When you are installing drywall in a room, always start with the ceiling. The reason for this is that the drywall sheets on the sidewalls will be supporting the edges of the ceiling drywall sheets, so it is much easier to install the ceiling first. The ceiling is also usually the hardest area to cover, and this way you get the worst part over with right away.
Step One: is to choose which way to place the long dimension of the wallboards. It is recommended to run the length of the sheet perpendicular to the ceiling joists. It will reduce the chance of joint cracks or nail pops appearing, as well as give maximum structural strength to the drywall installation.
Depending on the length of drywall sheet you are using, and the orientation of the ceiling joists relative to the shape of the room, you should also consider placing the length of the sheets such that you have a minimum number of joints to between sheets to finish.
When installing drywall on a ceiling, the sheets should be both double-nailed and glued in place. Use drywall and construction adhesive, available in 11 and 29-ounce caulking gun cartridges. The 11 ounce size is easier to use and holds enough for drywalling jobs.
Due to the weight of the wallboard exerting a downward pull on the nails, there is greater risk of nail pops and joint cracks, but this attachment method will greatly reduce these chances. Cracks and other flaws in ceiling joints are usually much more noticeable than in sidewalls because of the lighting fixtures.
Step Two: Start covering the ceiling in one of the corners, and try to begin with a full sheet. For applying the glue, use a caulking gun, cutting the tip of the glue cartridge at and angle of 45 degrees. On joists located in the center portion of a wallboard, apply a single bead line of glue straight down the middle of the joist. On the joists at the joint edges of the wallboard, apply the glue in a single bead line zig-zag, or snake pattern.
Step Three: Nailing Warning- Wear protective eyewear, you will be nailing overhead and debris may fall. In fact, gypsum wallboard dust is non-toxic, but will cause your eyes to burn and keep you from working for a minute or so. Try not to stand directly under the nail you are working on; this will help.
It is recommended to use a drywalling hammer. This is a special purpose tool which has a rounded head, used to create the dimpling in the wallboard around the nailhead. The face the head is serrated in a waffle-like pattern to grip the nailhead while nailing. Your nailing pattern should be:
– on the joint edges of the wallboard sheets, one row of nails six inches apart, an eigth of an inch from the edge
– On the long length edges, a row pitched 24 inches aaprt, 1/8 inch from the edge
– Along the joists, the pattern should be (for a 4″ wide sheet) one nail an eight inch from the edge, then a spacing of 24 inches, a row of double nailing spaced 2 inches aprt, then 24 inches to the next double nailing, and repeat.
– On butt joints, stagger the nails with a one inch offset
Step Four: Before you apply the joint tape and finish tot the ceiling, you will be installing the drywall on the walls.
Step Five: Proceed to the Joint Finishing of the ceiling.
