardens to a very dense solid. It is used as a decorative coating for walls and ceilings, and as a sculptural and artistic material in architecture. Stucco is often used to cover less visually appealing construction materials, such as metal, concrete, cinder block, or clay brick and adobe.
