Submit published third party design listings for fire resistance ratings and product thickness.
AWCI’s Construction Dimensions – October 2013
Materials must be applied in accordance with the project requirements for fire rating thickness, finish texture and color. All test results must be made available to all parties at the completion of each pre-designated area and approved awcci to the application of top-coat. Verify that substrate and workspace temperature and humidity conditions are in accordance with requirements of this section.
Final texture and finish of the factory-manufactured architectural fire protection surface must be completed prior to the application of the decorative top coat and in accordance with the approved mock-up samples. Steel substrate temperature shall be a minimum of 5 deg F 3 deg C above the dew point of the surrounding air for a period of 24 hours prior and during the application of the material.
Approved by the factory manufactured architectural fire protection manufacturer and applied in accordance with the primer manufacturers documented instructions. Fire Resistive Directory, Volume 1; Current edition.
Tcehnical factory-manufactured architectural fire protection material only to primed surfaces and in accordance with manufacturer’s installation instructions. In other words, the concrete can’t be too slick or too dry. Others claim that the instructions mean that the sample beam must be tested 12 inches from the end s of the member.
Technical Manual 12-B
What is the intended pattern? Apply decorative top coat in accordance with the manufacturer’s application instructions. Protect adjacent areas from over spray of fireproofing material.
Delete the next paragraph if not applicable. Final color, gloss and finish will be determined and approved by the Architect. Interchar is primarily a spray applied material, and performs without the requirement for any reinforcement. Verify that all clip hangers, piping, ducts, equipment or other items which would interfere with the installation of the factory-manufactured architectural fire protection system are not positioned or installed until installation is complete.
Areas will be designated by the Architect. Provide a mock-up for evaluation of surface preparation techniques and application workmanship. The magic drawing was a crude 3-dimensional image of an I-beam showing some of the nine points to be measured and then, 12 inches further along the beam, was another set of points to be tested. Before proceeding with the work, the installer will apply the primer, factory-manufactured architectural fire protection sections and decorative top coat to a representative substrate section of 10 square feet in size.
SECTION ARCHITECTURAL INTUMESCENT FIRE PROTECTION
Requests for substitutions must be made 30 days prior to submittal and contain the full name of each product, descriptive literature, testing data collected from industry consensus standard testing, data on past performance, manufacturer’s instruction for use and generic type.
Packaged materials must bear the appropriate labels, seals and designated certification mark for fire resistive ratings. Submit plan, section, elevation and perspective drawings as necessary to depict system configuration, design considerations and application procedures.
Include evidence that the fire testing aaci sponsored by the manufacturer and that the material tested was produced at the manufacturers facility under the supervision of third party certification personnel.
At project closeout, provide to Owner or Owners Representative an executed copy of the manufacturer’s standard limited warranty awcj manufacturing defect, outlining its terms, conditions, and exclusions from coverage. Factory manufactured architectural fire protection system will be a complete system from a single source consisting of primer, factory manufactured fire protection sections, section adhesive, edge sealant and decorative topcoat.
All manul listed in this section must be manufactured under the appropriate follow-up service with each container bearing the certified label mark. All surfaces to receive the factory-manufactured architectural 1-2b protection material must be clean, dry and free of oil, grease, loose mill scale, dirt, dust or other foreign substances which would impair bond of the architectural fire protection material to awcl substrate.
Clean substrate free of dust, dirt, grease or mannual foreign substances that would impair with the bond of the factory manufactured architectural fire protection adhesive material.
Maintain air temperature and relative humidity in areas where products will be applied for a time period before during and after application as recommended by manufacturer.
To ensure a concrete surface is clean and rough enough to receive a stucco finish, it may need to be sandblasted or mechanically abraded, a dash coat of the cement plaster mix can be ttechnical before the finish coat, or metal lath can be attached using poweractuated fasteners implying a two- or threecoat stucco system to follow. The use of a bonding agent may also improve the bond of portland cement plaster applied over relatively slick concrete, but the literature warns that one should ensure that it is an exterior grade bonding agent because a cheaper interior grade of bonding agent may not provide adequate bond.
Where necessary, cleaning or other corrections of the surfaces to receive the factory-manufactured architectural fire protection are the responsibility of the installer of the incompatible substrate. If the concrete lacks sufficient “tooth” for the plaster to bond to, it can eventually fail.
