Plastering and drywall systems is the development and decoration of buildings using plaster and plaster products.

Plasterers can specialise further, becoming a solid plasterer or fibrous plasterer. Solid plastering is applying wet finishes to internal walls, ceilings and floors. Fibrous plastering involves making ornamental plasterwork such as ceiling roses, cornices and architraves.

The tools used by plasters in ancient Egypt are reputed to be almost the same as those used today. However, some things have changed and a modern form of plastering called dry lining is becoming popular. This involves fixing internal plasterboard or wall board partitions to frames ready for decorating.
