CEP Panels, Inc. manufactures Stoneflex panels, which are glass fiber reinforced polyester resin architectural wall panels that are built up to provide a surface finish of natural stone aggregate, then oven cured. The panels are lightweight but strong, with high impact resistance. They are unaffected by climatic extremes, impervious to moisture, and will not delaminate or decay under any conditions. The panels are inorganic, rot proof, immune to attack by insects and vermin, and they will not nourish mold growth.

3. EXECUTION
   1. EXAMINATION
      1. Do not begin installation until substrates have been properly prepared.
      2. If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
   2. PREPARATION
      1. Measure areas of installation prior to fabrication, to minimize out of square or unbalanced border conditions.
      2. Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions. Proceed with panel installation only when substrate is completely dry.
   3. INSTALLATION
      1. Install in strict accordance with manufacturer's written instructions. Make adequate provisions for thermal and structural movement.
      2. Field Cutting: Perform field cuts with a dry cut diamond blade. Remove edge residue from cutting by using compressed air or a bristle brush.
      3. Space fasteners at a maximum of 8 inches on center around the perimeter and a maximum of 12 inches in the field of the panel. Space panels 1/4 in to 3/8 in apart. Support all panel edges on framing members.
      4. Seal joints between panels with polyurethane or silicone sealant in accordance with requirements of Section 07900.
   4. CLEANING AND PROTECTION
      1. Clean all panels of dirt, adhesive, and joint sealers, using detergents or solvents as appropriate and as recommended by the manufacturer.
      2. Remove and replace any damaged panels and those that cannot be adequately cleaned.
      3. Protect installed products until completion of project.
