BLIND NAILING (nailing through top of plank)
Blind nailing is recommended for installing
any type of HardiePlank

lap siding
including ColorPlus

siding. With blind
nailing, each course
covers the fasteners on the course below,
which provides a better
looking installation.
For blind nailing HardiePlank lap siding,
James Hardie recommends driving
Although blind nailing is recommended by James Hardie, face nailing may
be required for certain installations including: installations in high wind areas,
fastening into OSB or equivalent sheathing without penetrating a stud, or
when dictated by specific building codes . Refer to Appendix D for related
code matters.

FACE NAILING (nailing through the overlap at the bottom of the plank)
For walls longer than 12 ft., it is necessary to butt joint additional
lengths of HardiePlank siding. These butt joints should be staggered
to avoid noticeable patterns, which is determined by the placement
of the first course. Butt joints between consecutive courses should
be spaced apart by at least two stud bays for 16-in, o.c. framing or
one bay for 24-in. o.c. framing.
While random placement of the planks is usually the most
aesthetically pleasing, a progressive stagger pattern can make the
job easier and faster without the pattern becoming too noticeable.
With this strategy, the cut off piece for one course becomes the
starter piece for a course above, making efficient use of materials
and ensuring that all butt joints land on studs. The pattern can be
modified for different stud placement.
For walls longer than 12 ft.
land butt joints over studs,
staggering the joints at least
24 in. (for 24-in. o.c. framing)
or 32 in. (two stud bays for
16-in. o.c. framing).

fasteners 1 in. from the top edge of the plank. Additionally fasteners should be placed no closer than
3
/8 in. from the
ends of the plank.
Avoid placing fasteners near the top edge of the plank. This practice, called “high nailing”, may lead to loose planks,
unwanted gaps or rattling. Pinning of butt joints with a finish nail may be done for aesthetic purposes only.
The finish nail should be nailed flush to the surface (not countersunk), must be fully corrosion resistant
(e.g. galvanized or stainless) and does not provide any structural support.
