PRIOR TO INTUMESCENT COATING APPLICATION

Confirm surface preparation is in accordance with Fireshield Technical Data Sheet for specified intumescent coating.  Ensure surface is clean and dry, ready for intumescent coating.  Lightly abrade primer coat to provide a key.

 

If system includes primer, ensure primer condition is suitable and confirm primer is within re-coat time.  Ensure primer DFT summary documentation has been provided however the on-site applicator should carry out their own readings to confirm DFT of primer.  Proceeding with the application of intumescent coating implicitly accepts the condition and DFT of primer.

 

Ensure each steel section is adequately identified and required intumescent coating type and thickness confirmed.

3.34
INTUMESCENT COAT - GENERALLY

Apply selected Fireshield intumescent coat/s to coating manufacturer requirements and the required DFT specified for each fire rated structural steel member. If the on-site application of intermediate and/or finish coats is via brush/roller multiple coats will be required to achieve the nominated dry film thickness.

3.35
BOLTED / WELDED CONNECTIONS AND GALVANIZED BOLTS

For shop applied intumescent coatings, allow to mask off areas within 100mm of steel requiring to be site welded prior to shop application.  After site welding has occurred allow to clean and prepare area, apply primer and intumescent coating on-site in accordance with manufacturer's requirements.

 

For fire rated bolted connections allow to apply Intumescent coating at the same DFT of adjacent beam/column.

 

For galvanized bolts allow to degrease, abrade  and apply an approved primer coat prior to the intumescent coating of galvanized bolts.  Contact Dulux for FR Galvanized Bolt painting specification.

3.36
INTUMESCENT COAT - DRY FILM THICKNESS

Apply intumescent coating to the required DFT specified for each fire rated structural steel member.  Note the DFT's are item specific and are to be obtained from the Fire Loading Schedule issued by Dulux/Fireshield.  If DFT for fire rated sections are not detailed within, contact Dulux / Fireshield for details.  Refer to SELECTIONS for details.

3.37
INTUMESCENT COAT - DRY FILM THICKNESS DEFICIENCY REPAIR

Where DFT testing has confirmed that intumescent coating DFT is less than acceptable criteria, further application of coating is required.  Ensure that the application is within the re-coat time of intumescent coating.  Ensure surface is clean, dry and free from contamination, then apply intumescent coating to manufacturers requirements.

 

Where DFT testing has confirmed that intumescent coating DFT is more than manufacturer's acceptable criteria, contact manufacturer for corrective procedures.

3.38
APPLICATION TOP COAT - GENERALLY

For systems with decorative and/or protective (non-intumescent) top coat, lightly abrade intumescent coat to provide a key.  Apply top coat / coats by spray/brush or roller in accordance with the relevant product DuluxTechnical Data Sheet and manufacturer's requirements.  Refer to SELECTIONS for dry film thickness.

Not all systems require a topcoat depending on Atmospheric Corrosivity Category to AS/NZS 2312.1 / ISO 12944.2.  However a topcoat may be required for aesthetics / colour scheme.

 

There may also be a need to cover the situation where steelwork might be left exposed to the weather for a protracted period during construction.

3.39
APPLICATION TOP COAT - ARCHITECTURAL FINISH

For systems with decorative and/or protective (non-intumescent) top coat , if a high quality aesthetic finish is required prepare intumescent coat in accordance with TDS for architectural finish, this may require a thorough sand of the Intumescent coating prior to applying the top coat.  When sanding intumescent coatings always ensure adequate film build is maintained to provide the required DFT.

Ensure all members requiring an architectural finish are identified.

 

To ensure agreement on the visual standard, samples are recommended where the intumescent coatings are exposed to view with an architectural finish.

3.40
WEATHER PROTECTION OF INTUMESCENT COATED STEEL SECTIONS

Fireshield™ Architectural White and Fireshield™ SQ476 coating can be site or shop applied.

  • Ensure intumescent coated sections are not exposed to water, rain or moisture.
  • Ensure intumescent coated sections are protected against water on site.  If likely to remain exposed to weathering apply an approved top coat system to steelwork.

Refer to Application Instructions for further details. Water should never be allowed to pool on the surface or at the base of a column.

Completion
3.41
COMPLETION MATTERS

Refer to 1270 CONSTRUCTION for completion requirements and if required commissioning requirements.

Structural Steel Member Schedule
4.1
STRUCTURAL STEEL MEMBER SCHEDULE

Refer to ~ for structural steelwork schedule for Intumescent Coatings.

Add reference to where the required structural steel information is located (eg structural engineers documentation / fire engineers documentation), to enable the intumescent paint manufacturer to produce a Fire Loading Schedule for supply to the applicator with the required Dry Film Thicknesses.

 

For projects with only a few structural steel members requiring intumescent coating,  delete the above clause and add a schedule of structural steel items, as per the below table of Information required for each structural steel member.


The Intumescent coating manufacturer must be supplied with the following information to produce a Fire Loading Schedule for supply to the applicator with the required Dry Film Thicknesses:
