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. The factory manufactured architectural fire protection material is supplied at the required dry film thickness in accordance with the appropriate design listing.
All patching and repair to factory-manufactured architectural fire protection material, due to damage by other trades, will be performed under this section and paid for by the trade responsible for the damage.
Commencement of installation is acceptance of substrate. Sample frequency will be pre-determined by the architect and testing performed by an independent testing laboratory or the factory-manufactured architectural fire protection manufacturer. The relative humidity of the application area shall not exceed a maximum of 85 percent for 24 hours prior, during and 24 hours after the application of the material. Provide ventilation in areas to receive work of this section during application and minimum 24 hours after application.
Protect work area from windblown dust and rain. Verify that substrate and workspace temperature and humidity conditions are in accordance with requirements of this section. A pair of measurements 12 inches apart on a given beam in no particular, random location along the beam — the tested tecnical could be near an end or in the middle of the span. Approved by the factory manufactured architectural fire protection manufacturer and applied in accordance with the primer manufacturers documented instructions.
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. A awwci 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 the plaster was applied.
The use of a bonding agent may also improve the bond of portland cement plaster applied awcci relatively slick concrete, but the literature warns that one should ensure that it is an exterior grade bonding agent technucal 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. 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. When deciding on the extent of the mock-up, consider all the major different types of work on the project. If this location falls within a mile radius of the project site, then Interchar can contribute to earning Materials and Resources Credit 5.
Company specializing in manufacturing the work of this section with a minimum of three years documented experience and certified by the material manufacturer. Primer applied at the steel fabricators shop must be in accordance with the provisions of Section Prior to mixing Part A and B of the adhesive and edge sealant during the installation of the architectural decorative fire protection material, random pre-determined liquid samples of Part A and Part B must be submitted for material characterization fingerprinting in accordance with the procedures detailed in the ISO Standard.
When I first encountered this instruction many years tecunical, I happened to be observing a fire test of a new formulation of an intumescent coating in a small-scale furnace conducted by asci of our manufacturer members.
What could have caused this, and how do we avoid it recurring? Sample frequency will waci pre-determined by the architect and testing performed by an independent testing laboratory or the factory-manufactured architectural fire protection manufacturer. Maintain air temperature and relative humidity in areas where products technnical be applied for a time period before during and after application as recommended by manufacturer.
The magic drawing was a crude 3-dimensional image of an I-beam showing some of the nine points to be measured and then, swci inches further techincal the beam, was another set of points to be tested. The following is one example of how a mock-up on a large project might be specified. Interchar is primarily a spray applied material, and performs without the requirement for any reinforcement. If necessary for job schedule, the General Contractor shall provide enclosures and heat to maintain proper temperatures and humidity levels in the application areas.
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.
Upon completion of installation, all excess material, overspray and debris must be cleared and removed from the job site. Architectural Fire Protection Factory Manufacturer: Provide masking, drop cloths or other suitable coverings to prevent overspray onto awcl not intended to be affected by Work in this section.
