Drywall consists of a thin layer of gypsum between two layers of heavy
paper. It is used today for walls and ceilings in most buildings because
it is both faster and cheaper to install than plaster.
How is it Installed
There are two kinds of drywall workers: installers and finishers. Installers,
also called applicators, fasten drywall panels to the inside
framework of residential houses and other buildings. Finishers, or tapers,
prepare these panels for painting by taping and finishing joints and
imperfections.
