The installation of James Hardie Shingle Siding requires careful adherence to specific procedures to ensure durability, warranty compliance, and a professional finish. Proper preparation, including surface assessment and material acquisition, is crucial. Installation involves aligning starter strips, maintaining consistent overlaps, and employing appropriate fastening techniques. Regular maintenance is also essential for prolonging the siding’s lifespan and preserving its aesthetic appeal. Professional installation is recommended to maximize efficiency and quality.
Preparing for Installation
Prior to commencing installation, thorough preparation is necessary. This includes removing any existing siding and ensuring the underlying wall surface is clean and dry. A water-resistive barrier must be installed in accordance with local building codes to prevent moisture intrusion. James Hardie manufactures HardieWrap® Weather Barrier, a compliant option. Irregularities in the framing or sheathing should be corrected before siding installation, as these can become visible in the finished application. The siding can be installed over braced wood or steel studs, with specific gauge requirements ranging from 20 to 16 gauge.
Measuring and marking are essential components of the preparation phase. Gathering the necessary materials, including starter strips, is also critical. The factory finish on James Hardie siding ensures consistent color, adhesion, and durability. Maintaining a level surface is vital for optimal results.
Laying the Starter Course and Initial Panel Installation
The installation process begins with laying the starter course. This involves using either 8-1/4″ or 9-1/4″ HardiePlank® lap siding to create a 1-1/4-inch starter strip, followed by an 8-1/4-inch starter course. Precise alignment of the bottom edges of the trim and siding is crucial for a uniform appearance. Maintaining this alignment throughout the installation of the starter strip and first course is key to achieving a visually appealing and durable finish.
Following the starter course, panels are installed from the bottom up. Each shake panel overlaps the one below it, creating a water-shedding surface. Fasteners are driven into the studs through pre-marked nail lines. Proper fastening techniques are essential for the longevity and performance of the shingle siding, allowing for material expansion and contraction.
Cutting and Handling Procedures
James Hardie siding requires specific cutting methods to minimize dust and prevent damage. When cutting outdoors, the cutting station should be positioned to direct airflow away from the user and others in the area. Acceptable cutting methods include:
- Best: A circular saw equipped with a HardieBlade® saw blade and an attached vacuum dust collection system.
- Better: A circular saw equipped with a dust collection feature (e.g., a Roan® saw) and a HardieBlade saw blade.
- Good: A circular saw equipped with a HardieBlade saw blade.
Indoors, cutting should be performed using shears (manual, pneumatic, or electric) or the score and snap method, but not with a power saw. Dry sweeping of dust should be avoided; instead, wet dust suppression or a vacuum should be used for collection. James Hardie recommends the “Best” cutting practices for maximum dust reduction. Always follow the equipment manufacturer’s instructions for proper operation.
Prior to installation, siding should be stored flat, kept dry, and covered. Installing wet or saturated siding may result in shrinkage at butt joints. Planks should be carried on edge, and edges and corners should be protected from breakage. James Hardie is not responsible for damage caused by improper storage and handling.
Corner and Edge Treatments
Correctly cutting and fitting shingle siding at inside corners ensures a seamless transition and prevents water infiltration. Careful management of corners and edges contributes to a professional appearance. Finishing bottom edges properly prevents water infiltration and protects the siding from moisture damage. Maintaining a minimum 1/4-inch space between siding and trim is crucial for effective moisture management.
Maintenance and Repair
Seasonal maintenance is crucial to protect James Hardie siding from weather-related issues. Proper maintenance prevents deterioration and extends the siding’s lifespan. Care methods should adapt to the specific challenges of each season. Implementing seasonal maintenance significantly improves the aesthetic appeal and structural integrity of the siding.
Minor damages can often be addressed without full replacement. For minor scratches on ColorPlus siding, touch-up kits are available to cover small blemishes. To clean oil or grease, use mild liquid dish soap mixed with water and a soft cloth, rinsing thoroughly. For mildew removal, use a mildew-specific cleaner and a soft sponge, following the instructions carefully.
Professional Installation and Contractor Selection
Professional assistance greatly enhances the efficiency and quality of James Hardie Shingle Siding installation. Professionals bring expertise and experience, ensuring the installation meets industry standards and is completed without unnecessary delays or mistakes.
When selecting a contractor, it is crucial to verify their experience with James Hardie products. Checking their portfolio of previous projects can provide insight into their workmanship quality. Researching local dealers for James Hardie products can connect homeowners with certified contractors who often offer warranties, providing protection for the siding investment and peace of mind.
Key Considerations and Requirements
Several general requirements must be observed during installation. HardieShingle panels can be installed over braced wood or steel studs, with specific spacing requirements. Information on installing James Hardie products over non-nailable substrates is available in JH Tech Bulletin 19 at www.jamehardie.com. Adjacent finished grade must slope away from the building in accordance with local building codes, typically a minimum of 6 inches in the first 10 feet. James Hardie products should not be installed in a manner that allows them to remain in contact with standing water. HardieShingle panels are intended for vertical wall applications only.
Conclusion
Installing James Hardie Shingle Siding is a detailed process requiring careful attention to preparation, installation techniques, and ongoing maintenance. From the initial surface preparation and starter course installation to proper cutting procedures and corner treatments, each step contributes to the siding’s durability and aesthetic appeal. Selecting a qualified contractor and adhering to manufacturer guidelines are essential for a successful and long-lasting result. Regular maintenance will further protect the investment and ensure the siding continues to enhance the home’s appearance for years to come.
