Choose Precision Series 38 Series or Foundations 76 Series soffit
for closed soffit applications and Precision Series 76 Series soffit
for open soffit applications. Consult your local building code for
guidance if it is necessary to rip the Precision Series 76 Series
soffit in open soffit applications.
Recommended spans for open and closed soffits are given in
Table 1. The recommendations in Table 1 for open soffits 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.
Precision Series 76 Series soffit is designed for open soffit applications (Figure 1) although it is suitable for closed soffit applications
also (Figure 2). Precision Series 38 Series and Foundations 76
Series soffit can be used for closed soffit only (Figure 2).
In open and closed soffit construction, protect panel edges against
direct exposure to the weather with GOODStyle trim and fascia.
Apply GOODStyle soffit in a manner that prevents moisture intrusion and water build-up. All openings, other than the vents, must
be sealed, caulked, and/or flashed.
FINISHING
Excellent appearance and finish performance are achieved by
using GOODStyle soffit panels. Use an exterior 100% acrylic
latex paint or a premium acrylic latex blend with a minimum
5-year warranty that is recommended for factory primed wood
composite siding. Although not recommended, stain and semigloss oil based paints can be used. Follow the coating manufacturer’s application and maintenance instructions. All exposed
wood substrate must be primed and painted. GOODStyle soffit
must be painted within 120-days of installation. Seal all joints
with a high-quality, paintable sealant with a stated service life
of 30 years. Follow the sealant manufacturer’s instructions for
application and backer rod requirements.
• Panels must be installed perpendicular to supports.
• Minimum size framing should be nominal 2 in. x 4 in.
• All panel edges must be supported or backed by solid
framing.
• Consult your local building code for open soffit applications.
• Space nails 6 inches at panel edges and 12 inches at
intermediate supports.
• Do not use staples.
• When installing the Architectural Collection vented
soffit, avoid cutting through the vented areas. If it cannot
be avoided, take special precautions to avoid damage to
the spokes within the vent.
• The spokes within the vent may warp slightly during
equilibration with the local environment. This condition is
temporary and the spokes will straighten.
• Factory manufactured Cut-To-Width soffit is approved for
use in closed soffit applications only.
• Field prepared Cut-To-Width soffit should comply with local
building codes.
• Space the end and edge joints 1/8 in. when using 8-foot
soffit.
• Space the end and edge joints 3/16 in. when using 16-foot
soffit.
• LP SmartSide Soffit products are not designed for and are
not suitable for use as siding or trim.

GENERAL
NAILING (CONTINUED)
• There are no National Standards for wood composite substrate trim.
• Leave 1 in. clearance between trim and roofing materials at roof rake.
• GOODStyle trim and fascia can be applied directly over materials such
as siding, or nailed directly to structural members up to 24 in. O.C.
• For edge-nailing, all nail holes must be pre-drilled. Do not attempt to
edge-nail without pre-drilling.
• Do not let trim contact masonry.
• When applied as rake, corner or band board, nails must be spaced
no further than 12 in. apart on alternating edges. Nails must be at
least 3/8 in. from the edge.
• Minimum 6 in. clearance must be maintained between trim and finish
grade.
• Trim applied adjacent to porches, patios, walks, etc. must have a
clearance of at least 3/8 in. above any surface where water might collect.
The surface must be sloped or otherwise designed to provide proper
drainage so the siding is at no time directly exposed to standing water.
• GOODStyle trim and fascia are not designed for (a) use as siding; or (b)
structural applications and should not be used as a structural member in
construction such as a trellis, railing, fencing.
• A non-corrosive drip-edge or drip-cap must be applied at bottom edge of
roofing where it meets the fascia.
• Trim and fascia must not be applied to green or crooked structural
framing members. Do not apply trim and/or fascia over rain soaked or
buckled sheathing materials.

MOISTURE
• Moisture control and moisture vapor control are critical elements of
proper housing design. Check your local building codes for application
procedures for handling moisture and moisture vapor in your area.
• Follow all applicable building code specifications 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 constant sources of moisture. Lack of proper
ventilation; exposure to repetitive sources of water such as sprinklers,
condensation, inadequate flashing; improper sealing; or failure to
follow common building practices that prevent moisture intrusion into
the wall-system; may cause damage, and will void the warranty.
FLASHING, WINDOWS, DOORS & OPENINGS
• All openings must be sealed and flashed in a manner
that prevents moisture intrusion or water buildup. Several
examples that accomplish this are shown.
• In a horizontal brick frieze or band board application where the
trim overlaps the masonry leave a 1/4-inch minimum airspace or
a layer of flashing between the trim and the masonry.

Application instructions (cont.)
Siding Applicator Instructions
a)Apply siding over properly prepared walls (see General Information) with a maximum stud spacing of 16 in. o.c.
b) Begin by nailing a starter strip (approximately 3/8 in. x
1-1/2 in.), flush with bottom edge of sill plate.
Starting from left to right, level and install the first course
of Cedar Shake Lap Siding so bottom edge is no more than
1/2 in. below the shim. Trim left edge so that siding section
fits against corner board, with a 3/16 in. gap, and so that opposite shiplap edge falls on a stud for nailing.
Use “alignment notch” in shiplap edge as automatic guide to
lap each siding course. Lap a minimum of 1-3/4 in. to bottom
of notch, as shown. Nail 3/4 in. from bottom edge to penetrate both siding courses.
c) Start subsequent courses in same manner but trim each course
to effect staggered joints. Best appearance is obtained by
trimming second course starter piece 16 in. shorter than the
first course and trimming the third course starter piece 32 in.
shorter than the first. Repeat this same sequence every three
courses.

• S
tore off the ground well supported, on a flat surface, under a
roof or separate waterproof covering
• Keep siding clean and dry. Inspect prior to application.
• Allow siding to adjust to atmospheric conditions before application.
Stud Spacing
• Precision Series 38 Series and 76 Series panel siding must be installed on 16 in. OC framing only. When installing on 24 in. OC
framing, Precision Series 190 Series panel siding is required.
• All openings must be properly sealed or flashed in a manner that
prevents moisture intrusion or buildup. Several examples that
accomplish this are shown on the following pages.
Trim
Trim should be thick enough so the siding does not extend beyond the face of the trim.
• Trim and fascia must be applied in a manner that will not allow
moisture intrusion or water buildup.
• LP® SmartSide® 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.

Nailing Instructions
Kick-Out Flashing
• Install kick-out flashing to direct the water into the gutter
• Install step flashing with minimum 4-inch upper leg
• Properly integrate flashing with the secondary water-resistive
barrier. Use housewrap, flashing tape, z-flashing, or other items as needed to maintain the counterflashing principle.
• DO NOT extend the siding or trim into the kick-out flashing or gutter
• Maintain a clearance between the end of the gutter and the adjoining
wall to allow for proper maintenance of the siding
• In braced wall assemblies, use minimum 6d (0.113 in. shank
diameter), corrosion resistant according to ASTM 641, nails for
38 Series and 76 Series panels and minimum 8d (0.131 in. shank
diameter) for 190 Series panels. Do not use electroplated fasteners. Refer to your local building code to verify the minimum
allowable fastener size.
• Penetrate studs or studs and wood sheathing a combined minimum of 1-1/2 in.

Finishing Instructions
DO
• Prime and paint all exposed surfaces including all drip
edges or where water will hang.
• Apply finish coat as soon as possible or within 180 days of application.
• High-quality acrylic latex paint, specially formulated for
use on wood and engineered wood substrates, is highly
recommended. Semi-gloss or satin finish oil or alkyd paints are
acceptable. For flat alkyd paint, please check with the coating
manufacturer for their recommendations for use on composite
wood siding.
• Follow the coating manufacturer’s application and maintenance instructions.
DO NOT USE
• Semi-transparent and transparent stains.
• Shake and shingle paints.
• Vinyl-based resin formulas such as vinyl acetate, PVA, vinyl acetate/acrylic copolymer paints.
Figure 2
Double row of nails
• For 38 Series panels, double nailing procedure meets wall bracing requirements and 5/16 in. shear wall design values.
• For 76 Series and 190 Series panels, single nailing meets wall
bracing requirements. To meet the equivalent 3/8 in. 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.
• Not warranted for application on SIP and ICF assemblies.
CAUTION
• 38 Series and 76 Series panels must be installed on 16 in. OC
framing only. When installing on 24 in. OC framing, 190 Series
panels are required.
• Backside of panel must not come in contact with masonry
foundation.
• Do not force siding into place. Maintain the illustrated 1/8 in.
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.
• DO NOT INSTALL OVER ALIGNMENT BEAD. Install panels in
light contact to the edge of alignment bead. (see above drawing)
Application instructions (cont.)
Insulated Sheathings
LP SmartSide Sidings may be installed over low-compression rigid
foam or fiberglass sheathings. The following precautions must be
followed:
1 in. Roof & Chimney Clearance
a) Adequate bracing of the wall in accordance with the International
Codes or other ruling building code is required.
b) For rigid foam sheathing up to 1" (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.
c) For rigid foam sheathing greater than 1" (25.4 mm), a minimum
1-1/2” (38.1 mm) thick by 4” (101.6 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” OC (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-Pacific will assume no responsibility for any damage or
condition arising from the use of foam sheathing.
