Painters apply paint, stain, and coatings to walls, buildings, bridges, and other structures.
Painters typically do the following:
Applying paint to interior walls makes surfaces attractive and vibrant. In addition, paints and other sealers protect exterior surfaces from erosion caused by exposure to the weather.
Because there are several ways to apply paint, workers must be able to choose the proper tool for each job, such as the correct roller, power sprayer, and the right size brush. Choosing the right tool typically depends on the surface to be covered and the characteristics of the finish.
A few painters--mainly industrial--must use special safety equipment. For example, painting in confined spaces such as the inside of a large storage tank, requires workers to wear self-contained suits to avoid inhaling toxic fumes. When painting bridges, tall buildings, or oil rigs, painters may work from scaffolding, bosun's chairs, and harnesses to reach work areas.
The following are examples of types of painters:
Construction painters apply paints, stains, and coatings to interior and exterior walls, new buildings, and other structural surfaces.
Maintenance painters remove old finishes and apply paints, stains, and coatings later in a structure's life. Some painters specialize in painting or coating industrial structures, such as bridges and oil rigs, to prevent corrosion.
Artisan painters specialize in creating distinct finishes by using one of many decorative techniques. One technique is adding glaze for added depth and texture. Other common techniques may include sponging, distressing, rag-rolling, color blocking, and faux finishes.
Painting and coating workers apply materials to manufactured products, such as furniture, toys and pottery, as well as transportation equipment including trucks, buses, boats, and airplanes. For more information about these painters, see the profile on painting and coating workers.
Construction and building inspectors ensure that new construction, changes, or repairs comply with local and national building codes and ordinances, zoning regulations, and contract specifications.
Construction and building inspectors typically do the following:
Construction and building inspectors examine buildings, highways and streets, sewer and water systems, dams, bridges, and other structures. They also inspect electrical; heating, ventilation, air-conditioning, and refrigeration (HVACR); and plumbing systems. Although no two inspections are alike, inspectors do an initial check during the first phase of construction and follow-up inspections throughout the construction project. When the project is finished, they do a final, comprehensive inspection.
The following are types of construction and building inspectors:
Building inspectors check the structural quality and general safety of buildings. Some specialize in structural steel or reinforced-concrete structures, for example.
Electrical inspectors examine the installed electrical systems to ensure they function properly and comply with electrical codes and standards. The inspectors visit worksites to inspect new and existing sound and security systems, wiring, lighting, motors, and generating equipment. They also inspect the installed electrical wiring for HVACR systems and appliances.
Elevator inspectors examine lifting and conveying devices, such as elevators, escalators, moving sidewalks, lifts and hoists, inclined railways, ski lifts, and amusement rides.
Home inspectors typically inspect newly built or previously owned homes, condominiums, townhomes, and other dwellings. Prospective home buyers often hire home inspectors to check and report on a home's structure and overall condition. Sometimes, homeowners hire a home inspector to evaluate their home's condition before placing it on the market.
In addition to examining structural quality, home inspectors examine all home systems and features, including roofing, exterior walls, attached garage or carport, foundation, interior, plumbing, electrical, and HVACR systems. They look for and report violations of building codes, but they do not have the power to enforce compliance with the codes.
Mechanical inspectors examine the installation of HVACR systems and equipment to ensure that they are installed and function properly. They also may inspect commercial kitchen equipment, gas-fired appliances, and boilers.
Plan examiners determine whether the plans for a building or other structure comply with building codes. They also determine whether the structure is suited to the engineering and environmental demands of the building site.
Plumbing inspectors examine the installation of potable water, waste, and vent piping systems to ensure the safety and health of the drinking water system, piping for industrial uses, and the sanitary disposal of waste.
Public works inspectors ensure that federal, state, and local government water and sewer systems, highways, streets, bridges, and dam construction conform to detailed contract specifications. Workers inspect excavation and fill operations, the placement of forms for concrete, concrete mixing and pouring, asphalt paving, and grading operations. Public works inspectors may specialize in highways, structural steel, reinforced concrete, or ditches. Others specialize in dredging operations required for bridges and dams or for harbors.
Specification inspectors ensure that work is performed according to design specifications. Specification inspectors represent the owner's interests, not those of the general public. Insurance companies and financial institutions also may use their services.
A primary concern of building inspectors is fire prevention safety. For more information, see the profile on fire inspectors and investigators.
Carpet installers lay carpet in homes, offices, restaurants, and many other types of buildings.
Carpet installers typically do the following:
Carpet installers lay carpet in many types of new and old buildings, including homes, offices, restaurants, and museums. Although installing carpet in newly constructed buildings requires minimal preparation, those who replace existing carpet must first remove old flooring, including any padding, glue, tacks, or staples. In some cases, carpet installers lay carpet over existing tile or hardwood.
Carpet installers work with special tools, including a "knee kicker" to position the carpet and a power stretcher to pull the carpet snugly against walls. When they have to join seams of carpet (for example, in large rooms), they use special heat-activated tape. In commercial installations, they may glue the carpet to the floor or to padding that they have glued to the floor. On steps, they may use staples to hold the carpet in place. They also use carpet knives, carpet shears (scissors), hammers, power sanders, and other tools.
Cement masons pour, smooth, and finish concrete floors, sidewalks, roads, and curbs. Using a cement mixture, terrazzo workers create durable and decorative surfaces for floors and stairways.
Cement masons typically do the following:
Terrazzo workers typically do the following (in addition to what cement masons do):
Concrete is one of the most common and durable materials used in construction. Once set, concrete--a mixture of cement, sand, gravel, and water--becomes the foundation for everything from decorative patios and floors to huge dams or miles of roadways.
The following are types of cement masons and terrazzo workers:
Cement masons and concrete finishers place and finish concrete. They may color concrete surfaces, expose aggregate (small stones) in walls and sidewalks, or make concrete beams, columns, and panels.
Throughout the process of pouring, leveling, and finishing concrete, cement masons must monitor how the wind, heat, or cold affects the curing of the concrete. They must have a thorough knowledge of the characteristics of concrete so that, by using sight and touch, they can determine what is happening to the concrete and take measures to prevent defects.
Terrazzo workers and finishers create decorative walkways, floors, patios, and panels. Although much of the preliminary work in pouring, leveling, and finishing concrete is similar to that of cement masons, terrazzo workers create more decorative finishes by blending a fine marble chip into the cement, which is often colored. Once the terrazzo is thoroughly set, workers correct any depressions or imperfections with a grinder to create a smooth, uniform finish.
Painting and coating workers paint and coat a wide range of products, including cars, jewelry, and candy.
Painting and coating workers typically do the following:
Millions of items ranging from cars to candy are covered by paint, plastic, varnish, chocolate, or some other type of coating. Painting or coating is used to make a product more attractive or protect it from the elements. The paint finish on an automobile, for example, makes the vehicle more attractive and provides protection from corrosion.
Before workers begin to apply the paint or other coating, they often need to prepare the surface by sanding or cleaning it carefully to prevent dust from becoming trapped under the paint. Sometimes, masking is required, which involves carefully covering portions of the product with tape and paper.
After the product is prepared, workers may use a number of techniques to apply the paint or coating. Perhaps the most straightforward technique is dipping an item in a large vat of paint or some other coating. Spraying products with a solution of paint or another coating is also common. Some factories use automated painting systems.
The following are types of painting and coating workers:
Dippers use power hoists to immerse products in vats of paint, liquid plastic, or other solutions. This technique is commonly used for small parts in electronic equipment, such as cell phones.
Spray machine operators use spray guns to coat metal, wood, ceramic, fabric, paper, and food products with paint and other coating solutions.
Coating, painting, and spraying machine setters, operators, and tenders position the spray guns, set the nozzles, and synchronize the action of the guns with the speed of the conveyor carrying products through the machine and through drying ovens. During the operation of the painting machines, these workers tend the equipment, watch gauges on the control panel, and check products to ensure that they are being painted evenly. The operator may use a manual spray gun to “touch up” flaws.
Painting, coating, and decorating workers paint, coat, or decorate products such as furniture, glass, pottery, toys, cakes, and books. Some workers coat confectionery, bakery, and other food products with melted chocolate, cheese, oils, sugar, or other substances. Paper is often coated to give it its gloss. Silver, tin, and copper solutions are frequently sprayed on glass to make mirrors.
Transportation equipment painters are the best known group of painting and coating workers. There are three major specialties:
<p style=" margin-left: 20.0px;">Transportation equipment workers who refinish old or damaged cars, trucks, and buses in automotive body repair and paint shops normally apply paint by hand with a controlled spray gun. Those who work in repair shops are among the most highly skilled manual spray operators: They perform intricate, detailed work and mix paints to match the original color, a task that is especially difficult if the color has faded. Preparing an old car is similar to painting other metal objects.<p style=" margin-left: 20.0px;">Transportation equipment painters who work on new cars oversee several automated steps. A modern car is first dipped in an anticorrosion bath, coated with colored paint, and then painted in several coats of clear paint to prevent damage to the colored paint.<p style=" margin-left: 20.0px;">Other transportation equipment painters either paint equipment too large to paint automatically--such as ships or giant construction equipment--or do touchup work to fix flaws in the paint caused by damage either during assembly or during the automated painting process.
