Preparing for Hardie Board Siding Installation

Siding installation process

Before diving into the installation process, it’s essential to properly prepare the area for your new Hardie Board siding. We need to take off the existing siding. We also have to caulk and flash around windows and doors, plus trimming the sheathing.

  • a workbench
  • circular saw or miter saw
  • dust collector
  • siding gauge
  • fiber cement circular saw blade
  • siding nailer
  • 15 gauge trim nailer

Safety First: Handling Fiber Cement

Safety is paramount when working with fiber cement. Before you begin, make sure you have the appropriate personal protective equipment, such as safety glasses, cut-resistant gloves, and a respirator when cutting and drilling the sheets.

Additionally, use wet cutting and drilling or dust extraction equipment to control dust and minimize the risk of respiratory issues such as silicosis.

Assessing and Prepping the Area

Once you’ve gathered your tools and protective gear, it’s time to assess and prepare the installation area. Start by removing any nails or staples from the existing siding before installing your James Hardie fiber cement siding.

When replacing old siding, always wear a mask, gloves, and a long sleeve shirt, as some older siding materials may contain asbestos, which is toxic.

  1. Measure from the chalk line to the top of the siding.
  2. Add 1/8 inch to the measurement.
  3. Notch the siding accordingly, leaving a 1/8-inch gap between the siding and the window trim and sill.
