After the drywall panels are placed, the Tapers prepare the panels with tape by applying the tape to surfaces of walls and ceilings for painting. Drywall Installers and Tapers work with drywall, a construction building material which is often used in place of plaster for indoor walls and ceilings. Drywall is a thin section of plaster, sandwiched between two pieces of heavy paper, and is available in panels of standard sizes. Drywall Installers who belong to a union do either installation or finishing, but those workers who do not belong to a union usually work and have experience in all the phases of drywall work. A Drywall Installer must be able to measure and cut pieces of the drywall to fit spaces of the walls and ceilings like above and under windows.
Holes have to sawed in drywall panels for fitting vents, plumbing fixtures, and electrical outlets.
After making these adjustments, Installers nail panels to studs or beams, or screw panels into metal studs. Installers usually work with a partner to lift and install large drywall panels for ceilings. Installers usually hang drywall panels on metal framework in offices, schools, and other large buildings. Installers check plans for the location of rooms and hallways, then they cut and screw together metal channels to make floor and ceiling frames. The installers then screw the drywall panels to the framework.
