VERTICAL JOINT TREATMENT
Treat vertical joints in HardiePanel
®
vertical siding by using one of the
following four methods:
1) Install the panels in moderate
contact with joint flashing.
2) Leave an appropriate gap
between panels (
1
/8 in. is the
most common), and caulk using
a high-quality paintable caulk,
that meets ASTM C-834 or C-920
requirements. (Not recommended
for ColorPlus)
Panels may be installed first
with caulk applied in the joints after
installation; or as an option, after the
first panel is installed, apply a bead of
caulk along the panel edge. When the
next panel is installed against the first,
the edge embeds in the applied caulk
creating a thorough seal between the
edges of the panels.
3) Vertical joints may be covered with
wood or fiber-cement batten strips.
If James Hardie
®
siding or trim
products are ripped and used as
batten strips, paint or prime the cut
edges. Batten strips should span
the vertical joint by at least
3
/4 in. on
each side.
4 Metal or PVC “H” moldings can
be used to join two sections of
HardiePanel siding.
3 Battened joint
4 H-Channel joint
1 Moderate contact joint
2 Caulked joint
Panels are butted together lightly.
1/8-in. gap left between
panels is lled with caulk.
(not applicable with ColorPlus)
HardieTrim
®
batten board covers
the joint between panels.
Note: The following outlines the recommended applications for ColorPlus and
Primed panels. Not all designs will be suitable for every application:
• Exposed fasteners or battens is the recommended application for ColorPlus products
• Do not use touch-up over fastener heads for smooth ColorPlus products - primed panel
recommended
• For ColorPlus panel applications that require fasteners in the eld, it is acceptable to
use touch-up over fasteners for Cedarmill and Stucco panel only, but correct touch-up
application is important. Some colors may show touch-up when applied over fasteners.
Trim is recommended to cover joints when appropriate.
A manufactured H-channel captures
the vertical edges of the panels.
TIP: Stainless steel fasteners are
recommended when installing
James Hardie products.
