Carpenters   Local    1715   Exterior /Interior

The work of the interior/exterior specialist includes drywall, acoustical ceilings, metal framing, raised floors and lathing systems. Their specialized skills are brought into play as they assemble complex interior systems using technical data supplied by manufacturers. Interior systems carpenters generally need carpentry tools such as saws and hammers as well as mechanic's tools such as drills, wrenches and screwdrivers. They also use their welding skills to do some assembly work.

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.

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.

Because drywall panels are manufactured in standard sizes—usually 4 feet by 8 or 12 feet—installers must measure, cut, and fit some pieces around doors and windows. They also saw or cut holes in panels for electrical outlets, air-conditioning units, and plumbing. After making these alterations, installers may glue, nail, or screw the wallboard panels to the wood or metal framework. Because drywall is heavy and cumbersome, a helper generally assists the installer in positioning and securing the panel. A lift is often used when placing ceiling panels.

As in many other construction trades, drywall work sometimes is strenuous. Installers and finishers spend most of the day on their feet, either standing, bending, or kneeling. Some finishers use stilts to tape and finish ceiling and angle joints. Installers have to lift and maneuver heavy panels. Hazards include falls from ladders and scaffolds, and injuries from power tools. Because sanding joint compound to a smooth finish creates a great deal of dust, some finishers wear masks for protection.
