Many people start with walls, THIS IS WRONG. Start with the ceilings, this will give you tight corners when putting up the wall. Sheets should be hung in a horizontal fashion not vertical. There are the “Butt” joints, where the ends of the drywall meet, and the “Recess” joints where the edges meet. Because many cracks happen in corners and these need to stay tight. Sheets should be 12′ long and the “Butt” joints should not break along the same line. The white side if the sheet is to be face out.
Starting with the ceiling sheets should be nailed or screwed to the trusses and fasten at the end with the “butt” joints staggered. After the ceiling is hung, the top sheet on the wall needs to be next. Light switch boxes and window need to be cut out, flush to the box or window, with no gaps. Nails or screws should be ever 12 inches on top of the sheet, and nails or screws on the bottom of the sheet that fasten the sheet to the stud. The ends of the sheet, or the “butt joint” should have 7 nails or screws applied in each joint. Next the bottom sheets need to be installed in the same manner that the top sheet was hung, leaving no less that 3/4″ gap at the bottom where the sheet meets the floor, nailed or screwed ever 16″ at the bottom of the sheet.
After the sheetrock has been tacked to the walls and ceiling. Screws need to be put in the middle of the sheets along the studs and trusses. There should be a minimum of 3 screws per stud or truss for a 48″ sheet and 4 screws for a 54″ sheet. All corners should be tight and nailed with a minimum of 6 nails or screws in each corner. Nails or screws should not break the face of the drywall paper, but be set deep enough that they should not show when taped. When your sheetrock is applied correctly you can bang on the sheet lightly with your hand and the sheet should not make a “flopping” sound. Important to note that if a wall is under 12′ or less there should not be a “butt” joint on that wall. all rough edges should be cut out with a utility knife to make the side that is to be taped smooth.
