Hey there! As a supplier of pneumatic nail guns for siding, I often get asked about the recommended nail gauge for these tools. It's a crucial question because choosing the right nail gauge can make or break your siding project. So, let's dive into this topic and figure out what gauge is best for your pneumatic nail gun when it comes to siding.

First off, what exactly is nail gauge? Nail gauge is a measure of the nail's thickness. The lower the gauge number, the thicker the nail. For example, a 15 - gauge nail is thicker than an 18 - gauge nail. Different siding materials and applications require different nail gauges to ensure a secure and long - lasting installation.

Factors Affecting Nail Gauge Selection

Siding Material

The type of siding you're using is the most significant factor in determining the right nail gauge.

  • Vinyl Siding: Vinyl is a popular choice for siding because it's affordable, low - maintenance, and comes in a variety of colors. For vinyl siding, an 18 - gauge nail is usually recommended. These nails are thin enough to prevent the vinyl from cracking or splitting when driven in, but they're still strong enough to hold the siding in place. The relatively small size of the 18 - gauge nail also leaves a smaller hole in the vinyl, reducing the risk of water infiltration.
  • Wood Siding: Wood siding gives a classic and natural look to a home. Depending on the type of wood and the thickness of the siding, you can use either 15 - gauge or 16 - gauge nails. Hardwoods like oak or cedar may require the stronger 15 - gauge nails to penetrate and hold securely. Softer woods, on the other hand, can often be installed with 16 - gauge nails. These thicker nails provide excellent holding power, which is essential for wood siding that may expand and contract with changes in temperature and humidity.
  • Fiber Cement Siding: Fiber cement siding is durable, fire - resistant, and can mimic the look of wood. It's a bit more dense than vinyl or wood, so a 15 - gauge nail is typically the best choice. The 15 - gauge nail can penetrate the fiber cement without causing it to break or chip, and it provides the necessary strength to keep the siding firmly attached to the structure.

Siding Thickness

Thicker siding generally requires a thicker nail for proper installation. If the siding is thin, using a nail that's too thick can cause the siding to split or crack. Conversely, if the siding is thick and you use a nail that's too thin, it may not provide enough holding power, and the siding could come loose over time.

Wind and Weather Conditions

If you live in an area with high winds or extreme weather conditions, you'll want to use a thicker nail to ensure the siding stays in place. A 15 - gauge nail is a better option in these situations as it offers more resistance to the forces exerted by the wind and other environmental factors.

Common Nail Gauges for Siding and Their Applications

18 - Gauge Nails

  • Advantages: As mentioned earlier, 18 - gauge nails are great for vinyl siding. They're also relatively easy to drive, which can speed up the installation process. They're less likely to cause damage to delicate siding materials.
  • Disadvantages: They have less holding power compared to thicker nails. So, they may not be suitable for areas with high wind loads or for heavy - duty siding applications.

16 - Gauge Nails

  • Advantages: These nails offer a good balance between holding power and the ability to penetrate various siding materials. They're suitable for softer wood siding and can also be used in some light - to - medium - duty fiber cement siding applications.
  • Disadvantages: They're a bit more difficult to drive than 18 - gauge nails, and they may leave a slightly larger hole in the siding.

15 - Gauge Nails

  • Advantages: 15 - gauge nails are the strongest of the commonly used nail gauges for siding. They're ideal for hardwood siding, thick fiber cement siding, and areas with high wind loads. They provide excellent long - term holding power.
  • Disadvantages: They require more power to drive, which means you need a more powerful pneumatic nail gun. They also leave a larger hole in the siding, which may require more careful sealing to prevent water infiltration.
