51 The first course of HardiePlank® siding is critical to the proper installation of the plank on the rest of the building. The first course should start at the lowest point of the house. Special attention should be made to ensure that it’s straight and level. Attention should also be paid to staggering any butt joints in the planks so that the installation is attractive while making efficient use of material. Use a level (4-ft. or longer) or chalked level line to be sure that the first course is level. As installation proceeds up the wall, periodically check the level and straightness of the...

52 Installation of HardiePlank® Lap Siding blind nailing (nailing through top of plank) In most cases, blind nailing is recommended for installing any type of HardiePlank® lap siding including ColorPlus® siding.

For blind nailing HardiePlank lap siding, James Hardie recommends driving fasteners 28mm (11/8 in.) from the top edge of the plank. Additionally fasteners should be placed no closer than 9.5mm (3/8 in.) from the ends of the plank. Avoid placing fasteners near the top...

55 Siding gable walls can be challenging, and some of the keys to siding gable walls efficiently are determining the angle or pitch of the roof, properly staging materials and ensuring that the plank lengths are measured accurately. To estimate the amount of siding needed to complete a gable end, use the estimating tools located in Appendix B. Stage enough material on the pump jacks or scaffolding to complete the gable end, but take care not to overload the staging. When possible, a cut table should be located on the pump jacks or scaffolding, which frees up crew members to work on other walls....
