Introduction
Are you planning on doing sidings for your house and have picked fiber cement board siding for the job? Or maybe you’re looking for something else than the traditional wood board to work with, but don’t know what kind of differences there are?
Don’t look any further, but read from here. I’ve put some general knowledge together so that anyone considering cement fiber board sidings has a better chance of succeeding.
That being said, this is a general direction guide. Attaching different materials might need different means and you usually get manufacturer instructions about how you should do it.
Now, to read these instructions you don’t need to buy anything. You’ll get some idea on how to use cement boards to make sidings and maybe for other projects too.
Understanding Fiber Cement Board Siding
Fiber cement board siding is a popular choice among homeowners and builders for various reasons, including its impressive durability and aesthetic appeal. This type of siding has gained traction in recent years, and understanding its composition, advantages, and installation process can help you make an informed decision for your home renovation project.
Fiber cement siding is made from a mixture of cement, cellulose fibers, and sand, which gives it a unique combination of strength and flexibility. This composite material is engineered to withstand harsh weather conditions, making it an ideal choice for regions that experience extreme temperatures, heavy rain, or high winds.
With the increasing demand for sustainable building materials, fiber cement siding has emerged as a responsible option. Its production involves using recycled materials, and its longevity means less frequent replacement, reducing waste in landfills.
Cementitious board siding
Cementitious board siding is otherwise known by its most prevalent manufacturer, James Hardie. Hardie plank or Hardie board, whatever you choose to call it, is a cementitious fiber board made from pressed cellulose wood fibers and Portland mix. It’s been around for a hundred years so that might be a good measure for its qualities.
A high-pressure injection system provides cementitious fiber board with its durability and strength. Because of its cementitious nature, it is fireproof, water-resistant, insect resistant, and able to accept paints and caulks with ease. Its durability is a good quality in today’s world as recycling concrete provides already enough challenges.
Previously mentioned qualities make it a good building material for all kinds of conditions. It also lets us enjoy another kind of working with cement as we usually get to handle it in its soft form. It also has competitive pricing going for it so it’s good to consider it as an option.

How to install Hardie board siding by yourself
This guide is meant to give general directions. You might have other things that you need to consider while installing Hardie boards so read this through and take notes. I try to be as specific as I can imagining the project.
Before you start Hardie board installation
A good renovation always begins with tearing down the old materials. Some days I love it as it means you get to update your house, but other days it’s torture as there might be surprises waiting under the surface.
So before you begin any siding renovation, the old stuff has got to go. Removing everything down to bare wood is recommended, especially in older homes with tar paper as a waterproof underlayment.
More modern waterproofing barriers are mold and mildew-resistant. Foam insulation on top of the original wood, followed by a waterproof barrier such as Tyvek creates the perfect water and insulative barrier.
So if your house doesn’t have those it’s good to consider changing them while you’re at it. You are already tearing down exterior walls so why not take a step further.
Attach water table trim
Next, a piece of water table trim should be attached to the bottom of the area to be sided. By measuring down from the soffit, you can achieve a perfect look every time.
Using lasers or levels is worthless if the soffit is not leveled. By maintaining a consistent measurement around the perimeter of the home, your siding will look right, even though it may be a little out of level.
You can imagine this as two lines going in a little different directions. If you look at it from far away it might disturb you until you decide to do it again.
That being said, install window, door and soffit trim. Frieze trim should also be added over any roofing.
Nail the starter strip
A starter strip is then nailed just above the water table trim. This piece is also known as the kicker or faker.
It is simply there to keep the same profile of lapped siding. It is simply a ripped down piece of siding.
Nail the next whole piece of siding directly onto the kicker. Use galvanized roofing nails and a pneumatic roofing nailer for quick install times.
Keep the rows identical
The next row nailed on must maintain the same reveal or exposure. A simple storyboard or notched piece of wood can ensure each piece of siding has the same reveal.
Hardie board comes in varying thicknesses for different reveals. A minimum of 1 ¼” coverage is needed for the Hardie board. Work your way up the wall nailing each piece, staggering laps a minimum of two feet.
Cutting Hardie board can be done with a carbide blade in a skill saw or miter saw. Extreme amounts of dust, debris, and noise are generated when cutting, so protective gear is a must.
Another good tool is electric shears and a carbide jigsaw; perfect for cutting curves or other awkward cuts that may be impossible with a conventional saw.
Benefits of Fiber Cement Siding
Before you dive into the installation process, it’s essential to understand the numerous benefits of fiber cement siding. This knowledge will not only help you appreciate the material you are working with but also enhance your overall project experience.
One of the most compelling advantages of fiber cement siding is its durability. Unlike traditional wood siding, which can warp, crack, or become infested with pests, fiber cement siding is designed to withstand the elements. It is impervious to termites and resistant to rot, making it an excellent choice for homeowners looking for long-lasting solutions.
Additionally, fiber cement siding is fire-resistant. This quality provides peace of mind, especially in regions prone to wildfires. The non-combustible nature of the material means that it can help protect your home in the event of a fire, enhancing your safety and the safety of your family.
Moreover, fiber cement siding is aesthetically versatile. It can mimic the appearance of wood, stucco, or even masonry, allowing homeowners to choose a style that suits their taste and complements their home’s architecture. With a wide range of colors and textures available, you can achieve the desired look without sacrificing durability.
Another significant benefit is the low maintenance requirement. Unlike wood siding that needs to be painted or stained regularly, fiber cement siding retains its color and finish for many years. This characteristic not only saves you time and effort but also reduces long-term costs associated with maintenance and repairs.
Common Mistakes to Avoid During Installation
While installing fiber cement siding can be a rewarding project, there are several common pitfalls that DIYers should avoid. Being aware of these mistakes can save you time, money, and frustration in the long run.
One of the biggest mistakes is failing to properly prepare the surface before installation. Skipping the step of removing old siding or ensuring a smooth substrate can lead to issues with moisture retention and improper adhesion. Always take the time to prepare the area adequately before starting your project.
Another common error is not using the right fasteners. Since fiber cement siding is heavier than traditional siding materials, it requires specific fasteners to ensure a secure installation. Using the wrong type of nails or screws can lead to siding panels coming loose, resulting in costly repairs down the line.
Additionally, many homeowners underestimate the importance of proper sealing and caulking. Gaps between siding panels or around windows and doors can lead to water infiltration, which can cause mold and mildew growth. Make sure to use high-quality caulk and sealants to protect your home from moisture damage.
Finally, neglecting to follow the manufacturer’s installation instructions can be detrimental. Each brand may have specific guidelines that need to be adhered to for warranty purposes and optimal performance. Always read and follow the instructions provided by the manufacturer.
Additional Considerations for Fiber Cement Siding
When considering fiber cement siding for your home, it’s also important to think about the local climate and your home’s specific needs. For instance, in areas prone to heavy rainfall, making sure that your siding is installed with adequate drainage systems can further enhance its lifespan. Additionally, some homeowners may opt to apply a protective sealant or finish over their fiber cement siding to add extra protection against moisture and UV rays.
Another consideration is the color selection. Fiber cement siding can be painted, but it’s recommended to choose colors that are light or neutral to minimize heat absorption, especially in warmer climates. Darker colors can absorb more heat, potentially leading to issues with expansion and contraction over time.
Professional Help vs. DIY Installation
For those who may feel overwhelmed by the installation process, hiring a professional can be a wise choice. While DIY projects can be rewarding, fiber cement siding installation requires precision and skill. A professional installer will have experience, access to specialized tools, and knowledge of local building codes, ensuring that the job is done correctly and efficiently.
In contrast, if you have the time and are comfortable with home improvement projects, a DIY approach can be a fulfilling way to save money and take pride in your work. Just remember to take your time, follow the guidelines, and don’t hesitate to reach out for help if needed.
Inspiration and Design Ideas
To truly make your home stand out, consider various design ideas when planning your fiber cement siding project. You can mix and match different textures and colors to create a customized look that reflects your personal style. For example, combining smooth and textured boards can add depth to your home’s exterior, while using contrasting colors can highlight architectural features.
Additionally, think about integrating other materials alongside fiber cement siding. For instance, pairing it with natural stone or wood accents can create a striking aesthetic that enhances your home’s curb appeal. Consider consulting with an architect or designer to explore innovative design options that suit your vision.
Maintenance Tips for Fiber Cement Siding
Even though fiber cement siding is low maintenance, there are still some best practices to keep it looking its best. Regular inspections are essential; check for any signs of wear or damage, especially around seams and joints. Keeping the siding clean is also important; washing it with mild soap and water can help remove dirt, mold, and mildew that may accumulate over time.
Pay special attention to the trim and caulking, which may need periodic replacement to ensure a watertight seal. If you notice any peeling paint or stains, it’s essential to address these issues promptly to prevent further damage.
Conclusion
Installing cement fiber board siding should be done patiently like any other surface finishing job. You will be watching them for a long time after they are installed as the Hardie boards usually last few decades.
Take your time to see everything is going so that it is pleasing to the eye. It might not always be what a laser or level says, but sometimes you have to use your eyes with old buildings. Well, new buildings, as well as there, are a human factor in all of them.
Cement board siding panels are a nice way to build new surfaces as they come in standard size and are easy to put together. Playing with wood is sometimes such twisting and using leverage that it’s a nice change to work with something else now and then.
Also, the good thing is, these boards come with many different textures so you should be able to get one that you’re happy with during that time. They should also be a low maintenance option when compared to some competitors.
Not only sidings, if you have some other small projects, you could play around with these. Cement boards are used also as backer boards for bricks and ceramic tiles. Because these are resistant to water, they make a good base for many different projects.
You could also use cement board around fireplaces if you like to cover old brick walls around it or something else like that. It could give a new life for some rooms like that that you don’t know what to do with. It will save you time if you’re thinking of rendering those bricks.
In conclusion, choosing fiber cement board siding is not just a practical choice but also a smart investment for homeowners. Its unique combination of durability, aesthetic flexibility, and low maintenance makes it an attractive alternative to traditional materials. As you embark on your siding project, remember to consider the benefits, avoid common pitfalls, and adhere to proper installation techniques.
