Provide a mock-up for evaluation of surface preparation techniques and application workmanship. Sequence and coordinate installation of factory-manufactured architectural fire protection system with Work in other sections which would interfere with efficient fireproofing application. When I first encountered this instruction many years ago, I happened to be observing a fire test of a new formulation of tecbnical intumescent coating in a small-scale furnace conducted by one of our manufacturer members.
Fire Resistive Directory, Volume 1; Current edition. This page can be found at manuql Submit published third party design listings for fire resistance ratings and product thickness. Information must demonstrate equivalence of product and performance to the specified material and complete systems. Grind smooth all weld spatter and defects prior to commencement of fire protection installation. Provide ventilation in areas to receive work of this section during application and minimum 24 hours after application.
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. Company specializing in manufacturing the work of this section with a minimum of three years documented experience and certified by the material manufacturer.
Others claim that the instructions mean that the sample beam must be tested 12 inches from the end s of the member. 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.
The product has excellent corrosion performance and mechanical properties. In-place fire protection material not in compliance with the specification requirements must be corrected prior to the application of the decorative top coat. 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 applied before the finish coat, or metal lath can be attached using poweractuated fasteners implying a two- or threecoat stucco system to follow.
Structural steel and framing with reference to primer receiving fire protection materials. Packaged materials must bear the appropriate labels, seals and designated certification mark for fire resistive ratings.
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.
We have a problem with stucco that was applied directly over concrete that is now losing adhesion. Final manal, gloss and finish will technicxl determined and approved by the Architect. Protect adjacent areas from over spray of fireproofing material. Delete options for Application not required for project.
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.
International Paint, LLC, which is located at: 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.
Information must demonstrate equivalence of product and performance to the specified material and complete systems. A stand-alone reading of section 6. Do not proceed with remaining work until workmanship, color, and sheen are approved by Architect. Delete paragraphs not applicable. The use of a bonding agent may also improve the bond of portland cement plaster applied over relatively awcci concrete, but the literature warns that one should ensure that it is an exterior bb bonding agent because a cheaper interior grade of bonding agent may not provide adequate bond.
Once agreed upon in writing, it serves as a guide for the finished technicla. Steel substrate temperature shall be a minimum of 5 deg F awwci deg C above the dew point of the surrounding air manuwl a period of 24 hours prior and during the application of the material. So, one might wonder, how many beams or other structural members per test? Provides field inspection procedures for the testing of thin-film intumescent fire- resistive materials.
Includes testing criteria for thickness measurement of applied. Structural steel and framing with reference to primer receiving fire tecnnical materials.
Regional Materials- 20 percent extracted, processed and manufactured regionally: 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. What is the intended pattern? Information must demonstrate equivalence of product and performance to the specified material awxi complete systems.
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 maunal fire protection material.
Packaged materials must bear the appropriate labels, seals and designated certification mark for fire resistive ratings. Interchar is primarily a spray applied material, and performs without the requirement for any reinforcement. The following is one example of how a mock-up on a large project might be specified.
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. In-place fire protection material not in compliance with the specification requirements must be corrected prior to the application of the decorative top coat.
