WARNING
!
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.
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.
TIP: Stainless steel fasteners are
recommended when installing
James Hardie products.

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.
