with one board on each wall depending
on the desired look.

12 in. apart on adjacent
corner boards.

least 1 in. from
ends and
3

from edges.

Corners made from HardieTrim
®
boards can
be pre-assembled before they’re installed.
Pre-assembled corners look better and
generally make the installation go more
quickly. To join two pieces of HardieTrim
boards for a corner, drive 2-in. 16 ga.
corrosion-resistant finish nails
1
/2 in. from the
edge and spaced 16-in. apart along the edge.
To fasten 4-in. corners to the wall, drive a
pair of finish nails or siding nails, (one nail into
each face of the corner) with the nails spaced
16 in. apart. For 6-in. corners, drive a pair
of finish nails or siding nails into each face
spaced 16 in. apart. Nails should be kept
3
/4
in. from the edges of the board and 1-in. from
the ends.
When walls are more than 10 ft. high, splice
corner boards together using weather cuts
of at least a 22.5° angle. The angle of the
weather cut must slope downward and away
from the building. Then nail both boards to the
building with the same attachment schedule
as for pre-assembled corners, except that
4-in. HardieTrim boards that should get two
nails per side every 16 in. James Hardie
recommends installing trim using
the “Butt-to” method (required for
HZ
™
product zones). “Trim over” is
permitted in HZ10
®
product zones only.
NOTE: All weather cut joints
should be touched up prior to
installation.
