A stand-alone reading of section 6. Regional Materials- 20 percent extracted, processed and manufactured regionally: Interchar can techncial fully fire proofed steelwork without the need to topcoat. Delete options for Application not required for project.
Technical Manual B
There are several diagrams in B, but they are cross-sections of a beam, a column, a tube and a truss; the cross section of the beam includes arrows indicating the nine points around the beam where the film thickness of the TFIFRM is to be measured. All test results must be made available to all parties at the completion of each pre-designated area and approved prior to the application of top-coat.
Upon completion of installation, all excess material, overspray and debris must be cleared and removed from the job site. Others claim that the instructions mean that the sample beam must be tested 12 inches from the end s of the member. Patching must be performed by the qualified installer and applied in accordance with the manufacturer’s installation instructions.
Delete paragraphs not applicable. All surfaces to receive the factory-manufactured architectural fire 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 the substrate. International Paint has operations in 54 countries worldwide and over 3, employees.
When deciding on the extent of the mock-up, consider all the major different types of work on the project. 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.
Company specializing in installing the work of this section with a minimum of three years documented experience and certified by the material manufacturer. The wording of the instructions for testing the film thickness of Thin- Film Intumescent Fire-Resistive Materials on structural members in Technical Manual B can indeed be a bit confusing, especially when read without having first read the earlier passages in the manual.
Packaged materials must bear the appropriate labels, seals and designated certification mark for fire resistive ratings. Do not commence installation of the factory manufactured architectural fire protection system until the contractor, installer and inspector have examined the surfaces to receive the fire protection and determined the surfaces are acceptable to receive the fire protection material.
All batch number, product identification and quantities shall be recorded on appropriate QC documents. At project closeout, provide to Owner or Owners Representative an executed copy of the manufacturer’s standard limited warranty against manufacturing defect, outlining its terms, conditions, and exclusions from coverage.
SECTION ARCHITECTURAL INTUMESCENT FIRE PROTECTION
Remove fire protection materials from surfaces not required to be fireproofed. Apply decorative top coat in accordance with the manufacturer’s application instructions. To ensure a concrete surface is clean technifal 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 applied before the finish coat, or metal lath can be attached using poweractuated fasteners implying a mmanual or threecoat stucco system to follow.
Company specializing in manufacturing products listed in this section with a minimum of ten years documented experience. Delete the next paragraph if not applicable. What is the intended pattern?
AWCI’s Construction Dimensions – October 2013
Equipment and installation procedures must conform to the factory-manufactured architectural fire protection manufacturer’s installation instructions. 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 mmanual of the material.
Each layer of portland cement plaster that is qwci to the concrete should be damp-cured to prevent drying too quickly. What could have caused this, and how do we avoid it recurring? International Protective Coatings is the leading supplier of high performance Protective Coatings and forms part of Akzo Nobel, a market driven, technology based company specializing in Coatings, Chemicals and Pharmaceuticals.
The concrete could also have been considerably drier than the portland cement plaster when it was applied and absorbed too much of the moisture from the mix to ensure proper curing. If the concrete lacks sufficient “tooth” for the plaster to bond to, it can eventually fail.
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.
Deliver materials in manufacturer’s original, sealed, undamaged container with identification label intact. Final color, gloss and finish will be determined and approved by the Architect.
Technical Manual 12-B
A concrete surface could be too slick because it has been coated with some kind of sealer, or the forms left a tight surface that was not roughed up or otherwise pretreated before awdi plaster was applied. Structural steel and framing with reference to primer receiving fire protection materials. Include evidence that the fire testing was sponsored by the manufacturer and that the material tested was produced at the manufacturers facility under the supervision of third party certification personnel.
Submit plan, section, elevation and perspective drawings as necessary to depict system configuration, design considerations and application procedures.
Architectural Fire Protection Factory Manufacturer: The factory manufactured architectural fire protection material is supplied at the required dry film thickness in accordance with the appropriate design listing.
Verify that substrate and workspace temperature and humidity conditions are in accordance with requirements of this section. All products listed in this section must be manufactured under the appropriate follow-up service with each container bearing the certified label mark.
Store and dispose of hazardous materials, and materials contaminated by hazardous materials, in accordance with requirements of local authorities having jurisdiction. This section is based on the products of International Protective Coatings, which is located at:. Temporary protection and heat shall be maintained at this minimum temperature for 24 hours before, during and 24 hours after material application.
Jones is AWCI’s director of technical services. Materials must be applied in manuwl with the project requirements for fire rating thickness, finish texture and color. 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.
So, one might wonder, how many beams or other structural members per test? In-place fire protection material not in compliance with the specification requirements must be technicao prior to the application of the decorative top coat. Apply approved primer to properly cleaned substrate in accordance with manufacturer’s application instructions.
A copy of the transport document and manufacturers conformance certificate shall be attached to the material delivery QC form.
