Nail Gun or Screw? The Best Method for Installing Fibre Cement Cladding
When it comes to installing fibre cement cladding, one of the decisions you’ll make is how to fasten the boards to the timber batten. The most common debate in this area is whether to use a nail gun or screws for installation. Both methods have their pros and cons, but one of them is better for long-term durability, precision, and superior holding power, let’s explore which.
What is Fibre Cement Cladding?
Before diving into the fastening debate, it's important to understand what makes fibre cement cladding unique. Made from a mixture of cement, sand, and cellulose fibers, fibre cement cladding is known for its durability, resistance to weathering, and aesthetic appeal. Whether you're renovating a home or constructing a new building, choosing the right fastening method is crucial for maintaining the integrity of this tough material.
Nail Gun vs Screws: Key Differences
Nail Gun: Speed vs Control
A nail gun is often chosen for its speed and ease of use, especially for larger projects. With a quick pull of the trigger, nails are driven into the cladding, securing it to the structure in seconds. For some contractors, this speed translates into lower labor costs and faster job completion.
However, there are some drawbacks:
Less Precision: Nail guns may cause slight misalignments or overdriving, especially if the pressure is not adjusted properly. This can lead to cracks in the fibre cement cladding and weaker boards, which can reduce its longevity.
Rattling Boards: When using a nail gun you don't get a firm, tight fixing against the timber batten. Overtime (Straight away in high wind areas) the boards will loosen and start to rattle or chatter in the wind.
Screws: The Better Choice for Durability
While screwing fibre cement cladding may take more time compared to using a nail gun, it offers several key benefits that make it the superior choice in most cases:
Better Holding Power: Screws penetrate the substrate more deeply than nails, providing a stronger, more secure hold. This is especially important for fibre cement cladding, which is denser and heavier than other materials like plastic or wood siding.
Reduced Risk of Damage: With screws, there's less chance of overdriving or cracking the material. The process of drilling a screw is more controlled, which reduces the stress on the cladding. This results in a cleaner, more professional finish.
Improved Durability: Screws are better equipped to handle natural building movement caused by weather changes or building settling. Over time, screws are less likely to loosen or fail compared to nails.
Easier Adjustments and Repairs: If a board needs to be repositioned or removed for repairs, screws make it much easier to do so without damaging the cladding. Nails, on the other hand, often require significant force to remove, increasing the risk of breaking the board or leaving unsightly holes.
Why Screwing is Better for Fibre Cement Cladding
Screws provide superior long-term performance when installing fibre cement cladding. Here’s why they should be your first choice:
Longevity: Screws maintain their grip and holding power longer than nails, meaning fewer maintenance issues down the road.
Better Withstanding of Environmental Factors: Fibre cement cladding is typically chosen for its resistance to extreme weather conditions, but the fasteners are equally important. Screws offer greater resistance to moisture and temperature changes, ensuring that your cladding remains tightly fastened, even in challenging environments.
Aesthetic Advantage: Screws are less likely to cause visible imperfections over time, ensuring the cladding maintains a neat, polished look.
Installation Tips for Screwing Fibre Cement Cladding
When opting for screws, it’s important to follow proper installation techniques to maximise the benefits:
Use corrosion-resistant screws: Fibre cement cladding is often exposed to moisture, so using stainless steel screws will help prevent rust and ensure longevity.
Self Drilling or Pre-drill: If you aren't using self drilling/tapping screws, to prevent cracking and make screw placement easier, pre-drill holes in the fibre cement boards before fastening.
Use a drill driver: These tools offer more control than an impact driver and help ensure the screws are driven to the correct depth without overdriving.
Space screws evenly: To distribute the load evenly, ensure you fix to all of the timber batterns, set at 600mm centers. (7 Fixings Per 3.6mtr Length)
Calculate Screw Quantity: Making sure you have enough fixings to complete your proiect is important. Use our handy fibre cement fixings calculator to help you work it out.
Conclusion: Nail Gun or Screw for Fibre Cement Cladding?
While a nail gun may seem like a quicker option, screwing fibre cement cladding is ultimately the better choice for durability, precision, and long-term performance. Screws provide stronger holding power, reduce the risk of damaging the cladding, and make future adjustments or repairs easier. By taking the time to screw the cladding properly, you ensure a more secure, lasting installation that will better withstand the elements and general wear and tear.
So, when you're installing fibre cement cladding, choose screws over a nail gun for the best results.
