PART 3 EXECUTION
 
3.1
EXAMINATION
A.
Do not begin installation until substrates have been properly prepared.
B.
If framing preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
3.2
PREPARATION
A.
Clean surfaces thoroughly prior to installation.
B.
Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
C.
Ensure that drainage plane in intact and all penetrations are sealed.
3.3
INSTALLATION
 
** NOTE TO SPECIFIER ** Wood framing provisions. Delete if not required.
 
A.
Wood Framing: Nominal 2 inch by 4 inch (51 m by 102 mm) wood framing selected for minimal shrinkage and complying with local building codes, including the use of water-resistive barriers or vapor barriers where required. Minimum 1-1/2 inches (38 mm) face and straight, true, of uniform dimensions and properly aligned.
1.
Install water-resistive barriers and claddings to dry surfaces.
2.
Repair any punctures or tears in the water-resistive barrier prior to the installation of the siding.
3.
Protect siding from other trades.
 
** NOTE TO SPECIFIER ** Metal framing provisions. Delete if not required.
 
B.
Metal Framing: Minimum 20 gauge (33 mm) 3-5/8 inch (92 mm) C-Stud 16 inches maximum metal framing complying with local building codes, including the use of water-resistive barriers and/or vapor barriers where required. Minimum 1-1/2 inches (38 mm) face and straight, true, of uniform dimensions and properly aligned.
1.
Install water-resistive barriers and claddings to dry surfaces.
2.
Repair any punctures or tears in the water-resistive barrier prior to the installation of the siding.
3.
Protect siding from other trades.
 
** NOTE TO SPECIFIER ** Local building code may permit the use of "water-repellent panel sheathing" instead of a "building paper type" water-resistive barrier. However, the manufacturer recommends the use of a "building paper type" water-resistive barrier in all siding applications. A vapor barrier may also be required.
 
C.
Furring: Install furring on a minimum 3/4 inch (19mm) rainscreen cavity, or in accordance with local building code for rainscreen requirements.
D.
Installation: Install materials in strict accordance with manufacturer's installation instructions.
 
** NOTE TO SPECIFIER ** Delete fastening method not required.
 
1.
Fastening Method: Exposed.
2.
Fastening Method: Countersunk and filled.
3.
Place fasteners no closer than 3/4 inch (9.5 mm) from panel edges and 2 inches (51 mm) from panel corners.
4.
Use fasteners as specified in the James Hardie Tech Data sheet and in the Hardie Reveal Panel Installation Instruction.
5.
Install panel using 1/2 inch (13 mm) spacers at horizontal joints. Leave bottom edge of panel above all horizontal trims exposed, no caulking shall be placed at this overlap of Horizontal Reveal Trim. Factory primed edge shall always be used.
 
** NOTE TO SPECIFIER ** Because of the volume of water that can pour down a sloped roof, one of the most critical flashing details occurs where a roof intersects a sidewall. The roof must be flashed with step flashing. Where the roof terminates, install a kickout to deflect water away from the siding. It is best to install a self-adhering membrane on the wall before the subfascia and trim boards are nailed in place, and then come back to install the kickout. To prevent water from dumping behind the siding and the end of the roof intersection, install a "kickout" of sufficient length and angle to direct the water running down the roof away from the siding. Delete if not required.
 
6.
Install a kickout flashing to deflect water away from the siding at the roof intersection.
7.
Install a self-adhering membrane on the wall before the subfascia and trim boards are nailed in place, and then install the kickout.
8.
Allow minimum vertical clearance between the bottom edge of siding and any other material in strict accordance with the manufacturer's installation instructions and as determined by James Hardie Zone.
9.
Maintain clearance between siding and adjacent finished grade.
10.
Specific framing and fastener requirements - refer to the applicable building code compliance reports.
3.4
FINISHING
 
** NOTE TO SPECIFIER ** James Hardie recommends a finishes with a flat sheen for Reveal Panel finishing. Delete if not required or not the work of this Section.
 
A.
Finish factory primed siding with a minimum of one coat of high quality 100 percent acrylic exterior flat grade paint with flat finish within 180 days of installation. Follow paint manufacturer's written product recommendation and written application instructions.
B.
Field cut edges shall be coated during the installation process using an exterior grade primer/sealer that is compatible with the type of paint to used on project.
3.5
PROTECTION
A.
Protect installed products until completion of project.
B.
Touch-up, repair or replace damaged products before Substantial Completion.
