Hold the sheet against the wall while you plumb it. The side with the top shiplap should be along the edge of the wall. Place a 4- foot level along one vertical edge and adjust the sheet until it is plumb. Drive a 1 5/8- inch screw or a 1.
Move to the opposite edge of the sheet, recheck the plumb and make adjustments if necessary, then partially drive a nail or screw into that edge to hold it to the stud. Secure the sheet by driving fasteners along the edge opposite that one, spacing them by 8 inches. Drive fasteners into the studs behind the center of the sheet and along the top and bottom edges, maintaining a spacing of 1. Remove the partially driven fasteners from the edge with the bottom shiplap. Place the next sheet against the first, adjusting it so the tops and bottoms of the two sheets are flush and the top shiplap of that sheet overlaps the bottom shiplap of the one already attached. Since the first sheet is plumb, all subsequent sheets will also be level as long as the joints are properly aligned.
Drive fasteners into the shiplap joint. They should intersect both sheets and sink into the stud behind the joint. Secure the sheet in the same way you secured the first one, leaving the opposite edge unfastened until you fit the next sheet over it.
Measure the last sheet in the row to fit between the second- last sheet and the corner of the wall and cut it with a circular saw. Leave a 1/4- to 1/2- inch gap between the edge of the sheet and the corner to allow for expansion.
The corner trim will cover it. Hang Z- flashing over the top of the row and nail it to the studs before installing another row on top over it. The flashing protects the top edges of the sheets, which are the most vulnerable to water damage. Cut sheets to fit around windows and doors with a circular saw, allowing for a 1/2- inch expansion gap. Trim T1- 1. 1 with 1- by 3- or 4- inch lumber. Nail the trim to the corners of the house and around windows and doors with 8d galvanized finish nails.
It is also common practice to trim the tops to the sheets, where the wall meets the soffit, and the bottoms, where it meets the foundation. Things You Will Need. House wrap or 1. 5 mil tarpaper. Staple gun. Utility knife.
Self- adhering window flashing. Drill. No 2 Phillips bit.
Hammer. 4- foot level. Circular saw. Z- flashing. Tips. Paint or stain T1- 1. If you paint it, giving it a coat of exterior primer adds protection and increases paint adhesion and coverage. Prime all four edges of each sheet before you hang it as a safeguard against moisture damage.
Warning. T1- 1. 1 should never be installed in contact with the ground. Ground contact introduces moisture that causes the plywood to separate and promotes mold. About the Author.
