Installing siding can make or break your home’s exterior durability. Though Hardie board is popular for its resilience, the key question is whether can cement board be used outside.
With this article, you’ll learn can you use cement board outside or not. We’ll also discuss the consequences of the Hardie board ground contact.
Read on to keep your investment secure.
What is Hardie board?
Hardie board is one of the best options for external siding. Despite having a wood or stone appearance, it easily resists rot, warping, and vermin. It requires expert installation and is hefty, but once it’s up, the installation becomes practically unbreakable. Homeowners who choose Hardie board for their cement board outside won’t regret it.
So, if you’re wondering whether can I use cement board outside – yes, and Hardie board is the standout choice. However, be cautious with cement board ground contact. Let’s clarify why.
Can Hardie board touch the ground?
Can cement board be used outside? Absolutely. But can you use cement board outside safely in any condition? That’s where it gets tricky.
Why Hardie board should not touch the ground
Hardie board isn’t designed to be in direct contact with the ground. When it touches soil, it’s exposed to moisture and risks quicker deterioration.
Hardie board installation issues and how to fix them
Placing Hardie board too close to the soil suggests trouble. As moisture wicks up, it may cause edema and deterioration. Trim your Hardie board back to provide the necessary clearance if it is too near the ground. Installing a moisture barrier or flashing will increase longevity and protection.
Recommended ground clearance for Hardie board
To prevent damage to the Hardie board, proper ground clearance is essential. Without it, moisture and other issues can compromise your exterior.
The recommended clearance distance from the ground
Keep Hardie board at least 6-8 inches above the ground. That’s the space that prevents soil contact, which is essential to avoid moisture damage. So, can Hardie board touch the ground? No, maintaining this distance is crucial.
How the 6-8 inches clearance improves longevity
Keeping the board elevated blocks moisture from seeping in. It prevents swelling, warping, and cracking. This space also minimizes the risk of mold growth and insect damage. To answer, can you use cement board outside—yes, but only when proper clearance is maintained. This ensures the board remains strong and durable for years.
The inadequate ground clearance dangers
Ensuring the proper ground clearance when installing cement board outdoors is non-negotiable. Without it, you could be setting yourself up for a host of problems. Here’s what can happen:
Moisture damage
Water is a powerful force. Prolonged exposure to soil moisture or puddles can gradually weaken the cement board, causing cracks and structural issues that compromise its effectiveness.
Mold and mildew growth
A damp environment is a breeding ground for problems. Mold and mildew can develop quickly on retained moisture, transforming your robust cement board into an ugly and harmful surface.
Insect damage
Ground-level installation can be an open invitation to pests. Wood-boring insects and other critters are drawn to moist areas, where they burrow in and cause hidden damage that erodes the board’s lifespan.
Premature wear
Weather and nature don’t wait. With little clearance from the ground, your cement board faces relentless exposure to rain, temperature shifts, and debris. It wears out faster, leading to cracks, warping, and an early replacement that hits your wallet.
So, the answer to can I use cement board outside is yes, but ensure your Hardie board is protected from these dangers.
The best way to install Hardie boards
As a James Hardie certified contractor, Plum ProExteriors know the best practices for long-term serving. Installing Hardie board properly can mean the difference between a project that lasts for decades and one that fails prematurely. Follow these best practices to protect your investment from harsh outdoor conditions and maximize the durability:
Create proper ground clearance
Don’t permit ground contact cement board. Always ensure your Hardie board has at least 6-8 inches of clearance from the soil. This simple step protects against water damage, insect invasions, and other moisture-related issues. A few inches of space can make all the difference.
Install a moisture barrier
Moisture creeps in where it’s least expected. Adding a high-quality moisture barrier between the frame and the ground contact cement board acts like armor, shielding it from water infiltration and preventing long-term damage. Stay protected with this hidden hero.
Avoid soil contact for any trim pieces
Trim pieces love to rot when they touch the ground. Keep them off the soil to avoid accelerated decay. Even the sturdiest Hardie board can weaken when trim soaks up water from below. Stay vigilant—keep trim dry and elevated.
Regular maintenance
There is no outdoor installation that can be completely forgotten. The key is routine maintenance and inspections. Scrub surfaces, look for cracks, and cover any exposed areas with a fresh seal. Your Hardie board remains resilient and prepared to withstand the weather year after year with the right maintenance.
