Final answer:
When using glue for drywall, screws should be placed 8 to 12 inches apart along the edges and every 16 or 12 inches in the field, depending on the stud spacing. Nails should be spaced about 7 inches apart along the edges and 12 inches apart in the field to hold the drywall in place until the glue sets.
Step-by-step explanation:
When drywalling using adhesive or glue, it is recommended to support the drywall sheets with nails or screws. Screws should be placed along the edges of the drywall sheets, generally spaced about 8 to 12 inches apart. It's important to place screws in the field of the drywall sheet (the large, flat area) at least every 16 inches if studs are placed 16 inches on center, or every 12 inches if studs are placed 24 inches on center. Nails can also be used and should be spaced about 7 inches apart along the edges and 12 inches apart on the field. The purpose of the screws or nails is to hold the drywall in place until the glue cures.
