Ceiling

An overhead interior surface that covers the upper boundary of a space is a ceiling. It is typically not called a structural part, but a finished surface that hides the underside of the foundation of the roof or the floor of a storey above. Ceilings can be tastefully decorated, and there are many fine examples of ceiling frescoes and artwork, especially in religious buildings. The upper limit of a tunnel may also be called a ceiling.

Plastering Ceiling

Plaster is a building material used for coating, protecting and decorating internal walls and ceilings. It can also be used to create architectural mouldings such as ceiling roses, cornices, corbels, and so on. The most common types of plaster are a composition of gypsum, lime or cement with water and sand.
