Job Description

Carpet, tile, and other types of floor coverings not only serve an important basic function in buildings, but their decorative qualities also contribute to the appeal of the buildings. Carpet, floor, and tile installers and finishers lay floor coverings in homes, offices, hospitals, stores, restaurants, and many other types of buildings. Tile also may be installed on walls and ceilings.
Before installing carpet, carpet installers first inspect the surface to be covered to determine its condition and, if necessary, correct any imperfections that could show through the carpet or cause the carpet to wear unevenly. They measure the area to be carpeted and plan the layout, keeping in mind expected traffic patterns and placement of seams for best appearance and maximum wear.
When installing wall-to-wall carpet without tacks, installers first fasten a tackless strip to the floor, next to the wall. They then install the padded cushion or underlay. Next, they roll out, measure, mark, and cut the carpet, allowing for 2 to 3 inches of extra carpet for the final fitting. Using a device called a knee kicker, they position the carpet, stretching it to fit evenly on the floor and snugly against each wall and door threshold. They then cut off the excess carpet. Finally, using a power stretcher, they stretch the carpet, hooking it to the tackless strip to hold it in place. The installers then finish the edges using a wall trimmer.

Because most carpet comes in 12-foot widths, wall-to-wall installations require installers to join carpet sections together for large rooms. The installers join the sections using heat-taped seamsseams held together by a special plastic tape that is activated by heat.

On special upholstery work, such as stairs, carpet may be held in place with staples. Also, in commercial installations, carpet often is glued directly to the floor or to padding that has been glued to the floor.
Carpet installers use hand tools such as hammers, drills, staple guns, carpet knives, and rubber mallets. They also may use carpetlaying tools, such as carpet shears, knee kickers, wall trimmers, loop pile cutters, heat irons, and power stretchers.

Floor installers and floor layers lay floor coverings such as laminate, linoleum, vinyl, cork, and rubber for decorative purposes, or to deaden sounds, absorb shocks, or create air-tight environments. Although they also may install carpet, wood or tile, that is not their main job. Before installing the floor, floor layers inspect the surface to be covered and, if necessary, correct any deficiencies, such as a rotted or unleveled sub-floor, in order to start with a sturdy, smooth, clean foundation. They measure and cut floor covering materials. When installing linoleum or vinyl, they may use an adhesive to cement the material directly to the floor. For laminate floor installation, workers may unroll and install a polyethylene film which acts as a moisture barrier, along with a thicker, padded underlayer which helps reduce noise. Cork and rubber floors often can be installed directly on top of the sub-floor without any underlayer. Finally, floor layers install the floor covering to form a tight fit.

After a carpenter installs a new hardwood floor or when a customer wants to refinish an old wood floor, floor sanders and finishers are called in to smooth any imperfections in the wood and apply finish coats of varnish or polyurethane. To remove imperfections and smooth the surface, they will scrape and sand wooden floors using floor sanding machines. They then inspect the floor and remove excess glue from joints using a knife or wood chisel and may further sand the wood surfaces by hand, using sandpaper. Finally, they apply sealant using brushes or rollers, often applying multiple coats.

Tile installers, tilesetters, and marble setters apply hard tile and marble to floors, walls, ceilings, countertops, patios, and roof decks. Tile and marble are durable, impervious to water, and easy to clean, making them a popular building material in bathrooms, kitchens, hospitals, and commercial buildings.
Prior to installation, tilesetters use measuring devices and levels to ensure that the tile is placed in a consistent manner. Tile varies in color, shape, and size, ranging in size from 1 inch to 24 or more inches on a side, so tilesetters sometimes prearrange tiles on a dry floor according to the intended design. This allows them to examine the pattern, check that they have enough of each type of tile, and determine where they will have to cut tiles to fit the design in the available space. To cover all exposed areas, including corners and around pipes, tubs, and wash basins, tilesetters cut tiles to fit with a machine saw or a special cutting tool. To set tile on a flat, solid surface such as drywall, concrete, plaster, or wood, tilesetters first use a tooth-edged trowel to spread a thin set, or thin layer of cement adhesive or mastic, a very sticky paste. They then properly position the tile and gently tap the surface with their trowel handle, rubber mallet, or a small block of wood to set the tile evenly and firmly. Spacers are used to maintain exact distance between tiles, and any excess thin set is wiped off the tile immediately after placement.

To apply tile to an area that lacks a solid surface, tilesetters nail a support of metal mesh or tile backer board to the wall or ceiling to be tiled. They use a trowel to apply a cement mortarcalled a scratch coatonto the metal screen, and scratch the surface of the soft mortar with a small tool similar to a rake. After the scratch coat has dried, tilesetters apply a brown coat of mortar to level the surface, and then apply mortar to the brown coat and place tile onto the surface. Hard backer board also is used in areas where there is excess moisture, such as a shower stall.

When the cement or mastic has set, tilesetters fill the joints with grout, which is very fine cement and includes sand for joints 1/8th of an inch and larger. They then apply the grout to the surface with a rubber-edged device called a grout float or a grouting trowel to fill the joints and remove excess grout. Before the grout sets, they wipe the tiles and finish the joints with a damp sponge for a uniform appearance.

Marble setters cut and set marble slabs in floors and walls of buildings. They trim and cut marble to specified sizes using a power wet saw, other cutting equipment, or handtools. After setting the marble in place, they polish the marble to high luster using power tools or by hand.
