IMPORTANT: FAILURE TO INSTALL AND FINISH THIS PRODUCT IN ACCORDANCE WITH APPLICABLE BUILDING CODES AND JAMES HARDIE'S WRITTEN APPLICATION INSTRUCTIONS MAY LEAD TO PERSONAL INJURY, AFFECT SYSTEM PERFORMANCE, VIOLATE LOCAL BUILDING CODES, AND VOID THE PRODUCT ONLY WARRANTY.

STORAGE & HANDLING:
Store flat and keep dry prior to installation. Installing siding wet or saturated may result in shrinkage at butt joints. Carry planks on edge. Protect edges and corners from breakage. James Hardie is not responsible for damage caused by improper storage and handling of the product.

• Hardiplank® lap siding can be installed over braced wood or steel studs spaced a maximum of 24" o.c. or directly to minimum 7/16" thick OSB sheathing*. Hardiplank lap siding can also be installed over foam insulation up to 1" thick. Irregularities in framing, sheathing, and/or foam insulation can mirror through the finished application.
  
• A Weather-resistive barrier is required in accordance with local building code requirements. The weather resistive barrier must be appropriately installed with penetration and junction flashings in accordance with local building code requirements. James Hardie will assume no responsibility for water infiltration.
  
• Install James Hardie® products with a minimum 6" clearance to the finished grade on the exterior of the building or in accordance with local building codes if greater than 6" is required (fig. 3).
  
• Maintain a minimum 2" clearance between James Hardie products and roofs, decks, paths, steps and driveways (figs. 4 & 5).
  
• Maintain a 1/4" clearance between James Hardie products and horizontal flashing (fig. 6).
  
• Install kickout flashing at roof-wall junctions. (fig. 7.) Ensure gutters have end caps and do not terminate against siding and trim.
  
• Adjacent finished grade must slope away from the building in accordance with local building codes - typically a minimum of 6" in the first 10'.
  
• Do not install James Hardie products, such that they may remain in contact with standing water.

INSTALLATION:
Install a 1 1/4" starter strip to ensure a consistent plank angle (Figure 1).

Install factory finished edges together at butt joints.


For other jointing options, refer to local building code or NER 405.

*If only nailed to sheathing, plank can be a maximum 9-1/4" wide and must be face nailed at 12" o.c. with 0.091" shank x 0.221 HD x 1.5" long corrosion resistant nails.
**As required by local building code ***Apply caulk in accordance with caulk manufacturers written application instructions.

Install siding and trim products in compliance with local building code requirements for clearance between the bottom edge of the siding and the adjacent finished grade.
Maintain a minimum 2" clearance between James Hardie® products and decks, paths, steps and driveways.
At the juncture of the roof and vertical surfaces, flashing and counterflashing shall be provided per the roofing manufacturer's instructions. Provide a 2" clearance between the roofing and the bottom edge of the siding and trim.
Maintain a 1/4" clearance between the bottom of James Hardie® products and horizontal flashing. Do not caulk gap.

KICKOUT FLASHING
Because of the volume of water that can pour down a sloped roof, one of the most critical flashing details occurs where a roof intersects a sidewall. The roof must be flashed with step flashing. Where the roof terminates, install a kickout to deflect water away from the siding (figure 7).

It is best to install a full rubberized asphalt flashing on the wall before the subfascia and trim boards are nailed in place, and then come back to install the kickout.

Figure 7, Kickout Flashing To prevent water from dumping behind the siding and the end of the roof intersection, bend a small "kickout" from metal flashing to divert water running down the roof away from the siding.

  GENERAL FASTENING REQUIREMENTS
  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.

  PNEUMATIC FASTENING
  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.

  • Consult applicable code compliance report for correct fasteners type and placement to achieve specified design wind loads and shear values.
    
  • NOTE: Published shear values and 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, caulk nail hole and add a nail. (Fig. B)
    
  • Under driven nails should be hit flush to the plank with a hammer.
    
  • Do not use aluminum fasteners, staples, or clipped head nails.
  
  
  

  CUT EDGE TREATMENT
  Caulk, paint or prime all field cut edges.

  CAULKING
  For best results use a latex sealant that complies with either ASTM C834 or ASTM C920 (Grade NS Class 25). Caulking must be applied in accordance with the caulking manufacturer's written instructions.

  PAINTING
  James Hardie products must be painted.* 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.
  *within 180 days for primed product and 90 days for unprimed

  COLORPLUS® TECHNOLOGY CAULKING, TOUCH-UP & LAMINATE
  
  • Touch up nicks, scrapes and nail heads using the ColorPlus® technology touch up pen. Touch-up paint should be used sparingly. If large areas require touch-up, replace the damaged area with new Hardiplank® 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 dealer.
    
  • Treat all other non-factory cut edges using the ColorPlus technology edge coaters, available from your ColorPlus™ product dealer.
