Justin: Hanging drywall on an exterior wall uses the same fundamentals as hanging the ceiling, but there are more holes: electrical outlets, windows, doors, and service chases. Before hanging the walls, cut back all of the canned foam applied to the ceiling perimeter, any obstructions around windows, and if not done on the pre-construction walk-through, seal all of the gaps between framing members.
Myron: Remember, you want to keep things clean, because wherever the adhesive is going to be used, it won’t stick as well if it is dusty and dirty. We’re going to have a seam up here, and then another seam right down here. That way, our butted seams are falling in the window frame area.
Justin: Again, the face of the studs gets a thick bead of adhesive. Windows get the royal treatment. Use both latex caulk and polyurethane construction adhesive.
Myron: I’m going to be careful that when I apply the adhesive, I want it to actually intersect with the caulking that we have on here so that we get a continuous seal. You’ve probably noticed that I am really piling on the adhesive and the caulking. The tip here is: this is not the place to skimp on materials. Use plenty of it, because we really want to make a good seal.
Justin: Place the left edge of the sheet into the corner and then lay the rest of it flat against the framing, caulk, and adhesive.
Myron: Looks good. It’s important that when you fasten the drywall, you put it right into place without moving it around and smearing the adhesive.
Let’s be careful not to smear it. I want to go right where I want to put the top edge in first. I’m good here.
