- Always start by making a sketch of the wall and ceiling areas to be covered before applying the drywall. A sketch enables you to detect errors on paper-not on the job.
- Always install the wallboards perpendicular to (across) the joists on ceilings.
- You should apply drywall to the ceiling first, then to the walls.
- Use a special water-resistant drywall where excessive moisture may be a problem. In most cases, water-resistant drywall is covered with a green finish paper.
- Install a special fire-rated drywall where building codes require the use of a fire-rated material.
- If a vapor barrier is needed, use a special insulating, foil-backed wallboard, or create a vapor barrier with sheets of plastic material.
Preparation is the key...
Taping the drywall on a ceiling can be very tricky.
