What is Construction Drywall and Ceiling Tile Installers Job Description ?
Drywall consists of a thin layer of gypsum between two layers of heavy paper. It is used to make walls and ceilings in most buildings today because it is faster and cheaper to install than plaster.
There are two kinds of drywall workersinstallers and tapersalthough many workers do both types of work. Installers, also called framers or hangers, fasten drywall panels to the inside framework of houses and other buildings. Tapers or finishers, prepare these panels for painting by taping and finishing joints and imperfections. In addition to drywall workers, ceiling tile installers and lathers also help to build walls and ceilings.
Because drywall panels are manufactured in standard sizesusually 4 feet by 8 or 12 feetdrywall installers must measure, cut, fit, and fasten them to the inside framework of buildings. Workers cut smaller pieces to go around doors and windows. Installers saw, drill, 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, called studs. Because drywall is heavy and cumbersome, another worker usually helps the installer to position and secure the panel. Installers often use a lift when placing ceiling panels.
After the drywall is installed, tapers fill joints between panels with a joint compound, also called spackle or "mud." Using the wide, flat tip of a special trowel, they spread the compound into and along each side of the joint with brush-like strokes. They immediately use the trowel to press a paper tapeused to reinforce the drywall and to hide imperfectionsinto the wet compound and to smooth away excess material. Nail and screw depressions also are covered with this compound, as are imperfections caused by the installation of air-conditioning vents and other fixtures. On large projects, finishers may use automatic taping tools that apply the joint compound and tape in one step. Using increasingly wider trowels, tapers apply second and third coats of the compound, sanding the treated areas after each coat to make them as smooth as the rest of the wall surface. This results in a seamless and almost perfect surface. For hard to reach heights and ceilings, sanding poles are commonly used. Some tapers apply textured surfaces to walls and ceilings with trowels, brushes, or spray guns.
Ceiling tile installers, or acoustical carpenters, apply or mount acoustical tiles or blocks, strips, or sheets of shock-absorbing materials to ceilings and walls of buildings to reduce reflection of sound or to decorate rooms. First, they measure and mark the surface according to blueprints and drawings. Then, they nail or screw moldings to the wall to support and seal the joint between the ceiling tile and the wall. Finally, they mount the tile, either by applying a cement adhesive to the back of the tile and then pressing the tile into place, or by nailing, screwing, stapling, or wire-tying the lath directly to the structural framework.
Making walls out of plaster requires the work of lathers. Lathers apply the support base for plaster coatings, fireproofing, or acoustical materials. This support base, called lath, is put on walls, ceilings, ornamental frameworks, and partitions of buildings before plaster and other coatings are added. Lathers use handtools and portable power tools, to nail, screw, staple, or wire-tie the lath directly to the structural framework of a building. At one time, lath was made of wooden strips, but now, it is usually made of wire, metal mesh, or gypsum, also known as rockboard. Metal lath is used when the plaster on top of it will be exposed to weather or water or when a surface is curved or irregular and not suitable for drywall.
