PRIOR TO INSTALLATION
• Inspect product for any issues before
installing. (breakage, surface defects,
foreign objects, color inconsistency or
color correctness)
• Do not install questionable product.
• Report any problems you may have to
your dealer BEFORE installing.
STORAGE
It is important to properly store all Diamond
Kote
®
products for protection.
• Store siding at on a dry, clean and well
supported surface. Protect material from
direct exposure to weather.
• Do not store directly on the ground.
• Diamond Kote
®
4-Packs and 2-Packs
are not waterproof. All products must be
kept dry and covered at all times.
• Product may come in long, heavy
sections, which requires proper handling.
• Carry shrinkwrapped bundles to
desired location before opening to
avoid damaging the painted surface.
• Don't carry in a at position.
• Pick up product from the center to avoid
marring the surface of items below.
• Only carry multiple pieces of siding:
face-to-face or back-to-back.
• Do not slide pre-nished siding material
across each other.
• Support the product when you cut large
pieces.
• Sealed product could become saturated
if not protected during storage.
• If the product becomes saturated, do not
install until it dries out completely.
GENERAL GUIDELINES
**Note: DO NOT USE STAPLES.
Minimum 6" clearance must be maintained
between siding and nish grade.
• Siding applied adjacent to porches,
patios, walks, roof lines, etc. must have a
1" clearance above any surface.
• 3/8" clearance should be left between
siding and horizontal ashings.
• All exposed wood substrate must be
primed and painted to prevent moisture
intrusion and water buildup.
• Best practice for blind or exposed nailing
is to use only 316 stainless steel nails
within 15 miles of the seacoast. Beyond
15 miles, either 304 stainless steel or
hot-dipped galvanized is acceptable.
• See Alternate Fastening Options for
fastening lap siding to SIP, ICF and Steel
Frame assemblies.
(PG 10)
• Adequate drying time must be allowed
prior to enclosing the wall cavity when
using wet blown cellulose insulation.
• With wet blown cellulose insulation, the
insulation must not be in direct contact
with the siding and it will need time to
dry, a minimum of 24 hours or longer if
specied by the insulation manufacturer.
• Diamond Kote
®
Building Products should
be cut in a manner to avoid marring the
nished face.
• It is recommended to face the board up
when using a combination blade power
miter saw.
• Do NOT force or spring siding into place.
Where siding butts window trim, door
casing, masonry, etc., leave a 3/16" gap
and caulk. DO NOT caulk butt joints.
• Seal all gaps with a paintable sealant
that meets ASTM-C92
0 Specication,
it is recommended to use DAP SpecLine
92
0.
• Use drip-cap ashing above all
horizontal trim to ensure a weather-
tight installation. 1" drip cap is available
in all Diamond Kote colors.

INSULATED SHEATHINGS
Diamond Kote
®
Building Products may be
installed over low-compression rigid foam
or exterior gypsum sheathings.
The following precautions must be followed:
• Nailable structural sheathing must be
behind the insulated sheathing.
• Make sure to brace the wall accordingly
to the required international and other
building codes.
• For rigid foam sheathing up to 1" thick,
siding may be nailed directly to the foam
sheathing unless a drainage plane is
required by the local building code. Nail
length must be increased to ensure a
minimum 1-1/2" fastener penetration
into the structural framing.
Note: Diamond Kote
®
Building Products
may also be installed in compliance with
category 8140-Exterior wall siding and
sheathing for Wildland Urban Interface
applications atop LP
®
FlameBlock
®
sheathing. Refer to FlameBlock
®
installation
instructions and product data sheets.
All Diamond Kote
®
Building Products may
be installed as exterior siding in Wildland
Urban Interface applications. It can be
installed over one layer 5/8" Type X gypsum
sheathing applied behind the exterior
covering or cladding on the exterior side of
the framing. They may also be installed over
the exterior portion of a 1-hour re-resistive
exterior wall that has been assembly
designed for exterior re exposure which
also includes assemblies using the gypsum
panel and sheathing products listed in the
Gypsum Association Fire Resistance Design
Manual.
• For rigid foam sheathing that is greater
than 1", a minimum 1-1/2" thick by
3-1/2" wide vertical strapping or furring
strip must be installed over the sheathing
to provide a solid, level nailing base
for the siding. The strapping must be
securely fastened to structural framing
spaced no greater than 16" o.c. with a
minimum fastener penetration of 1-1/2".
• Diamond Kote
®
Building Products will not
assume any responsibility for conditions
arising from the use of foam sheathing or
damage.
MOISTURE
• Moisture and vapor control are critical
elements of proper housing design.
• Check local building codes for application
procedures for handling moisture and
moisture vapor in your area.
• Do not apply engineered wood siding to
a structure having excessive moisture
conditions such as drying concrete or
plaster or wet blown cellulose insulation.
• If conditions exist, the building should be
well ventilated to ensure the substrate is
completely dry prior to siding.
• Siding must not be applied to any green
or crooked structural framing members.
• Do not apply siding over rain-soaked or
buckled sheathing materials.
• We recommend protection for your
home from rainfall with gutters and
downspouts. Always be sure that your
drainage system is free of debris and
working properly.
WEATHER-RESISTANT BARRIER
• It is required to have a water-resistant,
properly breathable barrier behind the
siding.
• When integrating ashing with a water-
resistive barrier (WRB), be sure to follow
the WRB installation instructions.
• Diamond Kote
®
Building Products will
not assume responsibility for water
penetration.
• Consult local building codes for more
details.
TRIM & FASCIA 190, 440, 540 & 2000 SERIES
INSTALLATION
• Trim ends may lightly touch adjacent trim edges around windows and doors only. Re-prime and paint all cut ends.
• When installing trim around windows and over window anges, be sure to follow the window manufacturer’s installation
instructions.
• All openings must be properly sealed and ashed in a manner that prevents moisture intrusion or buildup. Flashing may be
sealed to the water-resistive barrier by using adhesive ashing or housewrap tape. (See ALL diagrams)
• When trim is installed adjoining vinyl siding, install Z-ashing with a 4 inch upper leg between horizontal trim and J-channel.
(See diagram 8a)
• Horizontal trim or bands shall be ashed with a sloped metal Z-ashing to redirect water away from the wall assembly.

spaced no greater than 16" on center.
• When installing over masonry walls,
the wall must be furred out with wood
framing spaced 16" on center and with
a adequate thickness to accept the full
length of the recommended nail.
GAPS AND SEALANTS
Note: DO NOT apply sealant to butt joints.
• Seal all gaps with a paintable sealant
that meets ASTM C92
0 Specication.
• We recommend the DAP
®

TOUCH-UP PAINT GUIDELINES
Before starting, read all label instructions
and warnings. Diamond Kote
®
touch-up
paint is intended for use on Diamond Kote
®
pre-nished products only. We cannot
guarantee the performance of Diamond
Kote
®
touch-up paint on products not
originally pre-nished with Diamond Kote
®
.
Only apply paint to bare area. DO NOT
APPLY PAINT OVER PAINT. *Do not allow
touch-up paint to freeze. Keep container
from freezing.*
For Touch- Up Paint, please do the following:
• Paint all exposed cut edges of siding
surfaces including drip edges.
• Apply a small amount of touch-up paint
using the provided foam brush to seal all
cut edges.
• Avoid getting touch-up paint on the face
of the boards and try not to apply more
paint than what is needed.
• Thoroughly paint all the bottom edges of
siding especially the cut ends next to the
roof line. Touch-up paint all exposed face
nails.
• Cotton swabs are recommended for
touch-up painting on the nished face of
products.
• Follow the Diamond Kote
®
application/
maintenance instructions and/or watch
the Diamond Kote Touch-Up Paint Best
Practices Video.
PAINT CARE
• Stir touch-up paint for ten minutes
before use. Heavier pigments in the paint
settle to the bottom requiring the paint
to be thoroughly mixed before use and
cleaned up with water after.
SURFACE PREP
• Surface must be clean and dry. Test the
color on a sample piece or hidden area of
the siding/trim before applying. Do NOT
fan out or try to blend the paint.
• Allow 24 hours dry time. Touch up nail
heads or small imperfections by using a
cotton swab to dot the desired area.
TRIM
• Trim should be thick enough so the
siding does not extend beyond the face
of the trim.
• Trim and fascia are not designed for
siding/structural applications. It should
not be used as a structural member in
construction (trellis, railing, fencing,
decking, decking trim or sills.)
• Trim must be applied so it will not allow
moisture intrusion or water buildup.
• LP
®
Lap and Panel siding is not designed
and/or manufactured to be used as trim
or fascia. LP
®
SmartSide
®
trim and fascia
are available in a variety of dimensions.

TRIM | FASTENER INFORMATION
• Fastener length: Long enough to fully
penetrate structural framing or wood
structural panels and structural framing
a minimum of 1".
• Fastener placement: 3/8" from ends and
edges, when framing support allows.
• Fastener spacing: Must be fastened with
two nails at both ends, with additional
fasteners spaced a maximum of 24
inches o.c. along the length of the board,
or with additional fasteners spaced a
max. of 12 inches o.c. along alternating
edges the length of the board.
• Fastener quantity: For trim under 7
inches wide use a minimum of 2 nails per
width. For trim 7 to 12 inches wide use
a minimum of 3 nails per width. For trim
over 12 inches wide use a minimum of 4
nails per width.
• Where edges of trim meet siding material,
windows, etc., leave a min. 3/16 inch
space to allow for proper sealing.
Provide increased spacing along the
trim if specied by the siding application
instructions.
CUTTING
• A ne-tooth carbide tipped blade is
recommended for the cleanest cut.
• Trim and fascia are manufactured with
a special edge coating which reduces
moisture-related issues.
• Don't rip and/or route the trim and fascia,
as it will leave the edges unprotected.
• If the trim/fascia materials are ripped
you must take special care to prime,
paint and seal all exposed wood ber as
described in the nishing section.
• Do not miter trim ends or edges. 45
degree diagonal cuts of trim ends around
door and window opening is acceptable,
as well as joining.
(See below)
BUTT JOINTS FOR TRIM
• Ends and butt joints require a 3/16 inch
space and seal with a high quality non-
hardening paintable long-life sealant.
Joints may lightly touch around windows
and doors only.
• Butt joints require 4 nails with 2 nails on
either side of the joint at each edge.
TRIM ADJOINING WITH OTHER MATERIALS
• Trim with Stucco, Brick or Cultured Stone:
it is important to use a capillary break so
moisture absorbed into the stucco, brick
/cultured stone can not transfer into the
trim. Avoid direct contact between the
trim and stucco, brick or cultured stone.
• Separate with a min. 3/8-inch space
and a high-quality sealant
(backer rod may
be required as per the sealant manufacturers
instructions). Additional space may be
required by the manufacturer of the
stucco, brick or cultured stone cladding.
• Other types of material like aluminum
ashing can be used to separate the
trim from the stucco, brick or cultured
stone but dissimilar materials should be
properly spaced to allow for dierent
rates of thermal or moisture movement.
• Apply sloped Z-ashing over horizontal
trim so water can be redirected to the
outer surface of the wall.

• For rigid foam sheathing up to 1 inch (25.4 mm) thick, trim may be nailed directly to the foam sheathing unless a drainage
plane is required by the local building code. Nail length must be increased to ensure a minimum 1-1/2 inches (38.1 mm)
fastener penetration into the structural framing.
• For rigid foam sheathing greater than 1 inch (25.4 mm) thick, a minimum 1-1/2 inches (38.1 mm) thick by 3-1/2 inches
(88.9 mm) wide vertical strapping or furring strip must be installed over the sheathing to provide a solid, level nailing base
for the trim. The strapping must be securely fastened to structural framing spaced no greater than 16 inches o.c. (406 mm)
with a minimum nail penetration of 1-1/2 inches (38.1 mm) and a maximum nail spacing no greater than the width of the
siding.
Louisiana-Pacic assumes no responsibility for any damage or condition arising from the use of rigid foam or exterior
gypsum.

PREPARATION
• Moisture control and moisture vapor control are critical elements of proper housing design and construction. Check your
local building codes for application procedures for handling moisture and water vapor in your area.
• Follow all applicable building code specications relating to prevention of moisture intrusion into the wall assembly. LP
SmartSide trim and fascia is a wood product, and, as with all wood products, must be kept free from excessive moisture.
Lack of proper ventilation; exposure to constant or repetitive sources of water such as sprinklers, condensation, inadequate
ashing; improper sealing; or failure to follow common building practices that prevent moisture intrusion into the wall
system may cause damage, and products subject to such treatment will be excluded from warranty coverage.
• As with all wood products, do not apply engineered wood trim and fascia to a structure having excessive moisture
conditions such as drying concrete, plaster, or wet blown cellulose insulation. If such conditions exist, the building should be
well ventilated to allow it to dry prior to the application of the trim and fascia.
• Gutters with kick-out ashing and eave drip edge are recommended for control of roof water run o.
GENERAL REQUIREMENTS (CONTINUED)
• Apply nails to meet the specications in the General Application
Equipment section in this document. (See diagram 3c)
• For edge-nailing, all nail holes must be pre-drilled. Do not
attempt to edge nail without pre-drilling.
(See diagrams 6e and 6f)
• Fastener length: Long enough to fully penetrate structural
framing or wood structural panels and structural framing a
minimum of 1 inch.
(See diagram 4a)
• Fastener placement: 3/8 inch from ends and edges, when
framing support allows.
• Fastener spacing: Trim must be fastened with two nails at both
ends, with additional fasteners spaced a maximum of 24 inches
o.c. along the length of the board, or with two nails at both ends,
with additional fasteners spaced a maximum of 12 inches o.c.
along alternating edges the length of the board.
(See diagram 4b)
• Fastener quantity: For trim under 7 inches wide use a minimum
of 2 nails per width. For trim 7 to 12 inches wide use a minimum
of 3 nails per width. For trim over 12 inches wide use a minimum
of 4 nails per width.
• Where edges of trim meet siding material, windows, doors or
other nished openings, leave a minimum 3/16 inch space to
allow for proper sealing. Provide increased spacing along the
trim if specied by the siding application instructions.
• Do not miter corner joints of band boards, fascia, corner trim,
etc. (See diagram 2e)

WHERE TO FASTEN - SIDING
• Fasteners will be exposed on the siding
located immediately below window sills,
fascia boards, and horizontal trim.
• Fasteners below window sill shall be
spaced a maximum of 8" on center.
• Face nailing may be required as
necessary in order to obtain satisfactory
installations. Blind fasten 3/4" down
from the TOP edge.
• For installation with or without wood
structural panels, joints must occur over
stud locations.
• Best practice for blind or exposed nailing
is to use only 316 stainless steel nails
within 15 miles of the seacoast. Beyond
15 miles, either 304 stainless steel or
hot dipped galvanized is acceptable.
• Nail at all special framing members
around openings.
Note: Nails MUST penetrate framing
members when available at least 1-1/2".
Nail from the center of the siding toward
the ends, or from one end to the other end.
NEVER nail from the ends of the siding
toward the middle.
• Shim siding at studs as needed, to avoid
drawing siding against uneven walls.
• When installing siding over up to 1" rigid
foam sheathing be careful not to drive
fasteners so hard as to compress the
foam and distort surface of the siding.
Note: DO NOT OVERDRIVE FASTENERS.
Head should seat rmly to face of siding,
but not be overdriven to distort the siding
surface.
For info on fastening any of the decorative
shape products in high wind speed areas,
please refer to ICC-ES Report ESR-1301.

trim
should extend beyond the face of the siding.
Watch our RigidMount
™
Installation Video.
APPLICATION
• Start by preparing for the application
needed. Some cutting maybe necessary
for tment of your specic situation.
• Cuts should always be re-sealed with
touch up paint.
• A jigsaw works best for cutting, be sure
to cut from the back to keep the nished
surface intact.
• Set the mount into position and mark the
weather resistive barrier by using the
nail holes (about 1/2" above the built in
ashing) and the outside edges of the
ange.
• Remove the mount and slit the weather
resistive barrier horizontally (slightly
wider than the top ange across those
marks) creating a ap in the weather
resistive barrier.
• Next install the RigidMount
™
by slipping
the top of the nailing ange under the
weather resistive barrier ap.
• Set the mount at the correct elevation,
level and then fasten the RigidMount
™
to
the wall lling every hole in nail ange.
• Hand driven galvanized roong nails are
recommended for fastening, such as
1-3/4" Maze STORMGUARD
®
.
• Place the adhesive ashing tape over the
top of the RigidMount
™
ange making
sure to cover nailing holes.
• Fold the ap down and seal the slit in the
weather resistive barrier with compatible
building tape.
• This single fashion installation helps
shed bulk water out and away from the
structure.
• Install siding around the mount and
leave the proper spacing between the
RigidMount placement ange and the
siding.
(Min. 3/16")
• Note that the top course of siding should
be cut 3/8" above the built in ashing as
measured from the face of the siding.
• Make sure to seal cut edges of siding
with provided touch-up paint. This area
should be left uncaulked.
• Finish by applying sealant, starting
approximately 3/4" in from the top
corner and then working your way out,
down the side, and across the bottom.
• Also seal the space between the wall
penetrating material and the RigidMount
™
cut out.
• DAP

• Please note details on proper gluing.
• Measure each post locations separately
as there may be variance from post to
post.
INSTALLATION
• Begin by cutting all four sides to the
desired length.
• Be sure to repaint all cut ends of the Pro-
Post Wrap™ with Diamond Kote
®
touch-
up paint before assembly.
• Start with two boards and begin
assembling by applying an even bead of
the supplied glue, about 1/8", to Groove
A on one board and then Groove B on
the other board this will create an "L"
shaped piece.
• When assembling the 4x6 post be sure
to glue Groove B on the 4" board and
Groove A on the 6" board. Assemble so
the 4" board is the top of the "L" and the
6" board is the bottom of the "L".
• Working quickly, assemble the pieces
and clamp as necessary using bar clamps
to bring the joints together tightly. Apply
enough pressure to secure tment being
careful not to break edges of trim.
• Repeat this step in order to create a
second "L".
• Next, glue Groove A and Groove B on
one of the "L" shaped pieces.
• Join the two "L" shaped pieces around
the post to be wrapped creating a 4-
sided post wrap. Clamp as necessary
using bar clamps to bring the joints
tightly together. Leave the clamps
installed until the glue sets (approx.
5-10 min.)
• Installations in cold temperatures or dry
climates may require longer clamping
times. Position the wrap on the post for
best appearance and plumb as needed.
• Begin fastening on the side that is in
the most direct contact with the post.
Be careful to keep the nails away from
the structural post mounting hardware.
Fasten around the post, with one nail
minimum, at the top and bottom on all 4
sides. Touch up paint all the nail heads.
• You can complete the installation with a
site built trim ring. The best practice is to
keep LP
®
SmartSide
®
trims 3/8" above
ashings and/or 1" above concrete
or decks. Trim rings constructed of
PVC trim are recommended for areas
close to grade. Items installed without
the proper clearances to grade may
not be covered under manufacturers
warranties.

SPACER FLASHING INSTALLATION
GENERAL
• Spacer Flashing is designed to allow for
the minimum clearance requirements
for proper spacing between siding
materials and roong, decks, driveways,
or sidewalks.
SPACER INSTALL:
• Spacer Flashing can be installed with
side "D" in moderate contact, or slightly
gapped from the roong, deck, driveway,
or sidewalk.
• It is recommended to close the open
end of the Spacer Flashing by making
approximately 1" deep cuts on the
bends (circled in Spacer Diagram) in
from the end of the piece. Then bend the
tabs created from those cuts inward in
this order: B, D, then C.
• Fasten through side "A" to the wall every
12-16" on center. Place fastener ¾"
down from the top of side "A".
• Properly integrate ashing with the
secondary water-resistive barrier.
• Use house wrap, ashing tape, or other
items as needed to maintain the counter
ashing principle.
• When installing siding, it's important
to retain 3/8" minimum clearance
between the siding panels and side
"B" of the Spacer Flashing and DO
NOT caulk.

SPACER CLIPS
• Hook clip to top of the rst row of siding.
• Slide siding down into clip shelf.
• Follow the manufacturer’s directions
for nailing and then strike the clip with
hammer to knock it o.
Note: Spacer clip is intended for alignment
and spacing only. It's not intended to
support the weight of the siding. Break
o clips before siding is completely nailed
tight.
JOINT PREPARATIONS H-MOLDING
Note: H-Moldings DO NOT space the board
for expansion. H-Moldings are designed to
cover the expansion gap.
• Leave a 1/4" gap between the siding
pieces. 3/16" gap plus the thickness of
H-Molding web equals 1/4".
• Apply both adjoining pieces of the
siding, fasten along the entire length
(except for the ends) with the required
gap. Be sure to butt the factory painted
ends of the board over the stud.
• Then, slide the H-Molding in place, from
the bottom of the siding up, with the
notched end of the molding down.
Slightly bend outward on the anges to
help the H-Molding slide into place. (See
Figure 2a)
• Finish fastening by nailing both pieces of
siding at the end of the siding. Angle the
nails slightly to hit the stud.
• At butt joints, fasteners should be driven
3/4" down from the top and 3/8" in from
the ends.
• Fasteners below a window sill need to be
spaced a maximum of 8" o.c. Fasteners
will be exposed on the siding located
immediately below window sills, fascia
boards, and horizontal trim.
• When attaching siding, avoid nailing
closer than 1-1/2" from the end of

properly hold the bottom of RigidStack in place.
Placement may vary as required by course lay-
out. (see figure 11B)
Snap a level chalk line 3-3/8” above the bottom of
where the first course of siding will start. Align the
TOP of the metal starter strip on the chalk line.
RigidStack metal starter strip will set the exact
placement for the 1st course of RigidStack.
Fasten the RigidStack metal starter strip every 12-
16” o.c.
For metal starter strip install begin here:
Figure 11B
Install StarterBoard using the recommended Cortex
Concealed Fastening System in the following manner:
Using the Cortex setting tool, set the Cortex fasten-
ers perpendicular to the trim board, spaced a maxi-
mum of 16" o.c. Using a standard 18V cordless im-
pact drill, drive the fastener to the pre-set level be-
low the trim surface. Place the PVC trim plug into the
hole with the trim-surface-side up, and gently tap
until it is flush with the trim board. Finish by painting
the plugs with Diamond Kote touch up paint and a
cotton swab.
5. Fasten the siding by nailing through the nailing
line (about 3/4” from top edge of siding) at
EACH STUD LEAVING NO MORE THAN 16 in. BE-
TWEEN NAILS. Begin nailing at one end of the
siding and work toward the other end to prevent
rippling of the siding. Do not countersink nail
heads.
6. Then install subsequent courses of siding so that
the plastic spline fits over the top edge of the
previously installed piece of siding.
7. The butt joints between adjacent siding pieces
must be located over the middle of a stud.
Make sure that the spline is firmly seated to the
top of the previous course BEFORE and DURING
nailing to ensure the material lines up at the butt
joints and at course lines at the corners.
3. Now install the first course of siding so that the
plastic spline fastened into the back of the sid-
ing fits over the beveled edge of the starter
board (Figure 11A) or into the metal starter strip
as shown in (Figure 11B).
4. LEAVE A 3/16” GAP WHERE SIDING BUTTS
AGAINST TRIM TO ALLOW FOR EXPANSION. See
Figure 11C.

RIGIDSTACK™ INSTALLATION
• Now install the rst course of siding so
that the plastic spline fastened into the
back of the siding ts over the beveled
edge of the starter board
(Figure 2b) or
into the Metal Starter Strip, as shown in.
(Figure 2c; both on pg 12)
Note: Leave a 3/16" gap where siding
butts against trim to allow for expansion.
• When attaching siding, avoid nailing
closer than 1-1/2" from the end of the
board to avoid penetration of the power
nails into the nail n.
• Fasten the siding by nailing through the
nail line
(about 3/4"
from top edge of siding)
at each stud, leaving
no more than 16"
between nails.
• Begin nailing at one
end of the siding and
work toward the other end to prevent
rippling of the siding. Do not countersink
nail heads.
• Then, install subsequent courses of
siding so that the plastic spline ts over
the top edge of the previously installed
piece of siding.
• Make sure that the spline is rmly seated
to the top of the previous course by
pushing in and slightly down on the face,
BEFORE and DURING nailing, to ensure
the material lines up at the butt joints
and at course lines at the corners.
• At some point during the installation it
may be necessary to remove the spline
from the back of RigidStack™ in order to
make the courses line up at corners or to
adjust for an out of level wall. Removal
of the spline is not uncommon and
does not void the substrate or nish
warranty. To remove the spline grasp
it using a pliers at rst, then with your
hand. Wiggle it back and forth while
pulling upwards, continue until the entire
spline is removed.
RIGIDSTACK JOINT PREPARATIONS
USING H-MOLDINGS
• When using RigidStack™ siding the butt
joints are REQUIRED to be covered with
an H-Molding.
(Figure 2f)
H-Moldings DO NOT automatically space
the board for expansion. They're designed
to cover the expansion gap.
• Leave a 1/4" gap between siding pieces.
3/16" gap plus thickness of H-Molding
web equals 1/4".
• The butt joints between adjacent siding
pieces must be located over the middle
of a stud.
• Best method is to apply both adjoining
pieces of RigidStack™ fastening along
the entire length except for the butt joint
ends.
• Slide the H-Molding in place from
the bottom of the siding, with the
notched end of the molding down.
Bending slightly outward on the anges
rst will help the H-Molding slide into
place more easily.
(Figure 2f)
• Finish fastening by nailing, both pieces
of siding at the end of the siding and
angle the nails slightly to hit the stud.
• At butt joints, fasteners should be driven
3/4" down from the top and 3/8" in from
the ends.
• Fasteners below window sill need to be
spaced a maximum of 8" o.c. Fasteners
will be exposed on the siding located
immediately below window sills, fascia
boards, and horizontal trim.

• Do NOT place fasteners into bottoms of
grooves or shiplaps.
• Fasten the siding by nailing through
the nailing line 3/4" down from the
top of panel, into the sheathing and/or
framing with one of the below options.
• For screws, fasten 12" o.c. use a
minimum #8 corrosion resistant tapered
head wood screw.
(see Figure 3c)
• For nails, fasten 8" o.c. use a minimum
6d (0.09" shank diameter) corrosion
resistant ring shank nail.

• Continue row, working left to right.
Overlap shiplap butt ends without any
gap.
(see Figure 3e)
• Start subsequent courses in same
manner, but trim each course to create
the eect of staggered joints.
• Best appearance is obtained by trimming
the second course starter piece 16"
shorter than the rst course, and
trimming the third course starter piece
32" shorter than the rst.
• Repeat this same sequence every 3
courses.
• Shim siding at studs, as needed, to avoid
drawing siding against uneven walls.

• Fasten 3/4" down from the top of the
panel, into sheathing and/or framing
with one of the below options.
• For screws, fasten 12" on center using a
minimum #8 corrosion resistant tapered
head wood screw.
(see Figure 4c)
• For nails, fasten 8" on center using a
minimum of 6d
(0.09" shank diameter)
corrosion resistant ring shank nail.
(see
Figure 4d)
• Continue row, working left to right.
Overlap shiplap butt ends without any
gap.
(see Figure 4e)
• Start subsequent courses in same
manner but trim each course to create
the eect of staggered joints.
• Best appearance is obtained by trimming
second course starter piece 16" shorter
than the rst course and trimming the
third course starter piece 32" shorter
than the rst. Repeat this same sequence
every three courses.
(see Figure 4)
• Shim siding at studs, as needed, to avoid
drawing siding against uneven walls.
• Then install subsequent courses of
siding so that the plastic spline ts over
the top edge of the previously installed
piece of siding.

OCTAGONS + SCALLOPS APPLICATION
Prior to installation: Find the center of the
gable or wall so that shapes will be visually
centered. For best nished appearance,
gable installations should end with a single
Scallop or Octagon at the peak.
STRAIGHT WALL APPLICATION
• Begin by measuring the length of the
wall between the corner trims.
• Next, divide length of wall by two to nd
the center of the wall.
• Mark the center of the wall.
• The easiest layout for the Octagons or
Scallops to be visually centered on the
wall, is to start so that a keyway lands
over the center of wall mark.
• Calculate the layout of full panels from
the center mark and make a mark on the
wall (full panels measure 48").
• Measure from the trim to the mark so
that siding section ts against corner
board, with a 3/16" gap.
• Trim left side of a panel to t and begin
installation.
GABLE APPLICATION
• Start by dropping a plumb line to nd
the center of the gable. Mark this line.
• Next measure the height of the gable
(in inches) on this line. For Octagons
divide by 9-5/8". For Scallops divide by
7-3/4".
• The purpose of this simple equation is
to nd out the number of courses or
rows.
• Then, divide the height of the gable by
the size of the exposure of the prole
that will be installed.
• Example: 64" gable height with scallops.
(64"÷ 7.75" = 8.25 - Eight is an even number, do
not worry about the decimal, center on a keyway
to start.)
• If the answer is an even number, center
the rst course of Scallop or Octagons
on a keyway.
• If the answer is an odd number, center
the rst course on a Scallop or Octagon.
• Begin by locating the rst piece relative
to the centerline of the gable. The panel
may be positioned anywhere along its
length, as long as the keyway or shingle
face is centered.

OUTSIDE + INSIDE CORNER
WITH NAIL FIN APPLICATION
It is recommended to install corners
with nailing n over nailable structural
sheathing. Some face nailing may be
required if nailable sheathing is not
present.
• Apply corners over properly prepared
walls.
(see general guidelines pg 2)
• Diamond Kote
®
Outside and Inside
Corners with Nail Fin are designed to
be installed blind nailed through the
attached nail ns to help complete a
hidden fastener install.
• Install corners and trims rst before
beginning ins tallation of the siding
products. Start by carefully removing
the corners from protective shipping
packaging. Do not cut packaging on
face of material.
• Avoid drawing corners against uneven or
out of square walls. Before installation
make sure that the foundation or
foundation coverings do not project
beyond the plane of the wall.
• Shim as necessary to avoid potential to
split corners lengthwise.
FINGER JOINTS
• 10' Corners are manufactured with a
random nger jointed trim board. For
aesthetic purposes it is recommended
to attempt to turn, ip, and/or cut o
corners in order to reduce the visibility
of the nger joints around high trac
areas of the building. 16' corners DO
NOT contain nger joints.
CUTTING
• Measure and mark corners for length
typically 1/2" - 3/4" lower than the
bottom course of siding.
• Cut outside corners carefully to avoid
marring the nished surface, 4" corners
can be cut utilizing power compound
miter saws. 6" corners typically require
cutting by hand or by circular saw.
• It is recommended to cover the bed of
circular saws with tape or protective
coverings to avoid marring the nished
surfaces.
SEALING
• Cotton swabs are recommended for
touch-up painting on the nished face
of products. Paint and/or seal ALL cut
ends and edges of corners.
(see Figure 7a)
NOT RECOMMENDED to use pneumatic
roong, or siding nail guns to install
trim with nailing n.
• When attaching siding, avoid nailing
closer than 1-1/2" from the end of
the board so the power nail does not
penetrate the nail n of Diamond Kote
®
Trims.
• Use hand driven galvanized roong nails
for installation on Corner.
• 1-3/4" StormGuard Ring shank nails
from Maze Nails are recommended.
• When installing inside and outside
corners over
(up to) 1" rigid foam
sheathing, be careful not to drive nails
so hard as to compress the foam and
distort the n. Nail length must be
increased to ensure penetration of the
wood substrate.
Figure 7a

23 | Diamond Kote Building Products Application Guide 6.18
OUTSIDE + INSIDE CORNER
WITH NAIL FIN APPLICATION
INSTALLATION
• Hold outside and inside corners with
nailing n up to the wall, level, plumb
and set it to the correct height before
nailing.
• Alternate nailing through the n in the
provided holes on both sides of the
corner.
• Fasten EVERY 3RD HOLE. (Figure 7b)
• DO NOT OVERDRIVE NAILS.
• Nail heads should be set rmly to the
face of n, but should not be overdriven
to distort or damage the n surface.
STACKING:
• FOR 2 CORNERS, ONE JOINT: Lightly
butt painted cut ends together and leave
a 3/16" gap where the top corner meets
the sot.
• FOR 3 OR MORE CORNERS 2+ JOINTS:

TRIM WITH NAIL FIN APPLICATION
• Apply trim over properly prepared walls.
(general guidelines page 2)
• It's recommended to install Diamond
Kote
®
Trim with Nail Fin over nailable
structural sheathing.
• If nailable sheathing is not present, some
face nailing may be required.
GENERAL
• Trim with nail n is designed to be blind
nailed through the attached nailing n
and with clip to help complete a hidden
fastener installation.
• Install the outside corners and trim rst
before installation of siding products.
• Start by carefully removing trim from
protective shipping packaging.
• Do not cut packaging on face of material.
Avoid drawing trim against uneven or
out of plane surfaces. Shim as necessary
to ensure acceptable trim joints.
CUTTING
• It is recommended to cut the trim with
nail n face up and to utilizing power
compound miter saws.
• Align edge of trim without attached n
against fence.
• When cutting by circular saw, it is
recommended to cut face down.
• Be careful to avoid marring the nished
surfaces.
SEALING
• Paint and/or seal ALL cut ends and edges
of trim. (Figure 7a pg. 17) Cotton swabs are
recommended for touch-up painting on
the nished face.
TRIM NAILING REQUIREMENTS
• Hand-driven galvanized roong nails are
recommended for installing trim with
nailing n.
(1-3/4" StormGuard
®
Ring shank
nails from Maze Nails are recommended).
NOT RECOMMENDED to use pneumatic
roong, or siding nail guns to install trim
with nailing n.
• When attaching siding, avoid nailing
closer than 1-1/2" from the end of
the board so the power nail does not
penetrate the nail n.
• When installing trim over up to 1" rigid
foam sheathing, be careful not to drive
nails so hard as to compress the foam
and distort the n.
OPTION 1: TRIM CLIPS & NAIL FIN TRIM
• Position the clips, tight on the sides and
bottom of the item to be trimmed out
and leave a 3/8" gap between clips and
top of item. Nail through the clips into
substrate.
• Place clips no greater than 16" o.c.
around the item. Then measure and cut
the trim to length.
• Cut trim for windows/other openings as
shown Fig. 7C.
• Place trim on wall; make
sure the edge with the kerf
and dado is faced towards
the clips. Starting at one
end of the trim align and
slide the rst clip into the
kerf side of the trim. Using a
slight up and down motion
continue rotating the trim into position
with the trim clips. Hold the trim with
nail n against the wall, level, plumb
and set it to the correct height before
nailing it. Make sure to leave a proper
gap between trim and windows shown in
Fig. A
(pg 21)
• Make sure that you do not overdrive
nails. Fasten EVERY 3RD HOLE.
• Nail head should set rmly to the face of
the n, but be careful to not overdrive to
distort or damage the surface.
• Shim at trim intersections as needed
to establish ush and tight joints. Then
apply sealant.
Figure 7c
CONTINUED ON NEXT PAGE
25 | Diamond Kote Building Products Application Guide 6.18
OPTION 2: POCKET HOLE JOINERY &
NAIL FIN TRIM
• Follow these steps to assemble the Nail
Fin Trim by screwing the trim together
using a pocket hole joinery and then
installing the trim on the wall as a
unitized frame.
• The advantage with this option is that
the trim joints will be tighter, and should
not require shimming to keep them ush.
• Joints may be assembled with either 45°
miters or butt & pass methods.
POCKET HOLE REQUIRED EQUIPMENT:
• Pocket hole jig w/drill bit
• 2" Pocket screws (exterior grade)
• Portable pocket hole jigs are readily
available from retail suppliers.
INSTALL:
• Measure and cut the trim pieces to
the proper length as normal, then
touch up paint all cut ends. Be sure to
add the proper gap amount to your
measurements.
(Fig. A)
• Please follow the tool manufactures
instructions by setting up the jig and
drill. From our experience best results
are obtained by setting the jig for 1"
material and the drill depth gauge for
¾" material using 2" screws. Because
manufactures dier, nd the settings
that work best for you. Experiment on a
test piece rst.
• Follow the hole placement diagrams
below for your situation. Drill 2 holes for
4" trim and 3 holes for 6" trim. Place the
holes from the edge of the material at
the dimensions shown for each joint to
join the material together.
Proper hole placement is important for
screw holding power. Caution: drilling too
close to the edge may cause material to
split.
• Using a scrap piece of the nail n,
approximately 2" x 3.5" (circled), will help
keep the trim clamped securely in the jig
while drilling.
(See Fig. B, C, & D)
• After all four joints are drilled begin
assembling the frame.
(Fig. E)
• Follow recommendations
from the manufacturer on
installing screws with the
trim face down. Take care
to protect the pre-nished
surface from damage during
assembly.
• With the pieces of trim
assembled, take the unitized frame
to the desired area on the wall, t the
trim frame to the opening leaving the
required gap between trim and opening.
(Fig. A) Level the trim frame and fasten
through the nailing n lling every 3rd
hole. Nail heads should set rmly to
the face of the n, but be careful to not
overdrive to distort or damage the n
surface.
• Make sure that you do not overdrive
nails. Fasten EVERY 3RD HOLE. We
recommend using 1-3/4" StormGuard
®
Ring shank nails from Maze Nails.
• Apply sealant as shown on Fig. A
• Watch the Pocket Hole Joinery Video.

TRIM & FASCIA 190, 440, 540 & 2000 SERIES
PREPARATION
• Minimum 6 inches clearance must be maintained between trim
and nished grade. (See diagram 2a)
• Trim applied adjacent to roofs, porches, patios, sidewalks, etc.
must have a clearance of at least 1 inch above any surface where
water might collect. The surface must be sloped or otherwise
designed to provide proper drainage so the trim is at no time
directly exposed to standing water. (See diagram 2b)
• A non-corrosive drip-edge must be applied at bottom edge of
roong where it meets the fascia. (See diagrams 2c and 9c)
• In a horizontal brick frieze or band board application where the
trim meets the masonry leave a 3/8 inch minimum airspace and
ash between the trim and the masonry. (See diagram 2d)
GENERAL REQUIREMENTS (CONTINUED)
• For the cleanest cut and longer blade life, a ne-tooth carbide
tipped blade is recommended.
• Trim and fascia are manufactured with a special edge coating
which reduces moisture-related issues. Do not rip and/or rout
the trim and fascia, as it will leave the edges unprotected. If the
trim or fascia materials are ripped you must take special care to
prime, paint and seal all exposed wood ber as described in the
nishing section.
• Climb cut the surface of the trim and fascia such that the rotation
of the blade cuts downward on the primed or prenished
surface.
• Do not miter trim ends or edges. 45 degree diagonal cuts of trim
ends around door and window opening is acceptable, as well as
joining. (See diagram 2e)

NAILING INSTRUCTIONS
• In braced wall assemblies, use minimum
6d hot-dip galvanized nails for 38 and
76 Series panels
(0.113 inch shank diameter,
0.270 head diameter) and minimum 8d
for 190 Series panels (0.131 inch shank
diameter, 0.290 head diameter) for 190
Series panels.
• Do not use electroplated fasteners.
• Refer to your local building code to verify
the minimum allowable fastener size.
• Penetrate structural framing or wood
structural panels and structural framing
a minimum of 1-1/2 inch.
For 76 and 190 Series panels:
• Single nailing for 76 and 190 series
meets wall bracing requirements.
• To meet the equivalent 3/8 inch shear
wall design values, double nailing
procedures must be used.
• It may be necessary to angle drive the
second nail in order to penetrate the
framing. Seal nails driven below the
surface.
• Shear values for panels applied directly
to studs shall be no greater than noted in
Table 1 of the ICC-ES Report ESR-1301
or Table 1 of APA PR-N 124.
• Not warranted for application on SIP and
ICF assemblies.
For 38 Series panels:
• Procedure is to double nail in order to
meet the wall bracing requirements and
5/16 inch shear wall design values.
CAUTION
• 38 and 76 Series panels must be
installed on 16 inch O.C. framing only.
When installing on 24 inch O.C. framing,
190 Series panels are required.
• Back of panel must not come in contact
with masonry/concrete foundation.
• Do not force siding into place.
• Maintain the illustrated 1/8 inch space
behind the joint to allow for expansion
while the panel equilibrates with the
local environment.
• LP
®
SmartSide
®
Panel siding must not
be attached by stapling.
• Install panels in light contact to the
edge of alignment bead.
(see Figure 1 and
Figure 2 far left column) Do not install over
alignment bead.
• Climb cut the surface of the siding
such that the rotation of the blade cuts
downward on the primed or pre-nished
surface.
• Where siding butts window trim, door
casings and masonry, etc. leave a 3/16
inch gap and seal.

INSULATED SHEATHINGS
• LP
®
SmartSide
®
Panel siding may be
installed over low-compression rigid
foam or exterior gypsum.
These precautions must be followed:
• Adequate bracing of the wall in
accordance with International Codes or
other ruling building code is required.
• For rigid foam sheathing up to 1 inch
(25.4 mm) thick, siding may be nailed
directly to the foam sheathing unless
a drainage plane is required by the
local building code. Nail length must be
increased to ensure a minimum 1-1/2"
(38.1 mm) fastener penetration into the
structural framing.
• For rigid foam sheathing greater than 1"
(25.4 mm), a minimum 1-1/2" (38.1 mm)
thick by 3-1/2"
(88.9 mm) wide vertical
strapping or furring strip must be
installed over the sheathing to provide
a solid, level nailing base for the siding.
The strapping must be securely fastened
to structural framing, spaced no greater
than 16" on center
(406 mm), with a
minimum nail penetration of 1-1/2" on
center
(38.1 mm) and a maximum nail
spacing no greater than the width of the
siding.
• LP

will assume no responsibility for any
damage or condition arising from the

ATTACHING TRIM AS BATTEN STRIPS
• In cases where trim/batten strips
are fastened just into the structural
sheathing, attachment will require
additional support from a construction
adhesive.
• First, secure the trim to the structure
while the construction adhesive
completely cures, using hot-dipped
galvanized ring-shanked nails no smaller
than 0.091 inch shank diameter.
• Second, use an exterior grade
construction adhesive that meets the
following specications.
Construction Adhesive Specications:
• Minimum bond strength: 300 psi
• Minimum application temperature: 40° F
• Paintable grade
INSTALLATION
• When attaching trim as batten strips,
follow the Fastening Instructions section
in this document.
• Exception: When using trim less than 3
inches wide as battens, apply only one
nail per width, a maximum of every 36
inches vertically.
• When batten strips are applied over
panel siding at vertical joints, sealant is
not required.
• When batten strips are applied to walls
with horizontal panel joints, do not run
battens over the panel joint and ashing.
Terminate the trim battens above and
below the horizontal panel joint to allow
for proper spacing and ashing.
(See
diagrams 10a and 10b)
• When batten strips are applied to walls
with horizontal band boards be sure to
properly ash above and below the band
board. Leave a minimum 3/8 inch space
between the ends of the batten strips and
the band board. Prime and paint all cut
ends and exposed substrate. Z-ashing
installed below the band board must
cover the top ends of the batten strips
below.

PREPARATION
• Minimum 6 inches clearance must be maintained between trim
and nished grade. (See diagram 2a)
• Trim applied adjacent to roofs, porches, patios, sidewalks, etc.
must have a clearance of at least 1 inch above any surface where
water might collect. The surface must be sloped or otherwise
designed to provide proper drainage so the trim is at no time
directly exposed to standing water. (See diagram 2b)
• A non-corrosive drip-edge must be applied at bottom edge of
roong where it meets the fascia. (See diagrams 2c and 9c)
• In a horizontal brick frieze or band board application where the
trim meets the masonry leave a 3/8 inch minimum airspace and
ash between the trim and the masonry. (See diagram 2d)
GENERAL REQUIREMENTS (CONTINUED)
• For the cleanest cut and longer blade life, a ne-tooth carbide
tipped blade is recommended.
• Trim and fascia are manufactured with a special edge coating
which reduces moisture-related issues. Do not rip and/or rout
the trim and fascia, as it will leave the edges unprotected. If the
trim or fascia materials are ripped you must take special care to
prime, paint and seal all exposed wood ber as described in the
nishing section.
• Climb cut the surface of the trim and fascia such that the rotation
of the blade cuts downward on the primed or prenished
surface.
• Do not miter trim ends or edges. 45 degree diagonal cuts of trim
ends around door and window opening is acceptable, as well as
joining. (See diagram 2e)

These steps show the correct procedure for
installing roof edge products to facilitate
easy installation of the LP
®
SmartSide
®
Sot and Fascia.
Depending on the
situation you will need
to use your discretion
to install Sot or Fascia
rst.
STEP 1: Hold the metal
roof edge up to the eave
edge of the roof line.
Keep the top edge of the
metal on the plane of
the sheathing, slide the
metal roof edge up or
down the roof until a 5/8"
measurement is achieved
perpendicularly out from
the Fascia to the inside
of the bend in the metal
roof edge.
Continue to hold it in this
position.
STEP 2: While in the
same position as Step 1,
mark the top edge of the
metal roof edge on the
roof sheathing.
STEP 3:
Take the distance of
the mark from Step 2
measure the edge of the
roof to the mark on the
opposite of the eave.
Snap a chalk line from
end to end for reference.
STEP 4: Install the metal
roof edge by aligning to
the chalk line and fasten.
Be sure excess material
hangs over past the ends
of the roof corners, gable
or eave intersection.
Trim the edge of the
metal roof once it is
installed on the gable
ends or around the
corners
(for hip roof lines).
STEP 5: For hip roof lines,
repeat steps 1 through
3 for the other sides of
the roof system and then
skip to Step 10.
STEP 6: Install roong
underlayment.
STEP 7: For gable ends,
hold the metal roof edge
up to the gable edge of
the roof line. Keep the top edge of the metal
roof edge on the plane of the sheathing.
Then slide the metal
roof edge in or out from
the edge of the roof until
5/8" measurement is
achieved from the fascia
to the inside of the bend
in the metal roof edge.
Continue to hold it in
this position.
STEP 8: While holding
it in position, mark the
edge of the metal roof
edge onto the roof
underlayment.
STEP 9: Measure and
then mark the distance
from the edge of the
roof at the top end of the gable and snap a
chalk line from the bottom to the top. The
metal roof edge on the eave will be trimmed
later
(Approx. 2")
STEP 10: Next trim the metal roof edge
on the eave so that it ts with the metal
roof edge going up the gable or around
the corner for hip roof lines. Leaving the
installed piece longer than necessary.
(Approx. 2") Trim AFTER the Fascia is added.
CONTINUED ON NEXT PAGE
36 | Diamond Kote Building Products Application Guide 6.18
FASCIA APPLICATION continued
STEP 11: Install the metal drip edge up the
gable end using the chalk line as a reference
and fasten. Be sure to overhang excess
material
(Approx. 2") Note: This will need
to be trimmed AFTER the LP
®
SmartSide
®
Fascia is installed.
STEP 12: Next lift up on
the metal roof edge on the
eave end and slide your
ruler up until it bumps the
top of the inside. Record
the measurement where
the bottom of the sub-
fascia ends.
STEP 13: Measure and
mark the LP
®
SmartSide
®
Fascia from Step 12 at the
recorded measurement.
It is important that this
measurement be pulled
from the dado as shown.
Rip the Fascia to width,
and use Diamond Kote
®
touch-up paint on all cut
edges.
STEP 14: Cut the fascia
to length and paint all cut
edges. Start by installing
the Fascia on the eaves.
First lift up on the metal
roof edge and slip the
Fascia behind the metal.
Make sure to fasten the
fascia every 24" o.c.
maximum. Use Diamond
Kote
®
touch-up paint on
all face nails.
STEP 15: Install the
gable end Fascia or/
other sides of a hip roof.
Finish by trimming the
excess metal roof edge o of the corners.
STEP 16: After nishing the Fascia, the next
step is adding the Sot if it is not already
installed.
SOFFIT APPLICATION
• Architectural Collection Vented Cut-To-
Width (CTW) sot provides a minimum
of 10 square inches per lineal foot of
ventilation.
• Recommended spans for open and
closed sots are given in Table 1. The
recommendations in Table 1 for open
Sots also apply to combined roof/
ceiling construction.
• Panels are assumed continuous over two
or more spans with the long dimension
or strength axis across supports for both
applications.
• In open and closed sot construction,
protect panel edges against direct
exposure to the weather with LP
®
SmartSide
®
Trim and Fascia.
• Apply the Sot in a manner that prevents
moisture intrusion and water build-up.
All openings, other than the vents, must
be sealed, caulked, and/or ashed.
• SOFFIT MUST NOT BE IN DIRECT
CONTACT WITH MASONRY, CONCRETE,
BRICK, STONE, STUCCO OR MORTAR.
INSTALLATION
• Panels must be installed perpendicular
to supports.
• Minimum size framing should be nominal
2" x 4"
• All panel edges must be supported or
backed by solid framing.
• Consult your local building code for
open sot applications.
• When installing Sot with Sot
Channel, it is highly recommended
to double up framing members at all
sot joints and seams.
