How Do You Install a James Hardie Board?

Cover the exterior surface with the appropriate material, wrap the material with a moisture barrier, mark the studs and install any necessary trim, cut and nail the boards into place then paint and caulk is how you install James Hardie board plank siding. Consult the building codes in your area as some jurisdictions may vary. James Hardie makes many home construction products for a variety of applications for any other Hardie product you must consult its installation guide for instructions.

James Hardie board plank siding is not difficult to install, but it has a much harder composition than conventional wood or vinyl siding. It requires some special tools such as polycrystalline diamond tooth circular saw blades for straight cuts, carbide jigsaw blades for holes and round corners, and fiber cement shears.

Sheath the structure's external surface with foam board, oriented strand board or plywood. Use felt wrap or house wrap to cover the sheath and provide a moisture barrier. Locate the studs, and mark them from floor to ceiling on the outside of the wrap with a chalk line.

Install the corner trim pieces first, leaving enough room for two stacked pieces of plank to fit underneath. Mount a 1 1/4 inch wide piece of Hardie board on the bottom edge of the wall to set the angle for the siding. Measure and cut the planks. Blind nail or face nail the planks by hand or with a pneumatic nail gun using stainless steel or hot-dipped galvanized nails. Use a siding gauge and level to keep the boards straight and evenly spaced.

Prime the siding and any exposed cuts with 100 percent acrylic latex paint, and caulk all trim joints. When the first two are dry, paint the siding the color you desire.
