After insulation installation is completed and inspected, drywall installation and finish begins.
Large boom trucks pull up on your lot and hoist sheetrock through an upstairs window designed to open and allow this process to take place (both sashes are designed for removal). Specialty sheetrock designed to repel moisture will line the bathroom areas, and the rest of your rooms will take shape with the hanging of the sheetrock. The majority of the sheetrock in your new home will be ½” thick, on both walls and ceilings.
Building codes do require some walls use a fire resistant sheetrock which will be 5/8” thick. The walls in a garage that are common to living areas should be covered with 5/8” thick sheetrock.
Sheetrock hung with screws requires a maximum spacing of 12” between screws, while sheetrock hung with nails requires a maximum spacing of 7” between nails on ceilings, and a maximum spacing of 8” on walls. As a home dries and settles, nails can back out causing “nail pops” and necessitating repairs. I strongly urge you to require screws of the proper length be used to hang all of the sheetrock in your new home.
Properly hung sheetrock will have the joints staggered so that they do not line up over the top of each other. Much like a brick pattern, you should see joints staggered over the walls. Note that sheetrock comes in different lengths and widths. To minimize waste, sheetrock should be ordered as close to the size of a room as possible. A very simple example follows – your room is 12’ x 12’ with a 9’ ceiling, so two sheets 54-1/2” x 12’ will cover one wall without waste. In a perfect world, all of your rooms would be sized to minimize sheetrock waste. If your General Contractor is on site, minimizing waste should not be an issue.
Upon the completion of hanging, the taping and floating process begins. Specialty paper tape is applied over all joints in a generous bed of sheetrock mud. The excess mud blends the edge of the tape into the wall surface and create a smooth wall. After the initial coat of mud dries, an additional coat is applied, allowed to dry, and then sanded to a smooth finish.
Years of experience have shown me that the majority of repairs, required after a final walk-thru on your completed home, emanate from drywall repairs. Following the application of the prime coat of paint, shine a bright light over all drywall surfaces, identify, and repair imperfections before the final coat of paint. This is important because repairs and paint touchup will never blend as well as a full coat of paint on your wall.
Upon completion, the plywood subfloors in your home need a good cleaning to scrape up and remove excess mud, and you are ready to begin tile and hardwood flooring.
