The LP SmartSide 38 Series is a popular engineered wood siding and trim product designed for residential and light commercial construction. It offers a combination of durability, aesthetic appeal, and ease of installation, making it a preferred choice for contractors and DIY enthusiasts. This article provides a detailed, step-by-step guide on how to properly install the 38 Series, based on official manufacturer resources, technical guidelines, and best practices.
Overview of LP SmartSide 38 Series
LP SmartSide 38 Series is a line of lap siding, trim, and soffit panels made from composite wood fiber and synthetic resins. These materials are designed to resist warping, cracking, and splitting, offering a long-lasting alternative to traditional wood. The 38 Series is available in both primed and prefinished options, with smooth and cedar-textured finishes. It is ideal for use in a wide range of climates and is compatible with standard woodworking tools, reducing the need for specialized equipment.
One of the key features of the 38 Series is its ability to be installed over weather barriers and rain screens. However, it is not recommended for use in direct contact with masonry surfaces such as concrete, brick, stone, stucco, or mortar. This ensures long-term structural integrity and minimizes the risk of moisture-related issues.
Preparation for Installation
Before beginning installation, it is essential to gather the necessary materials and tools. The 38 Series requires standard woodworking tools such as saws, drills, and fasteners. No special tools are needed, as confirmed by LP SmartSide's official documentation.
Material Requirements
- LP SmartSide 38 Series Lap Siding
- Trim and fascia panels (if applicable)
- Nails or screws (as specified by the manufacturer)
- Primer and paint (for primed panels)
- Weather barrier or rain screen material (optional, as permitted by the manufacturer)
- Safety gear (gloves, goggles, etc.)
Stud Spacing Considerations
One of the key installation parameters for the 38 Series is stud spacing. According to LP SmartSide’s FAQ documentation, the 38 Series Lap Siding can be installed on studs spaced a maximum of 16 inches on center (o.c.). This is a critical distinction from the 76 Series, which can be installed on studs spaced up to 24 inches o.c. Therefore, it is important to ensure that the framing of the structure adheres to these specifications to maintain the structural integrity and performance of the siding.
Installation Process
The installation of LP SmartSide 38 Series involves several key steps, each of which is designed to ensure a clean, secure, and long-lasting finish. The following steps are based on official installation guides and instructional videos provided by LP SmartSide.
Step 1: Measure and Plan the Layout
Begin by measuring the area to be covered and planning the layout of the siding. It is recommended to start from the bottom and work upward, ensuring that each row is aligned properly. For lap siding, the standard overlap is 3/8 inch, which helps to create a uniform appearance and protect against water intrusion.
Step 2: Install the Starter Strip
A starter strip or a piece of siding cut to fit the bottom edge is used to create a reference line. This ensures that the first row of siding is installed correctly and provides a stable base for the rest of the installation.
Step 3: Install the Siding
With the starter strip in place, begin installing the siding panels vertically, ensuring a consistent 3/8-inch gap between each panel. Use nails or screws to secure the panels to the framing, following the manufacturer's fastener recommendations. Alternate fasteners such as staples may be used only if permitted by local building codes and designed by a licensed professional.
It is important to avoid direct contact with masonry surfaces. If the siding must be installed near such surfaces, a gap or spacer should be used to prevent moisture transfer and potential damage.
Step 4: Install Trim and Fascia
Trim and fascia pieces are used to finish the edges of the siding and provide a polished look. These components should be installed after the main siding has been completed. They can be cut to size using standard woodworking tools and secured with nails or screws. Special care should be taken when installing trim around windows, doors, and other penetrations to ensure a tight and weather-resistant fit.
Step 5: Painting and Finishing
If using primed panels, apply a high-quality primer and paint according to the manufacturer’s specifications. This helps to enhance the appearance of the siding and provides additional protection against the elements. Prefinished panels do not require additional painting, as they are already coated with a protective finish.
Special Considerations and Best Practices
Ripping Siding Panels
While it is generally not recommended to rip siding panels to create narrower pieces, there are instances where it may be necessary—such as when installing around soffits or around penetrations. When ripping siding, it is crucial to prime and paint any exposed wood fibers to prevent staining and degradation. This step is essential to maintaining the appearance and durability of the finished product.
Repairing Lap Siding Butt Joints
Over time, lap siding may develop issues at the butt joints where the panels meet. These issues can include gaps, warping, or staining. LP SmartSide provides specific guidance on how to repair these joints, including the use of sealants and proper fastening techniques. Any repairs should be conducted with care to maintain the integrity of the overall siding system.
ExpertFinish Technology
One notable feature available on certain 38 Series products is the ExpertFinish technology. This feature includes a lip on the profile of the panel that helps contractors align each piece with the exact 3/8-inch gap, eliminating the need for seam caulking, joint molds, or pan flashing. This technology is trademarked and available only on ExpertFinish products, making it a valuable tool for achieving a professional-looking finish.
Compatibility and Installation Limitations
Use Over Weather Barriers or Rain Screens
LP SmartSide 38 Series can be installed over weather barriers or rain screens. However, it is important to consult with technical support or review the manufacturer's guidelines for specific recommendations on compatibility. In some cases, additional moisture control measures may be required to ensure long-term performance.
Installation Over ICF Assemblies
It is important to note that LP does not recommend the use of panel siding in Insulated Concrete Form (ICF) assemblies. If used in such applications, LP will not provide a warranty for issues such as buckling or shrinkage. This restriction is due to the unique structural and thermal properties of ICF walls, which may not be compatible with the expansion and contraction characteristics of the siding material.
Frequently Asked Questions
Several frequently asked questions provide additional clarification on installation and product use:
- Can I use soffit panels as siding? Yes, there are two siding and soffit panels that can be used interchangeably. Refer to the LP SmartSide product catalog for more information.
- Are installation videos available? Yes, LP SmartSide offers an 8-part installation video series on their YouTube channel, which provides visual guidance on various aspects of installation.
- Can an installation expert visit the jobsite? LP SmartSide does not conduct on-site inspections or provide installation verification. Contractors are advised to seek third-party inspections or conduct a walk-through with a licensed professional to ensure compliance with installation guidelines.
Troubleshooting Common Issues
While LP SmartSide 38 Series is designed to be durable and low-maintenance, certain issues may arise during or after installation. These include:
- Warping or Buckling: This may occur due to improper fastening, incorrect stud spacing, or exposure to extreme moisture. Ensure that the siding is installed according to the manufacturer's specifications and that proper ventilation is maintained.
- Staining or Discoloration: Exposure to moisture or improper sealing can lead to staining. Always prime and paint exposed areas, and use high-quality sealants when necessary.
