All In One

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:

• Set the forms that hold concrete in place
• Install reinforcing rebar or mesh wire to strengthen the concrete
• Signal truck drivers to facilitate the pouring of concrete
• Spread, level, and smooth concrete, using a trowel, float, or screed
• Mold expansion joints and edges
• Monitor curing (hardening) to ensure a durable, smooth, and uniform finish
• Apply sealants or waterproofing to protect concrete

Terrazzo workers typically do the following (in addition to what cement masons do):

• Measure ingredients for terrazzo
• Blend a marble chip mixture that may have colors in it 
• Grind and polish surfaces for a smooth, lustrous look

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.

Craft and fine artists use a variety of materials and techniques to create art for sale and exhibition. Craft artists create handmade objects, such as pottery, glassware, textiles or other objects that are designed to be functional. Fine artists, including painters, sculptors, and illustrators, create original works of art for their aesthetic value, rather than a functional one.

Craft and fine artists typically do the following:

• Use techniques such as knitting, weaving, glass blowing, painting, drawing, or sculpting
• Develop creative ideas or new methods for making art
• Create sketches, templates, or models to guide their work
• Select which materials to use on the basis of color, texture, strength, and other qualities
• Process materials, often by shaping, joining, or cutting
• Use visual elements, such as composition, color, space, and perspective, to produce desired artistic effects
• Develop portfolios highlighting their artistic styles and abilities to show to gallery owners and others interested in their work

Artists create objects that are beautiful or thought-provoking. They often strive to communicate ideas or feelings through their art.

Craft artists make a wide variety of objects, mostly by hand, to sell in their own studios, online, in stores, or at arts-and-crafts shows. Some craft artists display their works in galleries and museums.

Craft artists work with many different materials, including ceramics, glass, textiles, wood, metal, and paper, to create unique pieces of art, such as pottery, quilts, stained glass, furniture, jewelry, and clothing. Many craft artists also use fine-art techniques--for example, painting, sketching, and printing--to add finishing touches to their products.

Fine artists typically display their work in museums, commercial or non-profit art galleries, corporate collections, and private homes. Some of their artwork may be commissioned (requested by a client), but most is sold by the artist or through private art galleries or dealers. The gallery and the artist decide in advance how much of the sale proceeds each will keep.

Some craft and fine artists spend much time and effort selling their artwork to potential customers or clients and building a reputation. However, only the most successful artists are able to support themselves solely through the sale of their works. Many artists have at least one other job to support their craft or art careers.

Some artists work in museums or art galleries as arts directors or as curators, planning and setting up exhibits. Others teach craft or art classes or conduct workshops in schools or in their own studios. For more information on workers who teach art classes, see the profiles on kindergarten and elementary school teachers, middle school teachers, high school teachers, postsecondary teachers, and self-enrichment teachers.

Craft and fine artists specialize in one or more types of art. The following are examples of types of craft and fine artists:

Cartoonists draw political, advertising, comic, and sports cartoons. Some cartoonists work with others who create the idea or story and write captions. Some create plots and write captions themselves. Most cartoonists have comic, critical, or dramatic talents in addition to drawing skills.

Ceramic artists shape, form, and mold artworks out of clay, often using a potter's wheel and other tools. They glaze and fire pieces in kilns, which are special furnaces that dry and harden the clay.

Fiber artists use fabric, yarn, or other natural and synthetic fibers to weave, knit, crochet, or sew textile art. They may use a loom to weave fabric, needles to knit or crochet yarn, or a sewing machine to join pieces of fabric for quilts or other handicrafts.

Fine art painters paint landscapes, portraits, and other subjects in a variety of styles, ranging from realistic to abstract. They may use one or more media, such as watercolors, oil paints, or acrylics.

Furniture makers cut, sand, join, and finish wood and other materials to make handcrafted furniture. For more information about other workers who assemble wood furniture, see the profile on woodworkers.

Glass artists process glass in a variety of ways--such as by blowing, shaping, or joining it--to create artistic pieces. Specific processes used include glassblowing, lampworking, and stained glass. These workers also decorate glass objects, such as by etching or painting.

Illustrators create pictures for books, magazines, and other publications, and for commercial products, such as textiles, wrapping paper, stationery, greeting cards, and calendars. Increasingly, illustrators use computers in their work. They might draw in pen and pencil and then scan the image into a computer to be colored in, or use a special pen to draw images directly onto the computer.

Sketch artists, a particular type of illustrator, often create likenesses of subjects with pencil, charcoal, or pastels. Sketches are used by law enforcement agencies to help identify suspects, by the news media to show courtroom scenes, and by individual customers for their own enjoyment.

Jewelry artists use metals, stones, beads, and other materials to make objects for personal adornment, such as earrings or bracelets. For more information about other workers who create jewelry, see the profile on jewelers and precious stone and metal workers.

Medical and scientific illustrators combine drawing skills with knowledge of biology or other sciences. Medical illustrators work with computers or with pen and paper to create images of human anatomy and surgical procedures, as well as three-dimensional models and animations. Scientific illustrators draw animal and plant life, atomic and molecular structures, and geologic and planetary formations. These illustrations are used in medical and scientific publications and in audiovisual presentations for teaching purposes. Some medical and scientific illustrators work for lawyers, producing exhibits for court cases.

Printmakers create images on a silk screen, woodblock, lithography stone, metal etching plate, or other type of matrix. The matrix is then inked and transferred to a piece of paper using a printing press or hand press to create the final work of art. Workers who do photoengraving are called printing workers. For more information, see the profile on printing workers.

Sculptors design three-dimensional works of art, either by molding and joining materials such as clay, glass, plastic, or metal, or by cutting and carving forms from a block of plaster, wood, or stone. Some sculptors combine various materials to create mixed-media installations. For example, some incorporate light, sound, and motion into their works.

Janitors and building cleaners keep many types of buildings clean, orderly, and in good condition.

Janitors and building cleaners typically do the following:

• Gather and empty trash and trash bins
• Clean building floors by sweeping, mopping, or vacuuming them
• Clean bathrooms and stock them with soap, toilet paper, and other supplies
• Keep buildings secure by locking doors
• Clean spills and other hazards using sponges and squeegees
• Wash windows, walls, and glass
• Order cleaning supplies
• Make minor repairs to the building, such as changing light bulbs
• Notify managers when the building needs major repairs

Janitors and building cleaning workers keep office buildings, schools, hospitals, retail stores, hotels, and other places clean, sanitary, and in good condition. Some do only cleaning, while others have a wide range of duties.

In addition to keeping the inside of buildings clean and orderly, some janitors and building cleaners work outdoors, mowing lawns, sweeping walkways, or shoveling snow. Some janitors also monitor the heating and cooling system, ensuring that it functions properly.

Janitors and building cleaners use many tools and equipment. Simple cleaning tools may include mops, brooms, rakes, and shovels. Other tools may include snowblowers and floor buffers.

Some janitors may be responsible for repairing small problems with electricity or plumbing, such as leaky faucets.

Tile and marble setters apply hard tile, marble, and wood tiles to walls, floors, and other surfaces.

Tile and marble setters typically do the following:

• Clean and level the surface to be tiled
• Measure and cut tile and marble
• Arrange tiles according to the design plans
• Prepare and apply mortar or other adhesives
• Install tile and marble in the planned area
• Apply grout with a rubber trowel
• Wipe off excess grout and apply necessary finishes, such as sealants

Tile installers, tilesetters, and marble setters install materials on a variety of surfaces, such as floors, walls, ceilings, countertops, patios, and roof decks. Because tile and marble must be set on smooth, even surfaces, installers often must level the surface to be tiled with a layer of mortar or plywood. If the area to be tiled is unstable, workers must nail a support of metal mesh or tile backer board to create a stable surface.

To cut tiles, workers use power wet saws, tile scribes, or hand-held tile cutters to create even edges. They use trowels of different sizes to spread mortar or a sticky paste, called mastic, evenly on the surface to be tiled. To minimize imperfections and keep rows straight and even, they put spacers between tiles. The spacers keep tiles the same distance from each other until the mortar is dry. After the mortar dries and the tiles are set, they apply grout between tiles using a rubber trowel (called a float).

Marble setters may cut marble to a specified size with a power wet saw. After putting the marble in place, marble setters polish the marble to a high luster, using power or hand sanders.

Upholsterers make, replace, and repair coverings on furniture and in vehicles.

Upholsterers typically do the following:

• Consult with clients to discuss alterations to the furniture and to help customers choose fabric
• Estimate costs for the project, including approximate fabric and labor costs
• Inspect furniture to find needed repairs in the frame, upholstery, and springs
• Remove and replace old and worn padding, filling, and broken springs
• Measure, cut, and sew fabric, and attach it to the furniture frame with tacks, staples and glue

Upholsterers put on covering and cushions to create new furniture and update old furniture and vehicle interiors. Although some upholsterers specialize in either working with old furniture or creating new furniture, most do both.

Upholsterers need to stay current with trends in furniture design and styles. They help choose fabrics that meet their customer's lifestyle, preferences, and needs. For example, upholsterers may help a client who has young children choose a long-lasting and durable fabric for a family room sofa that matches other furniture.

Sometimes they have to choose fabrics that meet building codes--such as being fire resistant--or fabrics that reflect the style of the building. They also may work with interior designers and architects who need furniture for a new building. For more information, see the profiles on interior designers and architects.

Upholsterers may specialize in working on cars and other vehicles. These workers create and replace upholstery for the interiors of cars and other vehicles. They upholster seats, carpet floors, and cover door panels. To replace interiors with another fabric or other material, such as leather, these workers first remove the seats from the vehicle before replacing the upholstery.

Some upholsterers own their business. In these cases, they may do management and administrative tasks, such as managing the finances of their business and taking orders.
