TIP: When
installing HardiePlank
lap siding with ColorPlus
Technology, position the plank
in the immediate area where
the plank is to be fastened.
Do not place the plank on the
course below and slide into
position. Doing so may scuff or
scratch the ColorPlus finish on
the installed piece.
Caulking at HardiePlank lap siding butt
joints is not recommended for ColorPlus
for aesthetic reasons as the caulking and
ColorPlus will weather differently. For the
same reason, do not caulk exposed nail
heads. Refer to the ColorPlus touch-up
section for details
Do not use caulk on HardiePlank

JOINT FLASHING
One or more of the following joint treatment options are required by code (as
referenced 2009 IRC R703.10.2)
A. Joint Flashing (James Hardie recommended)
B. Caulking* (Caulking is not recommended for ColorPlus for aesthetic reasons
as the Caulking and ColorPlus will weather differently. For the same reason, do
not caulk nail heads on ColorPlus products.}
C. “H” jointer cover
Flashing behind butt joints provides an extra level of protection against the
entry of water at the joint. James Hardie recommends 6 in. wide flashing that
overlaps the course below by 1 in. Some local building codes may require
different size flashing.
Joint-flashing material must be durable, waterproof materials that do not react
with cement products. Examples of suitable material include finished coil stock
and code compliant water-resistive barriers. Other products may also be suitable.
Butt joints in HardiePlank lap siding should always land on
a stud. Butt joints between studs are not recommended
and should be avoided. Whenever possible, factory-
finished ends should be used at butt joints.
Place cut ends where the siding meets a corner, door,
window trim, or other break in the wall where the joint is
to be caulked. If cut ends are used in a butt joint between
planks, James Hardie requires sealing cut ends for all
products. For ColorPlus products, use the color-matched
edge coater to seal the cut end.
TIP: Joint flashing can be quickly and easily made by cutting a 6 in. wide section
off a roll of housewrap. Tape the roll tightly at the cut mark and cut the section off
using a miter saw with a carbide blade. Individual sheets then can be cut to length
with a utility knife.
TIP: Use light-colored joint flashing when using light-colored ColorPlus lap siding
or other siding with a light-colored finish. Dark-color joint flashings should be
used on siding with dark finishes.
