Step 3: Attach the board to the wall

Slide the plank firmly against the wall after bringing it up to it. Then, drive a few nails into the corner tabs’ opposing side. The board will be fastened to the wall by it.

Nail Gun For Hardie Trim Buying Guide:

Whenever you decide to buy a best nail gun for hardie trim, the following factors you should take into account:

Type of Nailer

The type of nail gun should be your first concern before you buy a nail gun for Hardie trim. For Hardie trim, various nail guns are available. Hardie boards operate well with coil siding nail guns, framing nailers, and roofing nail guns. Coil siding nailers are the finest option due to their excellent driving and nailing capability.

Magazine Capacity

It is crucial to take the magazine capacity into account while installing Hardie trim. The sizes of several nailers for Hardie siding range from 1 1/4 to 2 1/2 inches. With this typical length, you can complete most of your difficult Hardie trimming tasks.

Choose a magazine type that has sideways loading, as we’d advise because doing so can cut down on reloading time.

Depth Adjustment Option

Doing Hardie trim is a difficult operation. It’s vital to maintain the plank firmly lodged in the nail gun for a clean edge. A toolless depth adjustment can also complete the job for you. Furthermore, it gives you the most control and flexibility over the task.

Additionally, it enables you to achieve the correct nailing depth for the job. Therefore, search for a nail gun with a toolless depth adjustable option.

Dry Fire Lockout

This is a safety function of your nail gun that prevents accidental firing in times of insufficient nails in the magazine. To ensure your safety and comfort, look for a nail gun with a dry fire lockout feature.

Tool-free Jam Release

Look for a nail gun that comes with a tool-free jam-releasing system. Because nail jamming is the most frequent issue with the nailer it not only impairs the functionality but also kills more time and energy. This unique feature can clear off stuck and jammed nails in no time and makes the task easier.

Nail Gauge

Hardie trim usually requires a small nail gauge size because a larger nail gauge can create big holes in the trimming. A small nail gauge can ensure fine detailing and delicate finishing in the Hardie trim. Besides, it allows you to drive nails deeply into the materials and give you greater stability.

Contact or Sequential Mode

There are two firing modes available with nail guns. These are contact firing and sequential firing. Sequential firing involves shooting nails by every time pushing the trigger while contact firing involves the continuous firing of the nails with a single trigger push.

Good-quality nail guns come with a selectable trigger mode that allows you to switch between sequential firing and contact firing.


You should also consider the portability of nail guns. Lightweight nail guns are simple to handle and use. Because of their compact size and lack of bulk, they are less tiring to use for extended periods. Additionally, lightweight tools require less upkeep because they are simple to store and transport.

Ease of use

The best nailer for Hardie trim should have ease of use as one of its most important qualities. If you want to work safely and comfortably, you must opt for a lightweight nail gun. Because they are easy to operate.

Ensure that the ergonomics of the nail gun are sufficient to lessen fatigue and noise when you perform.

Bump Mode

Bump mode is an additional feature to look for in a nail gun. It can save you time and effort by enabling fast and consecutive firing. Besides, it also improves the efficiency of your project.


High-quality nail guns always come with an expensive price tag. But it doesn’t mean you should buy the most costly item all the time. We advise setting a spending limit, considering the things you seek in a nail gun, and then making a purchase that fits within your budget. Opt for a nailer belonging to a well-known brand because it always offers premium options.

Noise Level

Considering the noise level is important to ensure your safety during operation. Look for a nailer with an ergonomic handle since it reduces vibration and noise levels while you work. Some newest models come with an anti-vibration mechanism to maximize your comfort. You can go for it.


Hardie trim is a heavy-duty task. Therefore, you must need a durable nail gun that will offer high-end performance. Nail guns with high-quality construction materials will serve more years and will be worth the money.

We recommend buying aluminum or stainless steel nail guns since they can withstand any wear and tear. Avoid choosing plastic nailers at a cheap price because they are prone to breakage easily.


Well-known brands always provide high-quality tools with reasonable warranty times. So, conduct your study and choose the reputable brand we mentioned above. In addition, they offer 24/7 customer service for any product damage.
