PNEUMATIC FASTENING
GENERAL FASTENING REQUIREMENTS
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
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 preserva-
tive-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).
• 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.
CUT EDGE TREATMENT
Caulk, paint or prime all field cut edges. James Hardie touch-up kits are required to
touch-up ColorPlus products.
CAULKING
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: some caulking manufacturers do not allow "tooling".
PAINTING
DO NOT use stain, oil/alkyd base paint, or powder coating on James Hardie
®
products. Factory-primed James Hardie products must be painted within 180 days of installation.
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.

no closer than 1 in. from plank ends and 3/4 in. from plank edge into min. 3/8 in. wood structural panel. Pin-backs are not a substitute for blind or face nailing.
