JAMES HARDIE HARDIPLANK FIBER CEMENT SIDING

What is Blind Nail?

We do the installation of James HardiePlank Lap Siding using the blind nailing technique. The fasteners are hidden by the course above. Fasteners shall be installed between 1 in and 1-1/8 inches from the top edge and no closer than 3/8 inches from the ends of the plank.

HardiePlank lap siding may be used with fasteners approved by ICC-ES NER-405 spaced in accordance with the Wind Load Tables.

Fasteners must be corrosion-resistant, galvanized or stainless steel.

 

Pin Backs

Pinning the hardie plank down at the bottom edge is a common practice called “pin back.” It is used to correct “high nailing”, loose planks, gaps or rattling. Pinning of the butt joints with is not intended to increase wind load values, and shall be installed 3/8” from the end and between 3/4” and 1” from the bottom edge. The finish nail shall be nailed flush to the surface (not countersunk), must be corrosion resistant (e.g. galvanized or stainless) and does not provide structural support. For best aesthetics nail heads should be touched up to color match.

 

Face Nailing

Face nailing is applicable where dictated by building code, in high wind areas, and when fastening is to OSB or equivalent sheathing without penetrating into studs.

Face nailing exposes the fastener head to the elements and allows for the fastener to penetrate through two sheets of overlapped plank. Fasteners shall be installed between 3/4” and 1” from the bottom edge of the board and the head must be snug, not counter-sunk or overdriven.
