Installing cedar tongue and groove (T&G) siding is a beautiful way to enhance the appearance and durability of your home’s exterior. However, the key to a successful project lies in selecting the correct nails. In this guide, we will provide you with accurate and concise information on the technical details and uses of nails for cedar T&G siding.

Nail Type: Stainless Steel or Hot-Dipped Galvanized

For cedar T&G siding, it’s essential to choose nails that are highly resistant to corrosion. The two primary options are stainless steel and hot-dipped galvanized nails.

1. Stainless Steel Nails:

• Corrosion Resistance: Stainless steel nails are exceptionally corrosion-resistant and are ideal for cedar siding, which is susceptible to decay and staining when in contact with moisture.

• Durability: These nails are known for their longevity and are less likely to develop rust spots, which could mar the appearance of your siding over time.

• Cost: Stainless steel nails are more expensive than galvanized nails, but they offer superior protection and longevity.

2. Hot-Dipped Galvanized Nails:

• Corrosion Resistance: Galvanized nails are coated with a layer of zinc, offering reasonable corrosion resistance. However, they are not as resilient as stainless steel nails.

• Affordability: Galvanized nails are more budget-friendly than stainless steel and are still suitable for cedar T&G siding.

• Use Cases: If your siding is in a relatively dry climate or less exposed to direct moisture, hot-dipped galvanized nails can be a cost-effective choice.

Nail Length and Gauge

The appropriate nail length and gauge depend on the thickness of your cedar T&G siding.

• Length: Nails for cedar T&G siding should be long enough to penetrate through the siding, sheathing, and into the wall studs. A common length range is 1-1/2 to 2-1/2 inches, but verify your specific project’s requirements.

• Gauge: The gauge refers to the thickness of the nail. For T&G siding, 15 or 16-gauge nails are suitable. These gauges provide the strength needed for secure fastening without causing splits in the wood.

Head Type

The head type of the nail can influence the finish and holding power. For cedar T&G siding, consider using:

• Brad Head: These nails have a small, flat head that is less likely to split the wood and provides a discreet finish.

• Trim Head: Trim head nails have a slightly larger head that offers better holding power. This can be useful if your siding is exposed to strong winds or other external forces.

Nail Installation Tips

To ensure a successful installation of cedar T&G siding, here are some important installation tips:

• Pre-Drill Holes: Pre-drilling small holes slightly larger than the nail diameter can help prevent splitting in the cedar.

• Spacing: Ensure proper nail spacing, which is typically between 6 and 8 inches apart along the length of each board.

• Nail Angle: Drive the nails in at a slight angle to avoid surface splitting and to ensure a secure hold.

• Use a Nailer: Consider using a pneumatic nailer for precise and efficient nail placement.

• Follow Manufacturer Guidelines: Always follow the manufacturer’s guidelines for the specific nails and siding products you’re using.

In conclusion, choosing the right nails for cedar tongue and groove siding is crucial to the success and longevity of your project. The main considerations are corrosion resistance, nail length and gauge, head type, and proper installation techniques. Whether you opt for stainless steel or hot-dipped galvanized nails, ensuring the correct selection and installation will contribute to the beauty and durability of your cedar siding.
