Drywall Construction Techniques Quiz

Safety Note - Handling Track

• Sharp metal track edges pose a serious injury hazard
• Treated as a potential site of infection
• Incorrectly grounded electrical tools can cause severe shock
• Loss of balance and falls from ladders or scaffolding are common accidents in drywall construction

Installing Ceiling Track

• Install ceiling track exactly above existing floor track
• Use plumb bob and snap line to ensure accuracy
• Space fasteners no more than 24 inches apart, unless local building standards require 16 inches
• Mark floor or track for stud positions before erecting backing studs

Installing Studs

• Install studs vertically on 24-inch centers
• Studs are held in place by track flanges
• Fasten studs using spot welding, crimping, or sheet-metal screws at required intervals
• Position studs for doors, windows, and partition corners
• Backing studs should be placed at inside corners of partitions

Headers and Cripple Studs

• Headers are cut to desired length, 8 inches longer than opening width
• Track flanges are cut 4 inches in from each end, bent at 90°
• Position header between door bucks, enclosing studs on sides
• Cripple studs are located along wallboard joints
• Fasten using drywall screws

Splicing Studs

• Metal studs can be spliced when necessary
• Lap portions are fastened using four drywall screws
• Door bucks, window wells, and headers have web side facing opening

Wallboard Application

• Apply gypsum wallboard horizontally in most cases
• Ensure all edges and end joints are located in the center of stud flanges
• Limit end joints to reduce their overall number
• Install outlets and services prior to wallboard erection
