Preparation of the Wall Surface

Before installation, prepare the wall surface by ensuring it is clean, flat, and structurally sound. Remove any old siding, and seal any openings to prevent moisture intrusion. It's also essential to install a weather-resistant barrier, such as a house wrap or felt paper, to protect your home's walls.

**Installation Tips**

Install James Hardie planks using metal hangers or other approved methods as recommended by the manufacturer. Ensure you leave adequate expansion space at the top and sides of each run. Maintain a continuous course along the house's perimeter to minimize expansion gaps and improve curb appeal.

**Finishing Touches**

Once the planks are installed, seal any cut edges with James Hardie's proprietary sealant to protect against moisture intrusion and extend the life of your siding.
