PART 3 - EXECUTION
3.1 Handling

1. Panels must be stored flat and kept dry before installation. A waterproof cover over panels and accessories should be used at all times prior to installation.
2. If panels are exposed to water or water vapor prior to installation, allow to completely dry before installing. Failure to do so may result in shrinkage at ship lap joints, and such action may void warranty.
3. When handling panels, carry panels on edges. Direct contact between the panel and the ground should be avoided at all times. It is necessary to keep panels clean during installation process.

3.2 Preparation

1. Job site conditions:
   1. Nichiha fiber cement panels can be installed over bracing wood, steel studs and sheathing including; plywood, OSB, plastic foam or fiberboard sheathing.
   2. Allowable stud spacing - max. 20" o.c.
   3. 18 GA, 3-5/8" min. width C-studs are required when installing to metal construction.
   4. Building wrap is required for all exterior applications. Use approved moisture resistive building wrap, per local building codes, over sheathing or studs. Do not use plastic wrap.
   5. Seal all penetrations including openings with building tape in accordance with local building codes. To minimize water penetration onto substrate, apply building tape around all wall penetrations, including openings.
   6. Approved corrosion resistant flashing shall be used in accordance with local building codes to prevent penetration of water into the wall cavity and to direct water out of the wall cavity at the base of the wall.

3.3 Installation

1. General: Install products in accordance with the latest installation guidelines of the manufacturer and all applicable building codes and other laws, rules, regulations and ordinances. Review all manufacturer installation, maintenance instructions and other applicable documents before installation.
   1. Install Nichiha Starter Strip with either nails or screws that penetrate the studs or sill plate a minimum of 1", not to exceed 20" o.c.. The starter pieces must be leveled, and applied a minimum of 6" above from soil finished grade or 2" above from hard finished surface, or per local building codes.
   2. Place the first panel in the starter and attach using Nichiha short clips at each stud. Verify first panel is leveled.
   3. Fit panels tightly together ensuring that panel edges are properly seated in the clips.
   4. Do not apply any caulk/sealant to the panel joints, unless panels are cut.
   5. When vertical joints fall between two studs, use Nichiha long clips to bridge the studs.
   6. Maintain minimum of 1" clearance between roofing and bottom edge of panel.

    2. Allow a minimum of 1/8" clearance between panel and trim or other products, and fill with high quality caulk/sealant in accordance with ASTM C-920.
13.  
14.  
15. Fasteners:
    1. Recommend 6d, stainless steel or galvanized or other corrosion resistant fasteners for wood construction, as recommended by fastener manufacturer.
    2. Provide #8, pan head stainless steel or galvanized screws or other corrosion resistant screws for steel construction, as recommended by fastener manufacturer.
    3. Nails must penetrate 1 inch or more into the wood studs, and screws must penetrate 3/8 inch or more into the steel studs.

3.4 Maintenance

1. Review complete Maintenance Manual for detailed instructions on care and maintenance of brick and stone fiber cement panels.
2. Cleaning:
   1. Rub walls with a soft brush using a diluted neutral detergent. Do not use hard tools such as a metal wire brush or other abrasive materials.
   2. If any portion of the panel surface is damaged, re-coat the damaged as soon as possible in accordance with manufacturer's written instructions.
   3. When cleaning sealant/caulk, follow same cleaning instructions as for panels.
