A ceiling system including a base ceiling structure for suspending from a structural member of a building, a substrate attached to the base ceiling structure, and a sprayable reinforcing material adhered to the substrate. The sprayable reinforcing material and the substrate together form a self-supporting composite material. A method of forming the coated ceiling structure includes the steps of providing a base ceiling structure having an outer surface, applying a foam material in a fluid state to the outer surface of the base ceiling structure, and solidifying the foam material to form a rigid reinforcing layer on the base ceiling structure. Alternatively, the base ceiling structure is a non-self-supporting material, and a reinforcing material is sprayed onto an outer surface of the base ceiling structure. The reinforcing material and the non-self-supporting material together form a self-supporting composite structure.
