Before You Begin
Review the general cutting, fastening, and wall preparation instructions in the Cutting,
Fastening, and Wall Preparation sections (page 23-38).
Some important reminders:
Cut Allura Fiber Cement Siding face down with mechanical shears or a circular
saw. Cover the saw table with carpet or another soft material to avoid marring the
surface of the siding.
Prime, paint or caulk all field-cut edges of siding. Do not prime or paint the back of
the siding panel. Refer to instructions on butt joints and trim locations for specific
requirements.
Be sure to install all siding with the proper textured, sealed, or painted surface
facing out.
Do not over drive the fasteners. When a fastener is driven below the surface of the
siding, its holding power is reduced.
Irregularities in framing may be visible in the finished application. To minimize the
effect of uneven walls, shim the wall as necessary.
If you are hand nailing, it may be necessary to predrill the panel to help prevent the
corners from breaking.
Fiber Cement Vertical siding (panels) may be installed only over a flat, vertical
wall surface.
All edges of vertical panels must be backed by framing or solid blocking for
attachment.
Vertical panels can be hung horizontally providing the fastening schedule and
flashing are followed.
NOTE: Do not bridge floors with Allura Vertical panel or trim. A horizontal joint should
always be created between floors.
NOTE: See page 37 for recommended fasteners for Fiber Cement Vertical siding.
Mark a Starting Chalk Line
Establish a straight, level reference line to guide the positioning of the panel.
1. Find the lowest point of the sheathing(s) and make a mark that is 1” above the
lowest corner. Make sure this point is high enough to ensure that the siding is
installed at least 6” above the finished grade or 1” above surfaces where water
may collect.
2. From this mark, snap a level chalk line to the opposite end of the wall.
3. Repeat the procedure around the entire house.
NOTE: Do not install a starter strip.
