Temperature and Humidity Requirements: 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. International Paint has operations in 54 countries worldwide and over 3, employees.

Remove fire protection materials from surfaces not required to be fireproofed.

AWCI’s Construction Dimensions – October 2013

International Paint, LLC, which is located at: 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 the plaster was applied.

Packaged materials must bear the appropriate labels, seals and designated certification 12–b for fire resistive ratings. Grind smooth all weld spatter techncal defects prior to commencement of fire protection installation. Sequence and coordinate installation of factory-manufactured architectural fire protection system with Work in other sections which technicaal interfere with efficient fireproofing application.

Company specializing in manufacturing products listed in this section with a minimum of ten years documented experience. Provide a mock-up for evaluation of surface preparation techniques and application workmanship. Others claim that the instructions mean that the sample beam must be tested 12 inches from the end s of the member. We have a problem with stucco that was applied directly over concrete that is now losing adhesion. There are several diagrams in B, but manal 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.

Interchar can provide fully fire proofed steelwork without the need to topcoat. Delete paragraphs not applicable. Equipment and installation procedures must conform to the factory-manufactured architectural fire protection manufacturer’s installation instructions. All batch number, product identification and quantities shall be recorded on appropriate QC documents.

The fire protection material inspection must be tedhnical prior to the application of the decorative top coat. Commencement of installation is acceptance of substrate.

Thickness determinations shall be made at nine locations around the beam, at each end of a in. Final color, gloss and finish will be determined and approved by the Architect. The factory manufactured architectural fire protection material is supplied at the required dry film thickness in accordance with the appropriate design listing.

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. Delete options for Application not required for project. Install factory-manufactured architectural fire protection material only to primed surfaces and in accordance with manufacturer’s installation instructions.

SECTION ARCHITECTURAL INTUMESCENT FIRE PROTECTION

All test results must be made available to all parties 1-b the completion of each pre-designated area and approved prior to the application of top-coat. 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.

Apply approved primer to properly cleaned substrate in accordance with manufacturer’s application instructions. Protect work area from windblown dust and rain. Temporary protection and heat shall be maintained at this minimum temperature for 24 hours before, during and 24 hours after material application. Information must demonstrate equivalence of product and performance to the specified material and complete systems.

Technical Manual 12-B

Structural steel and framing with reference to primer receiving fire protection materials. In other words, awco concrete can’t be too slick or too dry. 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. Fire Resistive Directory, Volume 1; Current edition. Some argue that when tevhnical a beam, the thickness must be tested in nine locations around the beam every 12 inches.

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. Regional Materials- 20 percent extracted, processed and manufactured regionally: The manhal must be witnessed by the Architect’s or Owner’s representative and is subject to their approval. Provide ventilation in areas to receive work of this section during application and minimum 24 hours after application.

Interchar is primarily a spray applied material, and performs without the requirement for any reinforcement. When I first encountered this instruction many years ago, I happened to be observing a fire test of a new formulation of an intumescent coating in a small-scale furnace conducted by one of our manufacturer members. 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.

After several failed attempts to explain this testing procedure to me I first took it to mean one must measure near each end of the beam, 12 inches inthe technical sales rep wound up drawing a diagram that finally made it clear.
