How to Install Wall Sheathing
A quick look at the right way to skin a stud wall.
From the underlying framing to the water barrier, this video lets you tackle wall sheathing in a minute.
Wall sheathing starts with making sure the underlying wall framing is square.
The first sheet should hang below the bottom wall plate to tie into the framing below. A line snapped across the studs orients the top of this sheet.
The second row of sheathing should be offset at least three stud bays from the first.
Mark the location of window and door openings with tick marks.
Use the right nails – At least 2 in. long ring-shanked nails are required, and they should be spaced no further apart than 12 in. in the center of the sheet and 6 in. along supported edges.
The nails should be about 3/8 in. in from the edges. Angling the nailer helps to ensure the nails hit the studs along the ends of the sheets.
Ideally, the nails should be driven just flush with the face of the sheathing.
Using the tick marks made earlier as starting points, snap lines at the edges of the openings and cut them out with a circular saw.
For standard OSB or plywood sheathing, install housewrap using cap fasteners.
When using sheathing with an integrated water-resistant barrier, remove any dust or debris from the surface and tape all seams flashing-style using a j-roller to embed the tape.
