Nailguns are versatile tools that simplify a wide range of construction and woodworking tasks. When it comes to siding, nailguns are indispensable, especially for the technique known as "blind nailing." In this article, we’ll explore the essential technical details about nailguns and the type of nails required for blind nailing siding.
Understanding Blind Nailing
Blind nailing is a technique used in siding installation to secure the siding material without visible nail heads. This not only enhances the aesthetic appeal of the project but also improves the structural integrity. It involves driving nails at an angle into the siding material, making them virtually invisible when the job is completed.
Selecting the Right Nailgun
Choosing the appropriate nailgun for blind nailing siding is crucial. Brad nailers and finish nailers are common choices, as they offer precision and control. Pneumatic nailguns are highly recommended for this task, ensuring consistent and reliable nail placement.
Nail Types for Blind Nailing Siding
The type of nails you select is paramount to the success of your siding project. To ensure a secure and long-lasting installation, consider these key factors:
-
Length: The length of the nails should be sufficient to penetrate through the siding material and into the underlying sheathing or studs. For typical siding applications, 2 to 2.5 inches nails are adequate.
-
Material: Opt for nails made from corrosion-resistant materials, such as stainless steel or galvanized steel. These materials are essential to prevent rusting, which can compromise the siding’s integrity.
-
Shank Type: Smooth shank nails are ideal for blind nailing as they offer superior holding power. Ring shank nails can also be a good choice due to their enhanced grip.
-
Head Type: For blind nailing, choose nails with small heads. These heads should be virtually invisible when driven below the surface of the siding. Look for nails with either a flat or slightly rounded head.
-
Angle: Most nails used for blind nailing siding are driven in at an angle of around 45 degrees. This ensures a secure grip without causing damage to the siding.
Installation Guidelines
Proper installation is key to the success of blind nailing siding. Here are the essential steps:
-
Prepare the Surface: Ensure the siding material and the underlying structure are in good condition. Remove any debris, protruding nails, or old siding.
-
Mark Stud Locations: Locate the studs or sheathing and mark them to guide nail placement.
-
Angle and Placement: Hold the nailgun at a 45-degree angle and drive the nail into the siding, aiming for the marked studs or sheathing. Make sure to leave the nail head slightly below the surface.
-
Spacing: Space nails according to manufacturer recommendations, typically every 16 to 24 inches horizontally and 6 to 8 inches vertically.
-
Check for Proper Depth: After nailing, run your hand over the siding to ensure the nails are slightly below the surface. If necessary, use a nail set to countersink any proud nails.
Conclusion
Blind nailing siding is a skillful technique that can greatly enhance the appearance and durability of your siding projects. To achieve the best results, it’s crucial to choose the right nailgun and nails, and to follow proper installation guidelines. By adhering to these technical details, you’ll ensure a secure, attractive, and long-lasting siding installation that meets both your aesthetic and structural needs.
