What Are Some Tips for Installing HardiPlank Siding?


Quick Answer

Some tips for installing HardiPlank siding include cutting the planks accurately in a well-ventilated place, attaching the first plank at the lowest point on the house's side, and using a side gauge to ensure correct plank alignment. In addition, use nails to attach the siding, allow the planks to overlap one another, and ensure that the nails are positioned at least 3/4 inches from the plank's top edge.

When installing HardiPlank siding, secure the planks to a pair of saw horses, and cut with a carbide-bladed power drill. Before attaching the first plank, install a 1/4- to 1 1/4-inch lath or starter strip just above the trim of the water table.

Use 11-gauge roofing nails, and shoot them into the planks with a nail gun to attach the siding. Do not use staples for plank installation. Preferably, position the nails 1 1/8 inches from the plank's top edge. Allow the planks to overlap one another by 1 1/2 inches.

Install one plank in each row. If more than one plank is required in a row, push their ends together tightly on a stud, position a joint flashing beneath the joint, and allow it to run 3 inches on either side. Recheck plank alignment every four or five rows using the siding gauge.

When installing the siding around trim and windows, maintain a gap of at least 1/8 inches to account for expansion, and caulk the gap. Do not install the HardiPlank siding in those areas where it may be exposed to stagnant water.
