PNEUMATIC FASTENING
GENERAL FASTENING REQUIREMENTS
HS11119-P3/4 05/16
James Hardie products can be hand nailed or fastened with a pneumatic tool.
Pneumatic fastening is highly recommended. Set air pressure so that the
fastener is driven snug with the surface of the siding. A flush mount
attachment on the pneumatic tool is recommended. This will help control the
depth the nail is driven. If setting the nail depth proves difficult, choose a
setting that under drives the nail. (Drive under driven nails snug with a
smooth faced hammer - Does not apply for installation to steel framing).
DO NOT use stain, oil/alkyd base paint, or powder coating on James Hardie
®
Products. James Hardie products must be painted within 180 days for primed
product and 90 days for unprimed. 100% acrylic topcoats are recommended.
Do not paint when wet. For application rates refer to paint manufacturers
specifications. Back-rolling is recommended if the siding is sprayed.
• Care should be taken when handling and cutting James Hardie® ColorPlus® products. During installation use a wet soft cloth or soft brush to gently wipe off any
residue or construction dust left on the product, then rinse with a garden hose.
• Touch up nicks, scrapes and nail heads using the ColorPlus
®
Technology touch-up applicator. Touch-up should be used sparingly.
If large areas require touch-up, replace the damaged area with new HardiePlank
®
lap siding with ColorPlus Technology.
• Laminate sheet must be removed immediately after installation of each course.
• Terminate non-factory cut edges into trim where possible, and caulk. Color matched caulks are available from your ColorPlus
®
product dealer.
• Treat all other non-factory cut edges using the ColorPlus Technology edge coaters, available from your ColorPlus product dealer.

TECHNOLOGY
When repainting ColorPlus products, James Hardie recommends the following regarding surface preparation and topcoat application:
• Ensure the surface is clean, dry, and free of any dust, dirt, or mildew
• Repriming is normally not necessary
• 100% acrylic topcoats are recommended
• DO NOT use stain, oil/alkyd base paint, or powder coating on James Hardie
®
Products.
• Apply finish coat in accordance with paint manufacturers written instructions regarding coverage, application methods, and application temperature
• DO NOT caulk nail heads when using ColorPlus products, refer to the ColorPlus touch-up section
Fasteners must be corrosion resistant, galvanized, or stainless steel.
Electro-galvanized are acceptable but may exhibit premature corrosion.
James Hardie recommends the use of quality, hot-dipped galvanized nails.
James Hardie is not responsible for the corrosion resistance of fasteners.
Stainless steel fasteners are recommended when installing James Hardie
®
products near the ocean, large bodies of water, or in very humid climates.
Manufacturers of ACQ and CA preservative-treated wood recommend spacer
materials or other physical barriers to prevent direct contact of ACQ or CA
preservative-treated wood and aluminum products. Fasteners used to attach
HardieTrim Tabs to preservative-treated wood shall be of hot dipped
zinc-coated galvanized steel or stainless steel and in accordance to 2009 IRC
R317.3 or 2009 IBC 2304.9.5.
• Consult applicable product evaluation or listing for correct fasteners type
and placement to achieve specified design wind loads.
• NOTE: Published wind loads may not be applicable to all areas where Local
Building Codes have specific jurisdiction. Consult James Hardie Technical
Services if you are unsure of applicable compliance documentation.
• Drive fasteners perpendicular to siding and framing.
• Fastener heads should fit snug against siding (no air space). (fig. A )
• Do not over-drive nail heads or drive nails at an angle.
• If nail is countersunk, fill nail hole and add a nail. (fig. B)
• For wood framing, under driven nails should be hit flush to the plank with a
hammer (For steel framing, remove and replace nail).
• NOTE: Whenever a structural member is present, HardiePlank should be
fastened with even spacing to the structural member. The tables allowing
direct to OSB or plywood should only be used when traditional framing is
not available.
• Do not use aluminum fasteners, staples, or clipped head nails.
For best results use an Elastomeric Joint Sealant complying with ASTM C920
Grade NS, Class 25 or higher or a Latex Joint Sealant complying with ASTM
C834. Caulking/Sealant must be applied in accordance with the
caulking/sealant manufacturer’s written instructions. Note: OSI Quad as well
as some other caulking manufacturers do not allow tooling.
