Installing LP SmartSide lap siding is a project that can significantly enhance a home’s exterior appearance and provide lasting protection. The process, while manageable for experienced DIY enthusiasts, requires careful planning, adherence to specific techniques, and attention to detail. This article provides a detailed overview of the installation process, drawing exclusively from available documentation.
Preparation and Planning
Prior to commencing installation, thorough preparation is essential. This includes gathering the necessary materials and understanding the specific requirements for proper siding application. The initial step involves calculating the amount of siding needed, accounting for potential waste during cutting. In addition to the siding itself, required materials include starter strips, J-channels, corner posts, flashing, and appropriate fasteners.
Proper sheathing is crucial for siding stability; local building codes should be consulted to determine if wood structural panel wall sheathing is required. Installation of house wrap is also recommended, ensuring overlaps and secure taping of seams to create a water-resistant barrier. Flashing should be installed around windows, doors, and any areas where water diversion is necessary. A starter strip provides a solid base for the first course of siding.
Installation Procedures
The installation process begins with the application of the first course of siding. This requires precise measurement and cutting to ensure a proper fit, leaving a small gap at the bottom for drainage. Siding panels should be secured with fasteners, spaced according to manufacturer recommendations. Subsequent courses are installed by overlapping each piece, maintaining a minimum overlap of 1 inch (25 mm).
LP SmartSide 38 Series lap siding can be directly attached to framing members spaced a maximum of 16 inches (406 mm) on center, while LP SmartSide 76 Series siding allows for framing members spaced up to 24 inches (610 mm) on center. Fasteners used should be hot-dip galvanized with a smooth shank diameter of at least 0.113 inches; a 0.092-inch diameter nail may be substituted based on wind pressure, wind speed, and wind exposure category limitations as detailed in APA Product Report PR-N124 or ICC-ES Evaluation Report ESR-1301. Top (blind) nailing is the preferred method, with nails placed 3/8 inch (10 mm) from either end and a minimum of 3/4 inch (19 mm) from the top edge of the board. Fasteners will be exposed in areas below window sills, fascia boards, and horizontal trim.
Working Around Obstacles and Finishing Details
Cutting and installing siding around windows, doors, and other obstacles requires careful execution. A circular saw is recommended for precise cuts, ensuring a neat and tight fit. J-channels are used to create a finished appearance around these openings, secured with nails or screws.
Flashing is a critical component for preventing water damage. Kick-out flashing should be installed to direct water into the gutter, and step flashing, with a minimum 4-inch (102 mm) upper leg, should be integrated with the secondary water-resistant barrier using housewrap, flashing tape, or Z-flashing. It is important to avoid extending siding or trim into the kick-out flashing or gutter, maintaining a clearance for proper maintenance.
Trim pieces, such as corner posts and soffit trim, are used to complete the installation and enhance the overall aesthetics. Trim should be thick enough to ensure the lap siding does not extend beyond its face. Fascia and trim must be applied in a manner that prevents moisture intrusion or water buildup. LP SmartSide siding is not intended to be used as trim itself.
Caulking, Inspection, and Finishing
Once the siding is installed, all seams and gaps should be thoroughly caulked to prevent water infiltration. A careful inspection should be conducted to identify any gaps or unevenness, with necessary adjustments made to ensure a smooth and level appearance.
Finishing the siding involves painting or staining, following the manufacturer’s recommendations. A high-quality 100% acrylic exterior paint specifically formulated for wood or engineered wood substrates is recommended; oil paint is also acceptable. Stain should not be used, nor should vinyl-based paints (vinyl acetate or PVA). A satin finish is recommended for smooth finish lap siding. The finish coat should be applied as soon as possible, or within 180 days of application, adhering to the coating manufacturer’s application and maintenance instructions. All exposed cut edges must be sealed.
Common Mistakes to Avoid
Several common mistakes can compromise the integrity and appearance of an LP SmartSide siding installation. Improper sheathing installation can lead to instability, while uneven siding installation results in an aesthetically displeasing appearance. Insufficient fasteners can cause siding to become loose, and skipping the caulking step leaves the structure vulnerable to water damage.
Frequently Asked Questions
Specific questions regarding installation around windows and doors should be addressed by referring to the LP SmartSide installation manual for detailed instructions. Finishing edges can be accomplished using J-channel, corner posts, and soffit trim, attached with nails or screws.
Maintenance
LP SmartSide siding requires minimal maintenance. Periodic cleaning with mild soap and water is sufficient to remove dirt and debris. A pressure washer can be used on a low setting for more thorough cleaning.
Additional Tips for Success
Successful installation is enhanced by following several key tips. Diligently reading and adhering to the specific instructions provided with the LP SmartSide siding is paramount. Utilizing quality tools and materials significantly impacts the outcome. Accurate measurements and cuts, employing the “measure twice, cut once” principle, avoid costly mistakes. Working with a partner can improve efficiency and reduce stress. For those new to siding installation, starting with a smaller section of the home builds confidence.
