1.1 Receipt and storage of material on
site
Good practices pose exterior wood coating lies begin with a
reception and proper storage of equipment. Upon receipt, an
inspection is required. The customer must ensure that the product
corresponds well sponds to the model, color and quantity ordered. If
the coating is delivered damaged, it should not be installed. The
alteration of the packaging should get your attention. When a
problem is found, it must immediately contact the supplier. The
manufacturer or supplier of coating is usually not required to replace
a damaged coating once it has been installed or altered in any way
whatsoever.
It is recommended to proceed as quickly as possible to install the
siding after its receipt in order to prevent the risk of variation in
moisture content of the product, which would result in warping
boards or varying dimensions. Optimum storage conditions are your
best ally to maintain the quality and stability of your siding, and, of
receiving up his pose.
The coating must be stored in a location where it will retain its initial
state, i.e. a dry and ventilated space, unheated, on a flat, dry surface
and at a distance of 6 inches (15 cm) from the floor to allow
ventilation under the package ( Figure 1).ventilation under the package ( Figure 1).
The perfect example is a carport with sides open or gazebo. When
such a place is available, the package can remain open during the
work. Otherwise, keep permanently the fabric supplied by the
manufacturer on the package, provided that it retains its sealing,
otherwise it must be replaced by an equivalent new canvas. It is also
required to keep the plas- tic film between the boards to prevent
them from sticking on each other. Whether or not in a suitable
shelter, the coating remaining end of the day must be protected and
at least covered with the canvas provided by the manufacturer.

1.3 Recovery and fixes to the wall
To ensure proper installation, the wall covering must have a good
general flatness. Important differences in flatness between two or
more adjacent furs deform the wall covering and the resulting waves
will sometimes facili- LEMENT visible depending on the incidence of
light. Important waves also risk too compelling fastening systems to
maintain the liner in place. Corrections are recommended when the
wobble amplitude is exceeded 5 mm (0.2 in) of a fur from the two
adjacent furs ( Figure 2).adjacent furs ( Figure 2).
The installer must check that the flashing and the front weathering
are present, they are installed in accordance with applicable codes
and the installation meets the requirements of the manufacturer.
Recall that the purpose of the weather barrier and flashing is to
discharge water to the outside. A failure may cause water infiltration
and premature deterioration of the wall. Flashing seal the building
between two different types of components. The installer must
ensure that the necessary flashings are made properly ( Figure 3) according ensure that the necessary flashings are made properly ( Figure 3) according ensure that the necessary flashings are made properly ( Figure 3) according
to the codes and standards, and are present at the following
appropriate places:

1.4 Furs
For proper maintenance of a laughing exté- solid wood coating, it is
important to put in place the necessary furs. The size of the fur, their
arrangement and their spacing depend principally used the coating
profile (width, thickness) and the orientation of the surround strips
(horizontal, vertical, diagonal). When it comes to remodeling, it is
required to replace the furs place if they are damaged, in whole or in
part as appropriate.
1.4.1 Types of Fur
The furs are commonly used in wood: pine slats, jack pine, spruce
(SPF) or marine grade plywood of the same size. The coating is then
nailed or stapled to the fur. In some commercial or institutional
facilities tional, metal fur, for example, galvanized steel, Z-profile or
Omega, are sometimes used. In this case, it is required to add a
background wooden nailing as described above.
1.4.2 Dimensions and arrangement of
fur
In residential and commercial construction, the pro- rure commonly
used is 25 mm (1 inch) x 76 mm (3 in) on the market. Some
conditions are more severe than others and neces- sitent a thicker or
wider nailing base, for example, in the presence of large profiles,
dark shades and / or highly exposed to the sun faces.
All furs must be securely fixed to the building structure. So that the
cavity is drained and ventilated effectively, only the vertical strapping
are accepted directly on the weather barrier to 407 mm (16 inches)
(center to center). The best practices are therefore to install furs as
the main installation methods presented the following figures.

1.4.3 Surface coating over 6 meters high
The dimensions and spacing of the pre- sented above furs prevail for
the walls of a maximum tor heights of 6 meters. If the coating plan
area exceeds this height, to ensure effective ventilation must:
• Or further increase the thickness of rures pro- and opening at
the top and bottom walls;
• Or compartmentalize, interrupting and expul- sant the air
space by integrating new openings and air outlets in each
wall section (up to 6 meters). Refer to Figure 16 to see the
impact on the pro- rures the cutoff of the air gap at the
second floor.
1.4.4 Fixing fur
The furs must be securely fastened to the wall ossa- ture. It is
recommended that the fixing nètre pe- solid frame of at least 32 mm
(1 ¼ inch) deep. According to the manufacture of the wall and the
existing energy efficiency standard for the building envelope, it is
now common for adding insulation on the outside walls. Fastener
lengths must be adjusted accordingly so that they penetrate at least
32 mm (1 ¼ inches) in the backbone.
The type recommended fixing is twisted nail retsina. Two (2) studs
are installed furs bits then a nail (1) every 304 mm (12 inches) of
vertical space. For installation modes that require dual lathing,
second in furs requires two (2) nails to fur pieces and also two (2)
nails every fur in the front row (16 inches - 407 mm).

1.4.5 Characteristics of the facility
When the outside of the wall is flush with the foundation, it is
recommended that the furs re- cover the foundation of at least 25
mm (1 inch). If the wall is recessed relative to the foundation, or
when there masonry wall base, refer to Figure 12 and 15 for the design when there masonry wall base, refer to Figure 12 and 15 for the design when there masonry wall base, refer to Figure 12 and 15 for the design when there masonry wall base, refer to Figure 12 and 15 for the design when there masonry wall base, refer to Figure 12 and 15 for the design
recommendation mendations.
1.4.6 Protective barriers
The presence fur allows the creation of a ventilated cavity between
the wall and the coating. The pres- ence of this cavity, or air knife is
essential because it allows the discharge of water, moisture and heat
that could otherwise accumulate there. Thus, it is essential to open
this cavity, the top and bottom walls as well as openings, to ensure a
good air circulation in the cavity. These openings must at all times
remain free of caulk or other material obstructing the air flow.
The F42 functional statement of the National Building Code (NBC)
stipulates that the building must resist the intrusion of harmful
animals and insects (NRC,
2012). Thus, it is recommended to install, bottom and top walls,
ventilation components (molding, fly, etc.) to prevent rodents and
insects to lodge lies behind the coating (anti-fence rodent or metal
screen) ( Figure 7). Some manufacturers offer metal moldings that screen) ( Figure 7). Some manufacturers offer metal moldings that screen) ( Figure 7). Some manufacturers offer metal moldings that
offer this protection. NOTES:
• Avoid installing a horizontal fur at the bottom and top of the
wall, as it will prevent proper ventilation and free drainage.
• To meet Code requirements, it must also prevent the air layer

So that ventilation is optimal, the rear cavity must have minimum
dimensions. It is generally recommended that the open area of the
rear cavity is at least 10 mm ( 3/8 in). The size and position dis- fur and rear cavity is at least 10 mm ( 3/8 in). The size and position dis- fur and rear cavity is at least 10 mm ( 3/8 in). The size and position dis- fur and
the percentage of aeration tion of the installed ventilation component
(molding, fly, etc.) determines that dimension.
1.5 Outline of the openings
Before installing the fur and / or moldings to the contours of the
openings (doors, windows, conduits, etc.), it is necessary to ensure
the continuity of the tightness of the weather barrier membrane to
block the infiltration of water in the wall structure. Second, we must
ask metal flashing on top of all windows and doors to put per-
dripping water. The weather barrier should overlap the flashing 2 in.
Fur must leave a gap of about 25 mm (1 inch) above the horizontal
portion of the flashing so as to not be visible once the covering
installed. then installs the fur making sure not to press directly on the
framing of the opening date to allow water drainage and easy
installation or replacement of openness. Figure 8):installation or replacement of openness. Figure 8):
• 25 mm (1 inch) above the opening, either above the
flashing
• 12 mm (½ inch) on the sides of the opening
• 12 mm (½ inch) below the opening

1.6 Junctions with other coatings
It regularly happens that the walls of a house are covered by more
than one type of coating. It is not uncommon for example a solid
wood coating is accompanied by a low wall masonry, screwed stone
or imitation stone. The principles to be observed here are set up
flashing necessary for water drainage and to arrange an opening
above the flashings for ventilation and drainage. At the junction of
two coatings, the clearance between the coating and the flashing will
be, depending on the width of the projecting member, minimally 10
mm ( 3/8 in). For elements projecting large widths, the spacing may be mm ( 3/8 in). For elements projecting large widths, the spacing may be mm ( 3/8 in). For elements projecting large widths, the spacing may be
increased to 25 mm (1 inch).
1.6.1 masonry Muret
Generally, a stone sill is installed above a masonry wall. We must
then ask for flashing dripping water. The top of the flashing should be
under the weather barrier and under the furs. Fur must leave a space
of 38 mm (1 ½ inches) above the horizontal portion of the flashing. In
this case, the flashing just sit on the sill and caulking is applied to
prevent water seepage under the flashing. Depending on the
thickness of the masonry, a clearance of 10 mm ( 3/8 inches) to 25 mm thickness of the masonry, a clearance of 10 mm ( 3/8 inches) to 25 mm thickness of the masonry, a clearance of 10 mm ( 3/8 inches) to 25 mm
(1 inch) between the covering and the flashing will be retained. To
encourage good ventilation and good drainage, wood should not be
in contact with the flat surface of the flashing. Therefore, no caulking
should be applied to the junction between the flashing and wood
siding.

2.1 Clearances
Exterior wood coating must meet the following minimum distances to
the underlying surface to avoid deterioration in the presence of
moisture or water in the vicinity:
• 203 mm (8 inches) from the ground
• 51 mm (2 inches) relative to an inclined roof covering
• 203 mm (8 inches) in relation to a flat roofing
• 51 mm (2 in) compared to a patio
• 25 mm (1 inch) compared to tablets In situations where it is
difficult to meet these clearances, the responsibility tor returns to the
conceptual or building contractor to adapt the design and installation
to achieve the same objective by other means.
2.2 ventilation openings
2.2.1 Openings for conversion
As described above, the best practice recommends setting up
openings in the top and bottom walls, which openings communicate
directly with the back cavity. These openings are crucial for draining
water, moisture and heat which could accumulate behind the coating.
On a foundation wall, which is normally aligned on the wall, this
openness does not apply because the cavity is directly exposed. By
cons, if the foundation protrudes from the wall outwardly, a flashing
must be installed and an aperture of 10 mm ( 3/8 inches) should be must be installed and an aperture of 10 mm ( 3/8 inches) should be must be installed and an aperture of 10 mm ( 3/8 inches) should be
established between the coating and the flashing ( Figure 13).established between the coating and the flashing ( Figure 13).

2.2.2 Open area of the rear cavity of
the coating
The open area of the rear cavity depends on the thick- ness of the
fur, the spacing of furs and ventilation of the ventilation component
(move- lure, fly, etc.). Components of ventila- tion whose perforations
(quantities and dimensions) allow free passage of air and which are
equivalent to a free space open for a minimum of 10 mm ( 3/8 in) equivalent to a free space open for a minimum of 10 mm ( 3/8 in) equivalent to a free space open for a minimum of 10 mm ( 3/8 in)

open area for the majority of situations batten walls. These vertures

that could affect the passage of air.
2.3 Arrangement of lengths and butt joints
To achieve a natural effect and distribute the effects of shrinkage or
longitudinal expansion potential, it is preferable to vary the board
lengths and distributing the butt joints on the wall to prevent them
from being aligned. We must therefore plan the distri- bution lengths
on the wall as follows:
• Distribute the boards so as to limit the number of
joints on the wall
• Placing the lengths depending on the length of the spaces to
be covered to minimize the number of cuts
• Whenever possible, avoid seals over the openings to limit the
potential seepage points

• It is recommended to insert shorter lengths between the
long boards
• A vertical transition molding, wood or metal, is necessary if
it is desired to make wall sections fixed lengths
Layout of non tongue and groove cladding
In the case of coating not tongue and groove, it is required to align
the seals on the fur in order to firmly secure the ends of the surround
strips against each other.
Tongue and groove arrangement of the coating (seal
arrangement lost)
Many manufacturers now offer coating plates whose ends are
profiled groove and tongue (tongue and groove). This maximizes the
use of wood and lengths in an assembly called "joint Lost" and
facilitates the random distribution of butt joints on the wall.
2.4 Cups
2.4.1 How to make the cuts
For a quality cut, use a finishing blade. Regular cutting blades tend to
perform non smooth rough cuts.
Cup abutment:
It is recommended to make butting cuts angle of 22.5 °, compared
with a 90 ° cut, made for a higher quality and to avoid seeing through
the joint event shrinkage of wood. The angle of 22.5 ° is suggested to
prevent fraying or breakage after the cut, with respect to a 45 ° cut. It
is not necessary to provide a space, because the tips must be
supported on each other.
In the case of parts installed vertically, moldings, coatings, etc., it is
imperative to make a cut with an angle favoring the drainage of water
outwardly.
In the case of parts laid horizontally, it is suggested to make a cut
with an angle will be directed to the least visible side of the building.
As will be specified in section 2.5, it is important to apply a finishing
product to the ends of the parts before installation.
junction Cup:
When a cut should be made to define an area or an opening, it is
recommended to make 90 ° angle cuts while providing a clearance of
about 3 mm ( 1/8 inches) in length to allow movement of the wood. about 3 mm ( 1/8 inches) in length to allow movement of the wood. about 3 mm ( 1/8 inches) in length to allow movement of the wood.

2.4.2 Defects removed before installing
The wood contains character brands that enhance its aesthetic
value. It is in the light of these characteristics a pre Repair work is
done in the factory, following strict quality and well detailed criteria to
remove the deficiencies which may let in water in the coating.
Despite this, some anomalies can be found in the final product.
Additionally, transportation and handling can cause breakage.
Therefore, it is the customer or installer to provide a percentage loss
for any mate- riau to cut, and make a final check of the boards prior
to installation. On the other hand, it may happen that a customer or
installer wants to remove some brands of character, in whole or in
part, for a more consistent, streamlined.
2.5 Alterations
2.5.1 Why and how do retouching
During installation, alteration of surface finish, such as cuts or laying
bindings, can cause water infiltration and degrade the product.
Wherever wood is exposed, it must be protected against potential
damage by reapplying sufficient quantity of the finishing product. The
goal of retouching is to seal the exposed parts must finish using the
product supplied or recommended by the manufacturer. minimally
must apply a layer of quan- tity sufficient to saturate the pores. A
second layer may be desirable in some cases. The alterations must
be made using a pin- CWater or size applicator comparable to
retouching to perform. It is important not to reapply product
retouching over the finish up for not altering the appearance. For
example, during an apparent rents nails installation, the head of the
bare nails must be touched to the tip of the brush without overflowing
the woods around.
2.5.2 Application conditions
As the purpose of retouching is to seal parts of bare wood, it is
essential that the conditions allow the product to penetrate the wood.
For this, the wood and finishing product must be at a suitable
temperature such that the viscosity of the finished product is optimal.
In this, the coating manufacturers refer to their manufacture cant
finishing products and it is usually a temperature above 10 ° C.

When two layers are required, it is necessary that the first coat to dry
before applying the second, unless otherwise specified by the
manufacturer of the finishing product.
It is important to protect the product against freezing retouching
before and during use to avoid changing its properties.

However, some fasteners may be dissimu- Lées when laying a
coating without visible fixings: coating plates whose interlocking sys-
tem has been cut or where the stapler can not access. The highlight
described above provided by the manufacturer can be used in
particular in the following situations:
• Starter Course at the bottom of the wall
• coating board above an opening (window or door)
• coating board under a window
• Coverboard coating the top of the wall
2.6.2 anchorage depth
Article 9.27.5.7.2) of the National Building Code (NRC, 2015) states
that for optimum performance of the coating, fasteners must cross
furs or penetrate at least 25 mm (1 in) in a solid backing. This nailing
base may be composed of a combination of a fur and solid wood
(OSB, plywood, CLT). Calculating the depth of penetration into the
backing to consider the thickness of the coating installed and the
angle of incidence.
For the majority of 19 mm coverings ( 3/4 inch) thick or less, a staple of For the majority of 19 mm coverings ( 3/4 inch) thick or less, a staple of For the majority of 19 mm coverings ( 3/4 inch) thick or less, a staple of
51 mm (2 inches) in length, placed at an incident angle between 20
and 30 degrees will pass through the fur as specified in the National
Building Code of Canada (NRC, 2015) . Similarly, insertion of a nail
of 51 mm (2 inches) in length at a right angle (90 degrees) on a
coating of varying thickness lies between 19 and 25 mm ( 3/4 and 1 coating of varying thickness lies between 19 and 25 mm ( 3/4 and 1 coating of varying thickness lies between 19 and 25 mm ( 3/4 and 1

2.6.3 Positioning of fasteners
Coating with no visible fasteners
For coating with no visible fasteners, the bottom boards is
maintained by fitting in the plate beneath. By against the top of the
board to be fixed with two fasteners by fur. To this end, many
manufacturers indicate a staple line on their profiles. If this line is not
present, the clip should be positioned to be covered by the board

Exposed fasteners coating (head nails)
The coating exposed fasteners whose width varies between 100 and
152 mm (4 and 6 inches) must be nailed to about 25 mm (1 inch)
from the bottom of the surround strips comprised of one fastener (1
nail) by fur. The highlight has to pass through the coating in its full
thickness and be far enough from the lower lip to prevent its bursting.
When the coating has a width of 203 mm (8 inches) and a second
fixation is minimally required. So there are two nails to a minimum by
ironing on each fur.
Refer to manufacturer installation guide for details on the number
and positioning of attachments for different types of profiles.
For molding, only one point of attachment is recommended for widths
less than 51 mm (2 inches), while two attachment points are required
for widths greater than 51 mm (2 inches), each point being located at
about 19 mm ( 3/4 inches) from the shore. Ideally, for all widths, the about 19 mm ( 3/4 inches) from the shore. Ideally, for all widths, the about 19 mm ( 3/4 inches) from the shore. Ideally, for all widths, the
fastening points are spaced 407 mm (16 inches) or less.
For optimum performance of the coating, it is important to follow
these instructions:
• Penetration of the head (or crown) The head nails or staples
wheelbase is well rely on wood and does not penetrate the surface,
because the perforation becomes a water infiltration point and
weakens the holding of the board.
• While supporting the coating plate before fixing.
• Avoid stapling or nailing too close to the banks to prevent the
wood broke.
• Sometimes it is ideal for coating pre-drill to fasten the
boards when the binding is too close to the shore or end.

24- Perform edits and apply caulk
where appropriate (sections 3.5 and 3.8)
2.8 Caulk
2.8.1 Role caulking
To limit the risk of water penetration, a felting cal- must be used.
Caulking intervenes the first protection plan of the principle of rain
screen in combination with the coating itself, to intercept any
potential water infiltration.
2.8.2 Location caulk
The caulk should be applied with caution to all places where water
could penetrate. This is the case along a vertical joint in the meeting
of revê- ment with the beads (door sides, window sides, corners).
Remember that proper installation of flashing over openings requires
no caulking. Proper flashing, installed, block potential infiltration. It
must, however, provide a spacing of 10 mm (3/8 inch) between the
coating and the base of the flashing to ensure good ventilation. By
cons if the horizontal overlap of the flashing does not extend beyond
the underlying element, it is then necessary to apply a joint caulking
to prevent the penetration of water infiltrated under the flashing. See
the example of masonry wall in section 1.7.
Installation Best Practices Guide external facing solid wood
Short version22
2.8.3 Choice of caulking
A multitude of caulking products on the market. This guide refers to
the section 9.27.4.2 of the NBC for specifications caulk (NRC,
2015). Generally, the caulk should be:
• Non-hardening (flexible) for outdoor use
• Selected for its resistance to the effects of erosion
• Compatible with and adhering the wood and the finish of the
coating
• No or very low volatile organic compound (VOC)
2.8.4 Application of Caulk
Always follow the manufacturer's recommendations for caulking to
the application. The caulking cord must adhere well to both surfaces
that create the opening. For openings larger than 6 mm ( 1/4 inch), it is that create the opening. For openings larger than 6 mm ( 1/4 inch), it is that create the opening. For openings larger than 6 mm ( 1/4 inch), it is
recommended to first install a filler into the opening and then covered
with felting cal-. The caulking must also always be placed between
two parallel surfaces and not perpendicular. The caulk is not a
permanent solution and requires regular maintenance. If they are not
inspected and maintained regularly, the caulking joints may fail,
capture the water and alter the surface or even generate more
serious problems of mold and rot in the wall structure.
Installation Best Practices Guide external facing solid wood
Short version 23 Short version 23
It is advisable to conduct a regular and preventive maintenance of
siding to preserve its original appearance, prevent its degradation
and ensure the longevity of the wood. An an- nual audit will check
the condition of the coating and caulking joints.
3.1 Cleaning
An annual washing is recommended to dislodge the accumulation of
dirt (mold, dirt, cobwebs, etc.). The coating can be simply cleaned
with a low pressure garden hose and a soft brush of the same type
for the washing of a body of automo- bile. You can also add a mild
cleaning agent, without bleach, ammonia or abrasive element. If
necessary, the cleaner can be tested on a small area to make sure it
will not damage the coating. After washing, it is recommended to
gently rinse with a low pressure hose. NOTE: The pressure washer
is prohibited. Some wood species may be conducive to sap flow
following exposure of the coating to the hot summer temperatures.
To eliminate it, sap must be drybrushed when dry with a simple
non-metallic brush. The white powder produced by brushing can be
rinsed with water using a low-pressure hose. This sap cleaning
procedure can be repeated as needed if the additional sap flows
from the coating after a few seasonal cycles. This may require minor
corrections.
3.2 Minor fixes
Immediately after installation of the coating and annually thereafter. It is highly advisable to
conduct a visual inspection of the surfaces to correct the areas affected by a scratch or a
burst resulting from an impact. On any surface revealing bare wood, apply a finishing
product provided by the manufacturer, taking care to limit its application to the simple bare
area in order not to change the color of the coating. A cotton swab or a fine brush allows
you to run applications fine. See also to apply the product retouching according to the
conditions specified by the manufacturer (p. Eg., Outside temperature during application,
drying time before the second application, etc.). Minor corrections are needed to the
season following scratches or shocks for various reasons (bicycle leaning on the siding,
stone thrown by the snow blower, etc.). Visual examination is still advisable to make the
required corrections following the recommendations outlined above for touch. However, be
aware that the color of the coating can fade over time. If caulk seal requires correction,
must be removed cleanly without damaging the finished sur- face. In such a case, we must
touch up bare spots before reapplying a new bead of caulk. Visual examination is still
advisable to make the required corrections following the recommendations outlined above
for touch. However, be aware that the color of the coating can fade over time. If caulk seal
