Which of the following is NOT an element found in a plastered wall section?

In the context of construction, particularly regarding plastered wall sections, the materials involved typically include a plaster base, plaster grounds, and plaster itself. The plaster base serves as a foundational layer that supports the finishing plaster. Plaster grounds are strips used to provide a straight edge or guide for applying the plaster, ensuring a uniform thickness.

The term “plaster board,” on the other hand, is not a component of a traditional plastered wall section. Plaster board, often known as drywall or gyprock, is a prefabricated building material used for constructing interior walls and ceilings. It is typically made of gypsum sandwiched between two sheets of heavy paper. While plaster board can be part of wall construction, it is distinct from the plastering process and materials utilized in creating a traditional plastered wall.

Understanding these definitions clarifies that when focusing on elements specifically associated with plastered walls, plaster board does not belong to that category, making it the correct choice in this question.
