| Kick-Out Flashing | Redirects water away from the bottom of siding panels |
Installing the Trim
Trimming is the final step in installing fiber cement siding. It helps protect your siding from the elements and provides a finished look to your home.
To install the trim, you will need:
- Trim boards
- Nails
- Caulk
- Caulk gun
Installing Corner Trim
Start by installing the corner trim. Cut the trim boards to the desired length and angle them at 45 degrees at the ends. Position the trim boards in the corners of the siding and nail them into place. Make sure the trim boards overlap the siding by at least 1 inch.
Once the corner trim is installed, you can install the other trim pieces, such as window trim, door trim, and fascia trim. Cut the trim boards to the desired length and nail them into place. Make sure to overlap the trim boards by at least 1 inch.
Once all of the trim is installed, you can caulk the seams between the trim and the siding. This will help protect the trim from water damage.

| 2 | Hold the panel firmly on a stable surface and wear appropriate safety gear. |
| 3 | Use a circular saw with a sharp blade to cut the siding panel along the marked line. |
| 4 | Align the cut edge of the siding panel with the marked starting point on the wall. |
| 5 | Drive screws into the panel through the pre-drilled holes, ensuring they are spaced evenly and countersunk into the panel. |
Overlapping and Interlocking the Panels
The interlocking system is a highly durable siding installation technique that bonds the panels for increased strength. Here’s a step-by-step guide to overlapping and interlocking fiber cement siding:
Panel Overlapping
1. Align the bottom edges of the panels, ensuring a 1/4″ overlap at the bottom course.
2. Overlap the siding panels by 1″ at the end joints, and ensure a 1/4″ overlap at the top course.
3. Install the siding panels horizontally, starting from the bottom and working upwards.
Panel Interlocking
4. Stagger the vertical joints of the panels by a minimum of 12 inches.
5. Use galvanized nails to fix the starter strip and each panel to the studs.
6. Insert the top interlocking tab of the upper panel into the bottom groove of the lower panel. Use a pry bar to gently lift the upper panel to ensure a tight interlocking fit. This provides superior stability and prevents water infiltration.
7. Secure the upper panel to the studs using galvanized nails.
8. Repeat the interlocking process for all subsequent courses.
Nailing or Screwing into Studs
The most critical step in installing fiber cement siding is ensuring it’s securely fastened to the wall studs. This can be done either by nailing or screwing the siding into place.
Nailing:
Use 8d galvanized ring-shank nails specifically designed for fiber cement siding. Drive the nails straight into the studs at a 45-degree angle, countersinking the heads slightly below the siding’s surface.
Screwing:
Use 2-1/2-inch galvanized exterior screws with a countersinking head. Drive the screws straight into the studs perpendicular to the siding surface, ensuring the heads are flush with the siding.
Spacing and Patterns:
The spacing and patterns for nailing or screwing vary depending on the siding manufacturer’s recommendations. Generally, nails should be spaced 12 inches apart on studs, while screws should be spaced 8 inches apart. The siding should be screwed or nailed into the center of the stud for maximum holding power.
Recommended Tools:
It is recommended to use a pneumatic nailer or drill with a clutch setting to ensure consistent nailing or screwing depths. Use a countersinking tool to embed the nail or screw heads below the siding’s surface.
Tips:
| Tip | Description |
|---|---|
| Use a backer rod | Insert a backer rod between the siding and any gaps around windows, doors, or other openings to prevent water infiltration. |
| Pre-drill holes | Pre-drilling holes for screws can prevent splitting or cracking the siding, especially when working with thicker panels. |
| Countersink nails or screws | Countersinking the nail or screw heads below the siding’s surface not only provides a flush appearance but also helps prevent moisture from penetrating the siding. |
