Check that no burrs or sharp arises remain which may prevent full coating thickness being attained. Alternative method includes abrasive blasting to AS 1627, Part 4, Class 1.
Remove oil and grease by the use of solvents. Abrasive blast to Class 2½ finish to AS 1627.4. Clean to a bright metal finish but avoid producing a polished surface. Select grit type and equipment such that the cleaned surface profile between peaks and valleys does not exceed one third of the dry film thickness. Check that no burrs or sharp arises remain which may prevent the full coating thickness being attained.
Remove grease, oil and other solvent-soluble contaminants by wiping and/or brushing with mineral turpentine or white spirit, according to AS 1627.1. Finally wipe with clean solvent. Allow to dry and proceed with the next operation immediately. Lightly abrade surface if required to provide adequate key for coating, taking care to only minimally reduce the galvanizing thickness.
Zinc primers must be free from zinc salts, remove if present. Remove grease, oil and other solvent-soluble contaminants by wiping with mineral turpentine or white spirit. Finally wipe with clean solvent. Allow to dry and proceed with the next operation immediately.
Each coat of paint and the completed paint system to have the following qualities and properties:
For some decorative or protective top coat products, if an architectural finish is intended include in this section a requirement to lightly abrade each coat and state that a high quality architectural finish is to be achieved. This will have a direct impact upon the application methodology and cost of the applied system. The required level of finish should be agreed between the Architect, Applicator and Owner by use of a control sample.
Apply specified Dulux primer to prepared steelwork in accordance with the primer manufacturer's Technical Data Sheet and to the required DFT for the specified Intumescent Coating System, refer to SELECTIONS for details. Test and record DFT as part of the project Q&A documentation.
If shop primed, allow for patch priming on site after erection
Clean areas of damaged priming and areas left clear for site jointing to a standard comparable with the shop cleaning specified. Wash off chemical deposits from welding fumes. Apply priming coats to same standard as shop primers, ensuring thorough coating of bolts, nuts and connection areas. Re-prime if the primer fails or more than the specified primer re-coat time has lapse before the final coating system is applied..
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.
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.
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.
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.
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.
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.
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.
