How to Prep Your Home for Hardie Siding
The key to a successful installation is proper preparation. Here are the best ways to prepare your home for James Hardie siding.
Measuring and Calculating Materials
Start by measuring the exterior walls of your home to determine the amount of siding needed. Measure the height and width of each wall and multiply these dimensions to get the square footage. Add 10% to your total to account for waste and mistakes. Don’t forget to calculate the amount of trim required for corners, windows, and doors.
Safety Precautions
Working with fiber cement requires safety precautions due to the dust generated when cutting. Always wear safety glasses and a dust mask to protect your eyes and lungs. Additionally, use ear protection when operating power tools.
Removing Old Siding
Before installing Hardie board siding, remove the old siding. Use a pry bar to carefully remove the existing material, taking care not to damage the underlying structure. Dispose of the old siding properly, following local regulations.
The Installation Process: 7 Step Process
Ready to get into the details about Hardie siding installation? We’ve created a step by step guide to get you started.
1) Preparing the Surface
Ensure the exterior walls are clean and dry. Check for any damage to the sheathing or framing and repair as necessary. Install a weather-resistant barrier (house wrap) to protect against moisture. Secure it with staples or nails, ensuring there are no gaps or wrinkles.
2) Cutting Hardie Boards
Use a circular saw equipped with a fiber cement blade to cut the Hardie boards to the required lengths. Make sure to cut in a well-ventilated area to minimize dust exposure. Score the boards with a utility knife and snap them for a cleaner cut.
3) Installing the Starter Strip
Install a starter strip along the bottom of the wall to ensure the first row of siding is level. Use a chalk line to mark where the top of the starter strip will be. Secure the strip with galvanized nails or screws.
4) Installing the First Row
Begin at the bottom of the wall. Place the first row of Hardie board siding so that it overlaps the starter strip. Leave a small gap (about 1/8 inch) between the siding and the strip to allow for expansion. Use a level to ensure it is straight. Nail or screw the siding into place, hitting the studs behind the sheathing.
5) Installing Subsequent Rows
Continue installing rows of siding, overlapping each row by about 1 1/4 inches. Use a spacer to maintain a consistent gap between the rows. Stagger the joints between boards to create a more natural look. Ensure each board is level before securing it in place. Cut boards as needed to fit around windows, doors, and other obstacles.
6) Installing Trim
Install trim around windows, doors, corners, and any other edges. Use flashing tape to seal the edges of the trim and prevent moisture infiltration. Make sure the trim is securely fastened and level.
7) Sealing and Caulking
Once all the siding and trim are installed, apply a paintable exterior caulk to all joints, seams, and gaps. This will prevent water infiltration and improve the overall appearance of the siding. Allow the caulk to dry according to the manufacturer’s instructions.
5. Finishing Touches
Painting and Priming
If your Hardie board siding is not pre-primed or painted, apply a primer and two coats of exterior paint. Choose high-quality paint that is designed for fiber cement siding. Use a brush, roller, or spray gun for even coverage. Allow each coat to dry thoroughly before applying the next.
Inspecting Your Work
Take the time to inspect your work thoroughly. Look for any gaps, uneven rows, or loose boards. Make any necessary adjustments to ensure a professional finish. Check the caulking and paint for any missed spots.
Maintenance Tips
Hardie board siding is low maintenance, but regular care will extend its lifespan:
- Clean Annually: Use a garden hose or pressure washer on a low setting to remove dirt and debris.
- Inspect for Damage: Periodically check for any signs of damage or wear and repair as needed.
- Repaint as Needed: Repaint the siding every 10-15 years to maintain its appearance and protect the material.
