The LP SmartSide Trim & Fascia product line, encompassing 190, 440, 540, and 2000 Series Strand & Fiber Substrate with smooth or cedar texture finishes, requires specific installation procedures to maintain warranty coverage and ensure long-term performance. These instructions detail proper storage, preparation, and application techniques, with a strong emphasis on preventing moisture intrusion. The documentation highlights the importance of sealing exposed wood substrate and adhering to recommended fastening schedules. Improper installation can lead to reduced service life and void the LP SmartSide limited warranty.
On-Site Storage Procedures
Proper storage of LP SmartSide trim and fascia is crucial prior to installation. The material must be stored off the ground, supported adequately, and placed on a flat, well-drained surface. A waterproof covering is recommended, and when removed, all unit banding must be cut. Maintaining the cleanliness and dryness of the trim and fascia is also essential, with a pre-installation inspection advised. Additional support may be necessary to ensure adequate clearance from the ground.
General Installation Preparation
Louisiana-Pacific’s application instructions outline the minimum requirements for maintaining LP SmartSide limited warranty coverage. Installations that deviate from these instructions are susceptible to a reduced service life and may invalidate the warranty. A central tenet of proper installation is the prevention of moisture intrusion and water buildup. This applies to all exposed wood substrate, which must be sealed appropriately.
Sealing Requirements for Cut Edges and Joints
All exposed cuts of siding and trim require sealing to prevent moisture damage. Field spray applications of coatings on cut edges are not recommended. Sealing can be achieved through the application of a coating or sealant, adhering to the manufacturer’s specific requirements for that product. Butt joints are considered sealed from the weather when covered with joint molding, sealant, or a factory-finished end.
Fastening and Structural Considerations
LP SmartSide trim and fascia can be applied directly over existing materials like siding or fastened directly to structural members with a maximum spacing of 24 inches on center (610 mm). It is explicitly stated that these products are not intended for structural applications such as trellises, railings, fencing, decking, decking trim, or sills. Utilizing the product for such purposes will void the warranty and compromise its performance.
Integration with Water-Resistive Barriers
When integrating flashing with a water-resistive barrier (WRB), it is imperative to follow the WRB manufacturer’s installation instructions. Proper integration ensures a continuous moisture barrier and prevents water penetration behind the trim and fascia.
Substrate Moisture Content and Framing Quality
The documentation specifies that siding products should only be installed on walls with framing members that have been kiln-dried or air-seasoned to a moisture content of 19% or lower. Installation on walls with crooked framing materials is also prohibited, as this can compromise the integrity of the installation and lead to premature failure.
