Lp Smart Siding Shakes Installation Guide
Installing LP Smart Siding shakes offers a durable, natural-looking exterior with enhanced resistance to common weathering. This guide covers planning, material choices, and step-by-step installation best practices to help homeowners and contractors achieve a professional, long-lasting result. Emphasis is placed on proper fasteners, flashing, expansion gaps, and maintenance to maximize the life of LP Smart Siding shakes in American climates.
Preparation And Planning
Begin with a thorough site assessment and material check. Confirm that the wall surface is clean, dry, and free of rot or damage. If replacing existing siding, remove it and inspect the underlying sheathing for decay, ensuring it is solid and square. Gather all components, including LP Smart Siding shakes, backer board or rain-screen material, starter strips, fasteners, flashing, and caulk. Plan for a continuous weather barrier and ensure proper ventilation behind the siding to reduce moisture buildup.
Understand climate considerations in the United States. In regions with heavy rainfall or humidity, prioritize a full weather-resistive barrier, proper flashing at windows and doors, and a robust ventilation gap. For cold climates, account for freeze-thaw cycles and ensure adequate drainage away from the structure. Accurately measure wall areas to estimate the number of shakes, furring strips, and starter rows required for a uniform appearance.
Materials And Tools
Use LP Smart Siding shakes designed for exterior applications and compatible with a rain-screen system if recommended by the manufacturer. Additional items include corrosion-resistant nails, starter strips, edge trims, corner boards, flashing membranes, exterior-grade caulk, and a suitable sealant for trim details. A quality utility knife, chalk line, speed square, screw gun or drill, hammer, pry bar, and a specialty siding nailer can speed installation while protecting the material.
Choose fasteners suitable for engineered wood products and the local climate. Stainless steel or galv aluminum nails with a proper length for substrate thickness prevent nail-head corrosion and ensure strong hold. Avoid overdriving nails to prevent dimpling or splitting the shake profiles. Also consider a moisture barrier compatible with LP Smart Siding to maintain the product warranty and performance across temperature shifts.
Installation Steps
Install a continuous weather barrier and, if specified, a vented rainscreen behind the shakes. Begin with a straight, level starter strip along the bottom edge, securing it to create a uniform base line. Install first course of shakes with the tapered reveal oriented outward to ensure consistent shadow lines. Keep fasteners 3/8 inch to 1/2 inch from the edge and through the stud or sheathing as recommended by the manufacturer.
Stagger joints between courses to avoid reveal alignment and to improve water shedding. Use a top-notchible nail pattern on each each piece, and ensure nail heads do not penetrate through the front face of the shake profile. Cut shakes with a sharp utility knife or a fine-tooth saw for clean edges, and create proper venting around electrical boxes and other penetrations to prevent moisture entrapment.
Work from left to right and end with full-sized shakes where possible to minimize visible seams. When tying into existing structures, use compatible trim pieces and flashing to seal joints. Maintain a consistent gap for expansion and contraction, particularly in hot or cold environments. If using corner boards, align and secure them tightly to create a crisp, museum-like edge to the installation.
Flashing And Sealing
Flashing is essential at doors, windows, and transitions to prevent moisture intrusion. Install integrated flashing strips above windows and behind corner boards where shakes intersect. Seal all joints with high-quality exterior caulk, focusing on gaps at trim and corners. Ensure the bottom edge of the siding sheds water away from the wall by maintaining a slight slope to the exterior.
For openings and penetrations, use backer rod and silicone or an elastomeric sealant designed for exterior use. Confirm that flashing materials are compatible with LP Smart Siding’s installation guidelines and local building codes. A properly flashed system reduces rot risk and preserves aesthetic integrity over time.
Finish And Maintenance
Inspect the installed shakes for alignment, nail gaps, and bare areas after the first installation cycle. Touch up any exposed edges or fastener heads with the recommended exterior finish to protect against moisture and UV exposure. Regularly clean the siding to prevent dirt buildup, and inspect for signs of swelling, cracking, or delamination after severe weather. Address any issues promptly to prevent further damage.
Maintain a routine inspection schedule, especially after extreme weather events. Clear debris from vents and gaps that could hinder airflow or trap moisture. Recaulk or reseal joints and trim as necessary, following the manufacturer’s color and finish recommendations to preserve curb appeal and warranty coverage.
Common Issues And Troubleshooting
Potential issues include improper nailing that can cause warping, misalignment due to uneven walls, and moisture infiltration at seams. If shakes appear loose, verify that fastener type and spacing meet guidelines, and inspect the underlying substrate for movement. Warping or cupping may indicate moisture accumulation; recheck barrier installation and ensure adequate drainage. Inaccurate cuts can create gaps; re-trim sections to restore a tight fit.
Professional inspection is advised if there are persistent signs of structural movement or water intrusion. Following manufacturer guidelines for expansion gaps and recommended fastener patterns minimizes common problems and helps sustain the product’s performance over time.
