How to Choose the Right Nail Gun for Trim

Nail Gun for Hardie Trim

After reading through the list, the choices are all overwhelmingly great. This can make choosing the best nail gun for Hardie trim somewhat difficult.

How durable is the nail gun?

When choosing the top quality nail gun for Hardie trim, durability is a big factor. Because a nail gun is an investment, you want to be sure you’re getting a durable, quality tool that will last you a lifetime (or at least several years.) Brands like BOSTITCH and Metabo HPT (formerly known as Hitachi) are renowned for their durability. That doesn’t mean that other nail guns don’t have great durability features as well.

A reputable brand is a safe choice but when choosing a lesser known brand, consider factors like power level and material. A durable steel housing is a great material.

Is there enough depth adjustment for my trim?

As you’ve probably figured by now, nail guns range drastically in size of nail and depth adjustment. This simply means how far in and what size nail can be driven in by the nailer. The nail gun for Hardie trim would need to be capable of 2” long nails. When applying Hardie siding and trim to your home, 2” nails are the most recommended size.

What additional features do you need for your nail gun?

While nail guns are relatively simple tools for a user of any experience level, added features can make the experience more comfortable for a novice or more technical for a pro. There are a few universal features we recommend for every nail gun.

The nailer should be lightweight. This ensures that you can work for long periods of time without getting exhausted or uncomfortable. A high capacity magazine is also a must have. This feature would allow the user to have more nails loaded into the gun at a time.

A 360-degree exhaust and debris deflector is a great feature to look for. This not only protects the user but will extend the life of the tool as well. The less debris getting trapped in the tool, the longer it will live.

Bump mode, anti-double fire, and safety lock are all important features as well. The nail gun for Hardie trim should have a bump mode. This allows the nail gun to continuously fire nails and will save loads of time on a project. The anti-double fire and safety lock will prevent accidents on the job site.

How to Install Hardie Trim

1. Trim the Hardie Trim prior to installation

Measure the length the pieces of trim will need to be and cut them accordingly. This can be done with a saw.

2. Attach Hardie Trim Flat Tabs 

The first step in setting up your Hardie trim to be installed is to attach the flat tabs. Using your nail gun of choice, attach the flat tab to the backside of the trim using four staples. This is best accomplished using a pneumatic staple gun.

3. Attach Hardie Trim to the Building

Once you have prepared the flat tabs to the back sides of the trim, you can begin attaching the trim to the side of the building. Position the trim to the side of the building and attach using 2, 6d siding nails fastened through the Hardie Trim flat tabs.

4. Remove Laminate Sheet

As soon as the Hardie trim boards are nailed in place, the laminate sheeting should be removed.

Here is a helpful video by James Hardie on installing Hardie Trim to your home.

Additionally, here is Hardie’s official guide for installing trim.


How much does Hardie Trim cost?

The cost of Hardie trim will depend on many factors. It will depend on the type of trim you choose and the amount you will need to cover your house. Siding can cost anywhere from $.70 to $5.25 per square foot. Generally, the overall cost will be anywhere from $4,700 to $13,300.

How do you attach Hardie Trim?

Hardie trim is relatively easy to install and can be attached with the right tools. The best tool to use to attach Hardie trim is a proper nail gun. The Hardie trim should be cut to size and then attached by nailing it to the side of the building with a nail gun.

Can Hardie board be sanded?

Hardie trim can be sanded, but because of the soft material it is not recommended. But, there is good news. Hardie trim is very easy to repaint or refinish and it does not need to be sanded or primed before.

How long does Hardie board last?

Hardie board can last many years because it is a fiber-cement material. This material can last at least 50 years. James Hardie warrants Hardie board for 50 years, but the material can last much longer than that. Painting and maintenance will prolong the life even more.


The clear winner of this roundup is the Metabo HPT nailer. This nail gun outshines the other in many areas. Unlike other nail guns on the list, it exceeds are expectations in power and durability. There is no shortage of power on this nail gun. It also has great safety features and a depth adjustment of up to 3 ½". This nailer is clearly the Best nail gun for trim.
