FRAMING • Apply these lap siding products horizontally on walls and gables that meet racking requirements. • Follow product specific nailing pattern (see Fig. 4). • Framing must not exceed 16 in. on center (o.c.). • Although not recommended, where 24 in. o.c. vertical framing is used, nail to framing 24 in. o.c. with intermediate nailing 12 in. o.c. to sheathing with a 6d galvanized ring shank nail. This effectively creates a 12 in. o.c. nailing schedule.

FASTENING CLEARANCES • Use corrosion resistant boxhead nails with a minimum head diameter of 1/4 in. (10% variance allowed). • Siding must have a minimum 2 in. separation from concrete or be appropriately flashed. • Fastening must not exceed 16 in. o.c. (see Framing section for 24 in. o.c. stud spacing). • All lap products require that the butt joints be located on the studs and nailed at the joints (see Fig. 2). • Nails must penetrate wood framing 1-1/2 in.

• A minimum of 4 dry mils, which includes 1 mil factory primer, is required. This is best achieved with two coats of finished paint. • Drip edges and grooves must be well coated. INSTALLATION ERRORS THAT VOID THE WARRANTY • Do not apply siding to a rain soaked structure. • All surfaces and exposed cut edges must be painted in place. • Do not apply siding that is wet. Wet siding can shrink after application and shrinkage is not covered by the TruWood warranty.
