Preparing the Exterior Walls

Before you start installing Hardie board siding, it’s important to prepare the exterior walls of your home. This will ensure that the siding is installed correctly and will last for many years to come. Here are the steps you need to take to prepare your exterior walls:

1. Remove any existing siding or trim

If you have any existing siding or trim on your home, you will need to remove it before installing Hardie board siding. This can be done using a pry bar or a hammer and chisel. Be careful not to damage the underlying wall sheathing when removing the old siding.

If you are removing existing siding that contains asbestos, be sure to take precautions to avoid inhaling the asbestos fibers. You should wet the siding down before removing it, and wear a respirator and gloves. Dispose of the asbestos siding according to local regulations.

2. Inspect the wall sheathing

Once you have removed the old siding, you will need to inspect the wall sheathing. The wall sheathing should be in good condition and free of any damage. If the wall sheathing is damaged, you will need to repair it before installing Hardie board siding.

3. Install house wrap

House wrap is a moisture barrier that is installed on the exterior walls of a home. House wrap helps to protect the home from water damage and air infiltration. To install house wrap, simply roll it out over the wall sheathing and staple it in place. Overlap the house wrap by at least 6 inches at all seams.

4. Install furring strips

Furring strips are thin strips of wood that are installed over the house wrap. Furring strips provide a nailing surface for the Hardie board siding. To install furring strips, simply nail them to the wall sheathing with 8d nails. Space the furring strips 16 inches on center.

Installing the House Wrap

House wrap is a thin, yet effective layer of material that is installed on the exterior of your home before the siding. It serves as a protective barrier against moisture, wind, and insects, helping to keep your home dry and well-insulated.

To install house wrap, follow these steps:

Installing the Flashing

Before you start installing the siding, you’ll need to install the flashing. Flashing is a thin metal sheet that helps to protect your home from water damage. It’s important to install the flashing correctly, so take your time and follow these steps:

Step 1: Measure and Cut the Flashing

Measure the length of the area where you’ll be installing the flashing. Cut the flashing to the correct length using a pair of tin snips.

Step 2: Install the Flashing

Place the flashing over the area where you’ll be installing the siding. Use a hammer and nails to secure the flashing in place. Make sure that the flashing is flush with the edge of the siding.

Step 3: Seal the Flashing

Apply a bead of caulk around the edges of the flashing. This will help to prevent water from leaking behind the flashing. Use a putty knife to smooth out the caulk.

Type of Flashing Where to Install
Step flashing Around windows and doors
Corner flashing At the corners of your home
Drip cap flashing Above windows and doors
Valley flashing Where two roof slopes meet

Proper Nailing Techniques

To ensure a secure and professional-looking installation, it’s imperative to adhere to the proper nailing techniques. Always use galvanized or stainless steel nails specifically designed for fiber cement siding, such as Hardie Board.

Nail Placement

Nails should be driven straight into the studs or blocking behind the siding, not through the joints or into the face of the board. Maintain a consistent 1/8-inch (3mm) gap between the nails and the edge of the siding.

Nail Penetration

To achieve optimal holding power, nails should be driven flush with the surface of the siding. Overdriven nails can cause the board to crack or split, while underdriven nails could result in loose siding.

Nail Length

The appropriate nail length varies depending on the siding thickness and the stud behind it. Typically, nails should be 1 1/4 inches long for 5/16-inch siding and 1 3/4 inches long for 7/16-inch siding. Where studs are 16 inches on center, use a 2 1/4-inch nail. For 24-inch on-center studs, opt for a 2 3/4-inch nail.

By following these nailing techniques, you can ensure a sturdy and aesthetically pleasing Hardie Board siding installation.

Applying the Hardie Board Siding

Once all the preparation work is complete, it’s time to start applying the siding. The process is relatively straightforward, but there are a few things to keep in mind.

Start at the Bottom

The first step is to start at the bottom of the wall and work your way up. This will help ensure the siding is installed evenly and correctly.

Use a Level

As you apply the siding, be sure to use a level to make sure each piece is installed straight. This will help prevent any gaps or uneven edges.

Overlap the Siding

When installing the siding, be sure to overlap each piece by about 1 inch. This will help prevent water from seeping behind the siding and damaging the wall.

Nail the Siding

To secure the siding, use galvanized nails that are at least 1 1/2 inches long. Drive the nails through the siding and into the studs. Be sure to countersink the nails so they are flush with the surface of the siding.

Caulk the Joints

Once the siding is installed, be sure to caulk the joints between the pieces. This will help prevent water from seeping behind the siding and damaging the wall. Use a caulk that is specifically designed for exterior use.
