Installation Notes

• Acclimation: Allow the siding boards to acclimate to local environmental humidity on the jobsite for at least 24 to 48 hours prior to installation.
• Cutting & Sealing: Cut boards cleanly with standard woodworking framing saws. You must prime and paint all field-cut edges before fastening to protect the inner engineered wood core from water entry.
• Fastening Requirements: Fasten securely to structural wall studs or code-approved sheathing using hot-dipped galvanized or stainless steel siding nails. Avoid over-driving fasteners flush or deep into the board face.
• Clearance Gaps: Maintain a minimum 3/16-inch expansion gap at all butt joints, window frames, and corner trims, and seal joints cleanly with a high-quality exterior-grade sealant.

Frequently Asked Questions

• What are the primary performance advantages of engineered wood siding over traditional lumber?
  Unlike standard wood siding, LP SmartSide engineered wood siding is treated with advanced resins, waxes, and zinc borate. This engineering process makes the lap siding boards highly resistant to warping, splitting, knot-bleeding, insect damage, and fungal decay.
• Does this smooth siding board come painted, or do I need to finish it on-site?
  This product features a factory-applied smooth engineered wood lap siding primer that provides an optimal substrate for paint adhesion. It requires a final application of a high-quality, 100% acrylic latex exterior paint within 180 days of installation.
• What is the recommended installation exposure or reveal for an 8-inch siding board?
  An 8-inch wide lap siding board is traditionally installed with a 1-1/4 inch overlap. This standard lap alignment yields a clean, consistent 6-3/4 inch exposed reveal on your building's exterior walls.
