Nature of the Work

Drywall and ceiling tile installers, tapers, plasterers, and stucco masons are specialty construction workers who build, apply, or fasten interior and exterior wallboards or wall coverings in residential, commercial, and other structures. Specifically, drywall and ceiling tile installers and tapers work indoors, installing wallboards to ceilings or to interior walls of buildings; plasterers and stucco masons, on the other hand, work both indoors and outdoors-applying plaster to interior walls and cement or stucco to exterior walls. While most work is performed for functionality, such as fireproofing and sound dampening, some applications are intended purely for decorative purposes.

Plasterers apply plaster to interior walls and ceilings to form fire-resistant and relatively soundproof surfaces. They also apply plaster veneer over drywall to create smooth or textured abrasion-resistant finishes. In addition, plasterers install prefabricated exterior insulation systems over existing walls-for good insulation and interesting architectural effects-and cast ornamental designs in plaster. Stucco masons apply durable plasters, such as polymer-based acrylic finishes and stucco, to exterior surfaces.

Plasterers can plaster either solid surfaces, such as concrete block, or supportive wire mesh called lath. When plasterers work with hard interior surfaces, such as concrete block and concrete, they first apply a brown coat of gypsum plaster that provides a base, which is followed by a second, or finish coat, also called "white coat." When plastering metal-mesh lath foundations, they apply a preparatory, or "scratch coat" with a trowel. They spread this rich plaster mixture into and over the metal lath. Before the plaster sets, plasterers scratch its surface with a rake-like tool to produce ridges, so that the subsequent brown coat will bond tightly. They then apply the brown coat and the white finish coat.

When plastering on non-solid surfaces, lathers are needed to help build supportive walls out of wire. This support base is put on walls, ceilings, ornamental frameworks, and partitions of buildings before plaster and other coatings are added.

Applying different types of plaster coating requires different techniques. When applying the brown coat, plasterers spray or trowel the mixture onto the surface, then smooth it to an even, level surface. For the finish, or white coat, plasterers usually prepare a mixture of plaster and water. They quickly apply this using a "hawk," that is a light, metal plate with a handle, along with a trowel, brush, and water. This mixture, which sets very quickly, produces a very smooth, durable finish.

Plasterers create decorative interior surfaces as well. One way that they do this is by pressing a brush or trowel firmly against a wet plaster surface and using a circular hand motion to create decorative swirls. Plasterers sometimes do more complex decorative and ornamental work that requires special skill and creativity. For example, they may mold intricate wall and ceiling designs, such as cornice pieces and chair rails. Following an architect's blueprint, plasterers pour or spray a special plaster into a mold and allow it to set. Workers then remove the molded plaster and put it in place, according to the plan.

Stucco masons usually apply stucco-a mixture of Portland cement, lime, and sand-over cement, concrete, masonry or wire lath. Stucco also may be applied directly to a wire lath with a scratch coat, followed by a brown coat, and then a finish coat. Stucco masons may also embed marble or gravel chips into the finish coat to achieve a pebble-like, decorative finish.

When required, stucco masons apply insulation to the exteriors of new and old buildings. They cover the outer wall with rigid foam insulation board and reinforcing mesh, and then trowel on a base coat. They may apply an additional coat of this material with a decorative finish.

Work environment. As in many other construction trades, this work is physically demanding. Plasterers and stucco masons spend most of the day on their feet, either standing, bending, stretching, or kneeling. Some workers need to use stilts; others may have to lift and maneuver heavy, cumbersome materials, such as oversized wallboards. The work also can be dusty and dirty, irritating the skin, eyes, and lungs, unless protective masks, goggles, and gloves are used. Hazards include falls from ladders and scaffolds, and injuries from power tools and from working with sharp tools, such as utility knives.

Most work indoors, except for the relatively few stucco masons who apply exterior finishes.

Training, Other Qualifications, and Advancement

Most workers learn their trade through informal training programs or through an apprenticeship. It can take 3 to 4 years of paid on-the-job training to become a fully skilled worker, but many skills can be learned within the first year. In general, the more formal the training process, the more skilled the individual becomes, and the more in demand by employers.

Education and training. A high school education, or its equivalent, is helpful, as are courses basic math, mechanical drawing, and blueprint reading. The most common way to get a first job is to find an employer who will provide on-the-job training. Entry-level workers generally start as helpers, assisting more experienced workers. Employers may also send new employees to a trade or vocational school or community college to receive classroom training.

Some employers, particularly large nonresidential construction contractors with unionized workforces, offer employees formal apprenticeships. These programs combine on-the-job training with related classroom instruction-at least 166 hours for plasterers and stucco masons. The length of the apprenticeship program, usually 3 to 4 years, varies with the apprentice's skill. Because the number of apprenticeship programs is limited, however, only a small proportion of these workers learn their trade this way.

Helpers and apprentices start by carrying materials, lifting and cleaning up debris. They also learn to use the tools, machines, equipment, and materials of the trade. Within a few weeks, they learn to measure, cut, apply, and install materials. Eventually, they become fully experienced workers. At the end of their training, workers learn to estimate the cost of completing a job.

Other jobseekers may choose to obtain their training before seeking a job. There are a number of vocational-technical schools and training academies affiliated with the industry's unions and contractors that offer training in these occupations. Employers often look favorably upon graduates of these training programs and usually start them at a higher level than those without the training.

Other qualifications. Workers need to be in good physical condition and have good eye-hand coordination, a sense of balance and manual dexterity. Artistic creativity is helpful for plasterers and stucco masons who apply decorative finishes. In addition, a good work history is viewed favorably by contractors.

Apprentices usually must be at least 18 years old and have a high school diploma or GED. Those who complete apprenticeships registered with the Federal or State Government receive a journey worker certificate that is recognized Nationwide.

Certification and advancement. Some organizations related to masonry trades offer training and certification intended to enhance the skills of their members. For example, the International Union of Bricklayers and Allied Craftworkers International Masonry Institute confers designations in several areas of specialization, including one for plastering. Candidates who complete a 12-week certification program can earn a designation as a "journey level plasterer" by passing a competency-based exam. Experienced candidates can become trainers and earn a designation as "Certified Instructor or Journeyworkers and Apprentices in the Trowel Trades."

Plasterers and stucco masons may advance to supervisor or general construction supervisor positions. However, it is increasingly important to be able to communicate in both English and Spanish in order to relay instructions and safety precautions to workers with limited understanding of English because Spanish-speaking workers make up a large part of the construction workforce in many areas. Knowing English well also makes it easier to advance. Many workers become independent contractors. Others become building inspectors.

Job Outlook

Employment of drywall and ceiling tile installers, tapers, plasterers, and stucco masons is expected to grow about as fast as average for all occupations. Job growth, however, will differ among the individual occupations in this category. Good job prospects are expected overall.

Employment change. Employment of plasterers and stucco masons, on the other hand, is expected to grow 7 percent. Despite an increased appreciation for the attractiveness and durability that plaster provides, growing use of cheaper and easier to install alternatives, such as drywall, will impede employment growth for these workers. Nonetheless, stucco masons will experience some employment growth due to demand for new polymer-based exterior insulating finishes that are gaining popularity, particularly in the South and Southwest regions of the country.

Job prospects. Job opportunities for plasterers and stucco masons are expected to be good overall. Many potential workers are not attracted to this occupation because they prefer work that is less strenuous and has more comfortable working conditions. Experienced workers will have especially favorable opportunities.

Skilled, experienced plasterers with artistic ability should have excellent opportunities, especially with restoration projects. Decorative custom finishes, expensive homes, and large-scale restoration projects will further result in opportunities for plasterers in the Northeast, particularly in urban areas. For stucco masons, the best employment opportunities should continue to be in Florida, California, and the Southwest, where the use of stucco is expected to remain popular.

Like many other construction workers, employment in these occupations is sensitive to the fluctuations of the economy. Workers in these trades may experience periods of unemployment when the overall level of construction falls. On the other hand, shortages of these workers may occur in some areas during peak periods of building activity.
