For a new drywall installation, what does the Selector Code "1/2" stand for?

The Selector Code "1/2" specifically refers to 1/2" drywall that has been hung, taped, and floated, making it ready for the painting process. This measurement indicates the thickness of the drywall panels, which is a common size used in residential construction for interior walls and ceilings. The phrase "hung, taped, and floated" describes the essential stages of drywall installation that prepare it for finishing touches such as painting.

In contrast, other thicknesses like 5/8" or 1/4" serve different purposes and are not the intended meaning of the "1/2" code. Standard drywall is a term that could describe various types of drywall, but it does not convey the specific status of being prepared for paint as highlighted by the correct choice. Therefore, the choice accurately encapsulates the type of drywall being referred to, along with the necessary preparation it has undergone.
