SMARTS <br />lEGENERAL NAILING (CONTINUED) <br />• There are no National Standards for wood composite substrate trim <br />• LP SmartSide trim and fascia can be applied directly over <br />materials such as siding, or nailed directly to structural <br />members up to 24" O.C. <br />• Do not let trim contact masonry. <br />• Minimum 6" clearance must be maintained between trim <br />and finish grade. <br />• Trim applied adjacent to porches, patios, walks, etc. must have a <br />clearance of at least 3/8" above any surface where water might collect. <br />The surface must be sloped or otherwise designed to provide proper <br />drainage so the siding is at no time directly exposed to standing water. <br />• LP SmartSide trim and fascia are not designed for (a) use as siding; <br />or (b) structural applications and should not be used as a structural <br />member in construction such as a trellis, railing, fencing. <br />• A non -corrosive drip -edge or drip -cap must be applied at bottom edge <br />of roofing where it meets the fascia. <br />• Trim and fascia must not be applied to green or crooked structural <br />framing members. Do not apply trim and/or <br />fascia over rain soaked or buckled sheathing materials. <br />u� <br />Moisture control and moisture vapor control are critical elements <br />of proper housing design. Check your local building codes for <br />application procedures for handling moisture and moisture <br />vapor in your area. <br />Follow all applicable building code specifications relating to <br />prevention of moisture intrusion into the wall assembly. LP <br />SmartSide trim and fascia is a wood product, and, as with all <br />wood products, must be kept free from constant sources of <br />moisture. Lack of proper ventilation; exposure to repetitive <br />sources of water such as sprinklers, condensation, inadequate <br />flashing; improper sealing; or failure to follow common building <br />practices that prevent moisture intrusion into the wall -system; <br />may cause damage, and will void the warranty. <br />• LP will assume no responsibility for water penetration. <br />• For the cleanest cut and longer blade life, a fine-tooth <br />carbide tipped blade is recommended. <br />• LP" SmartSide" trim and fascia are manufactured with a special <br />edge coating which reduces moisture -related issues. Ripping <br />of the trim and fascia is not recommended, as it will leave the <br />edges unprotected. If the trim or fascia materials are ripped, <br />take special care to prime, paint and seal all exposed wood fiber <br />as described in the finishing section. <br />Use a minimum 8d, corrosion resistant (according to <br />ASTM 641), box style nail, with a minimum 1/4" diameter head <br />Penetrate studs or studs and wood sheathing a combined 1". <br />• Leave 3/16" gap where trim butts into other materials and at <br />butt joints, miter joints and ends. Where edges of trim meet <br />siding material, windows, doors or other finished <br />openings, leave a minimum 3/16" gap to allow for proper <br />sealing. Provide increases spacing along the trim if specified by <br />the siding installation instructions. <br />• Leave 1" clearance between trim and roofing materials <br />at roof rake. <br />• For edge -nailing, all nail holes must be pre -drilled. Do not attempt <br />to edge -nail without pre -drilling. <br />• When applied as rake, corner or band board, nails must <br />be spaced no further than 12" apart on alternating edges. Nails <br />must be at least 3/e" from the edge. <br />CONDITION CORRECTION <br />Snug ® OK ta <br />Flush (Cl <br />OK <br />Visible fiber ® Paint <br />Countersunk'/16"-1/e" _ t1a® Seal with caulking—® <br />Countersunk more Seal with caulk and — <br />than 1/e" lley re -nail <br />WINoows, DOORS & OPENINGS <br />• All openings must be sealed and flashed in a manner that <br />prevents moisture intrusion or water buildup.
