I saw a youtube video about a 3 man crew hanging 4x20 ft gwb on the ceiling. I was a little surprised and the small number of screws they used, unless they went back and added more later. It did look like one guy was adding daubs of something on the framing just before the gwb was lifted. Commercial job, metal framing. Question ... if they were using adhesive does that change the screw pattern?
