• Avoid countersinking nails or rupturing the surface of the siding. If countersinking occurs, seal nail prior to painting (see Fig. 1). • Fasten from side to side or center side to avoid internal stress. • Nailing schedule for soffit application of siding products must not exceed 16 in. o.c. • For siding used as soffit material, the siding must be nailed 12 in. or 16 in. o.c. into the framing. GAPS AND CORNERS • For all shiplap edge panels, there should be a 1/16 in. gap between the underlap edge and the next panel. An alignment ridge helps with this placement. Do not force the edge of the panel over this ridge. • For Adobe panels, the shiplap edge will be visible unless a batten strip is used to cover it. • For square edge panels, there must be a 3/16 in. gap at the vertical joint (see Fig. 2). This gap must be sealed. It is recommended to cover the joint with a wood batten strip. TruWood Trim is recommended for batten material. • Leave 3/16 in. gap around all doors, window frames and corners. Seal all gaps (see Fig. 2 and 3). JOINTS • All side edge joints must be located over studs. • All horizontal joints must be located over framing. • At horizontal joints with stacked panels or other types of siding, overlap siding 1 in. or use Z flashing and fasten as shown (see Fig. 4). CLEARANCES • Siding must have a minimum 2 in. separation from concrete or be appropriately flashed. • Siding must be 6 in. from soil or landscaping material.
• Where the siding meets the roof, it must be spaced a minimum of 2 in. from the plane of the roof and be properly flashed. The cut edge must be primed and painted. • Vegetation must not be in direct contact with the siding. SEALING • Use the best quality flexible, paintable, mildew- resistant exterior grade sealant material that meets ASTM C920, Class 25 or higher. • Seal around all openings such as window and door frames and at butt joints. • Seal all overdriven nails (see Fig. 1) • Seal or flash all horizontal trim material in a manner that creates proper out-sloping. PAINTING • Touch up damaged areas with premium acrylic latex primer or premium alkyd oil-based primer. • Siding must be finish-painted within 90 days after installation. If siding is exposed for a longer period, reprime the siding. • Siding must be clean and dry when paint is applied. • Use only premium acrylic latex paint or premium alkyd oil-based paint containing an appropriate amount of mildewcide for local moisture conditions. • For best performance, use 100% acrylic latex paints or 100% acrylic latex solid body (opaque) stain. • Follow paint manufacturer’s recommendations for engineered wood siding. • 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. • All surfaces and exposed cut edges must be painted in place. 3
