Trim work can greatly enhance the aesthetic appeal of any building, whether it's a cozy home or a grand commercial structure. The right trim adds decorative flair and provides crucial protection and coverage for joints and edges. However, selecting the appropriate nails for trim work can be daunting, especially considering the various applications and materials involved.

This blog post aims to guide you through choosing the best nails for different types of trim work, focusing on exterior and Hardie trim applications.

Why Nail Selection Matters

Choosing the right nails is essential for your trim work's durability and appearance. Using the wrong type of nail can lead to issues like rust, splitting, or even structural failure. T

What Nails Use For Exterior Trim

Weather Resistance is Key

When it comes to exterior trim, weather resistance is a top priority. Your trim will be exposed to the elements, including rain, snow, and fluctuating temperatures. Therefore, it is crucial to choose nails that can withstand these conditions without rusting or losing their structural integrity.

Hot-Dip Galvanized Nails

One of the best options for exterior trim is hot-dip galvanized nails. These nails are coated with a heavy zinc layer, offering excellent protection against rust and corrosion. They are particularly effective in humid or coastal environments where moisture is constantly concerned.

Size and Length

For exterior trim, a minimum nail length of 3 inches is recommended. This length ensures the nail penetrates deep enough into the underlying material to provide a secure hold. Additionally, a thicker gauge nail is advisable for added strength.

What Nails to Use For Hardie Trim

Understanding Hardie Trim

Hardie trim, made from fiber cement, is renowned for its durability and low maintenance. However, its unique composition requires specific types of fasteners to ensure long-lasting results. Using the wrong type of nail can lead to premature wear and tear, compromising the integrity of the trim.

Plastic Strip Nails

For Hardie trim, plastic strip nails are highly recommended. These nails are designed to work seamlessly with the material, providing a strong and durable hold. Depending on your nail gun type, 20-22 plastic strip nails are the most common choice. Benefits of Plastic Strip Nails

Hot Dip Galvanized and Stainless Steel Plastic strip nails offer several advantages for Hardie trim applications. They resist corrosion, ensuring your trim remains secure and aesthetically pleasing for years. Additionally, they provide a smoother finish, reducing the risk of chipping or cracking during installation.

Factors to Consider

Material Compatibility

Always ensure that the nails you choose are compatible with the material of your trim. Different materials have different properties, and using the wrong type of nail can lead to issues like splitting or inadequate holding power.

Environmental Conditions

Consider the environmental conditions where the trim will be installed. For example, coastal areas with high humidity levels require nails that offer superior corrosion resistance, such as hot-dip galvanized nails.

Ease of Installation

Some nails are easier to install than others, particularly when using a nail gun. Plastic strip nails, for example, are designed to work seamlessly with specific types of nail guns, making the installation process faster and more efficient.

Get Your Project Started

Selecting the right nails for trim work is essential for achieving a professional and long-lasting finish. Whether you're working on exterior trim or Hardie trim, it's important to consider factors like weather resistance, material compatibility, and ease of installation.

For outside trim, use hot-dip galvanized nails. For Hardie trim, use plastic strip nails. This will ensure that your trim work remains strong, long-lasting, and looks good.
