- Exception: LP® FlameBlock® Fire-Rated OSB Sheathing.
• Fastener size: Use a minimum 0.092 inch diameter ring shank
nail, hot-dipped galvanized (ASTM A153) or equivalent. Fasteners
shall be corrosion resistant and capable of preventing rust,
stain and deterioration under normal outdoor environmental
conditions for a period of no less than 50 years.
• Fastener placement: A minimum 3/4 inch (19 mm) down from
top edge of siding. Fasteners shall be placed 1 inch (25 mm)
from ends. (Diagram 3b & 4b)
• Fastener length: Long enough to fully penetrate wood
structural panel sheathing by at least 1/4 inch (6 mm). Ensure
that the ring shanks of the nail fully engage the wood structural
panel sheathing. (Diagram 3b)

General Application Equipment
Fastening Instructions - Sheathing Only
• Fasteners: Apply and correct overdriven
fasteners as shown in Diagram 3a.
• Sealant: Use an exterior-quality, non-
hardening, paintable sealant. Use a Class
25 or higher exterior sealant meeting the
ASTM C920 Standard for Speci cation for
Elastomeric Joint Sealants. Follow the sealant
manufacturer’s instructions for application.
• Paint: A premium quality exterior 100% acrylic
latex paint, specially formulated for use on
wood or engineered wood substrates is highly
recommended.
Semi-gloss or satin  nish oil
or alkyd paints are acceptable. For  at alkyd
paint, check with the coating manufacturer to
ensure it is suitable for engineered wood siding.
Diagram 3b
• For the cleanest cut and longer blade life, a  ne-tooth carbide tipped blade is recommended.
• Siding is manufactured with a special edge coating which reduces moisture intrusion. If siding is ripped you must take special
care to prime, paint and seal all exposed wood  ber as described in the Finishing Instructions on page 8.
• Climb cut the surface of the siding such that the rotation of the blade cuts downward on the primed or pre nished surface.
• Do not miter edges.
