What is Hardie Board?
Hardie Board, often referred to as fiber cement siding, is a durable, versatile material used in exterior home construction and remodeling projects. Made from a blend of cement, sand, and cellulose fibers, Hardie Board is extremely resistant to fire, moisture, and pests. Its durability and low maintenance make it a popular choice for siding, soffits, trim, and even flooring underlayment.
⭐️ Benefits of Using Hardie Board ⭐️
- Durability: Hardie Board can withstand extreme weather conditions, including hurricanes and hail.
- Fire Resistance: It is non-combustible and offers excellent protection against fire.
- Pest Resistance: Unlike wood, Hardie Board is not susceptible to termites and other pests.
- Low Maintenance: Requires less maintenance compared to wood siding.
- Aesthetic Versatility: Available in a variety of textures and styles to mimic the look of wood, stucco, or even brick.
Understanding these benefits is crucial before you start cutting, as it gives you a better appreciation for the material you’re working with.

A 5 Step Guide to Cutting Hardie Board
Follow this professional guide to cut your fiber cement board correctly, every time.
Step 1: Measure and Mark
Use a tape measure to determine the dimensions you need. Double-check your measurements to avoid mistakes.
Use a pencil and straight edge to draw a clear cutting line on the Hardie Board. For curved cuts, trace the outline using a template or freehand.
Step 2: Choose the Right Cutting Tool
Not sure which cutting tool is right? We’ve got you covered.
- Straight Cuts: Use a circular saw with a carbide-tipped blade for long, straight cuts.
- Curved or Intricate Cuts: A jigsaw or scoring knife is better suited for curved or detailed cuts.
- Quick, Straight Cuts: Electric or pneumatic shears can be faster and create less dust.
Step 3: Safety First
Put on your safety glasses, dust mask or respirator, hearing protection, and gloves. Place the Hardie Board on your workbench or sawhorses and clamp it down to prevent movement.
Step 4: Making the Cut
Now comes the exciting part! Cut your fiber cement boards the right way to go this way.
Using a Circular Saw
- Set Up the Saw: Adjust the depth of the blade to slightly deeper than the thickness of the Hardie Board.
- Position the Saw: Align the saw blade with the marked cutting line.
- Start the Cut: Turn on the saw and slowly guide it along the cutting line, applying steady pressure.
- Maintain Steady Speed: Keep a consistent speed to avoid chipping the edges.
Using a Jigsaw
- Select the Right Blade: Choose a fine-toothed blade designed for cutting fiber cement.
- Position the Jigsaw: Align the blade with the cutting line.
- Start the Cut: Turn on the jigsaw and follow the marked line carefully.
- Use Steady Movements: Apply steady pressure and move the jigsaw at a consistent pace.
Using a Scoring Knife
- Score the Line: Use the scoring knife to make several passes along the marked line, applying firm pressure.
- Snap the Board: Once the line is deeply scored, place your hands on either side of the score line and snap the board along the line.
Using Shears
- Position the Shears: Align the shears with the cutting line.
- Make the Cut: Squeeze the handles to cut through the board, following the marked line.
Step 5: Finishing the Cut
Use a sanding block or file to smooth rough edges and remove any splinters. Sweep up dust and debris from your work area, and dispose of off-cuts responsibly.
Tips for Perfect Cuts
Get perfect cuts every single time, the professional way!

- Mind the Speed: Cutting too quickly can cause chipping or damage to the board.
- Control Dust: Use a vacuum attachment on your saw or cut outdoors to minimize dust indoors.
- Check Blade Wear: Regularly check and replace dull blades to ensure clean cuts.
