3.7
SEQUENCE OF OPERATIONS

Complete surface preparation before commencing painting. Apply paint in the specified sequence using the specified paint. Allow full drying time between coats to the manufacturer's stated requirements. Do not expose primers, undercoats and intermediate coats beyond a few days before applying the next coat.

3.8
DRYING & OVER-COATING TIME

Ensure that surfaces being painted are clean, dry and that ambient conditions are such that condensation does not occur before the paint reaches surface-dry condition.

Before handling or applying the next coat of paint, give each coat the required drying time required by the manufacturer.

Where high film builds of intumescent are required, apply in thinner multiple coats.  Ensure that surfaces being painted are clean, dry and that ambient conditions are such that condensation does not occur before the paint reaches surface-dry condition.

Multiple thinner coats should be applied in the cooler months of the year, to ensure that not only specified dry film thickness is achieved, but also the complete evacuation of solvents from the film.  This will give each coat a chance to gain sufficient hardness so as not to suffer undue handling damage in-shop or during transport to site.

3.9
INSTALLATION OF SUNDRY ATTACHMENTS

Ensure clips, hangars, supports, sleeves, precast concrete panel connections and other attachments specified under other work sections are placed and fixed before the application of the coating.

3.10

Refer to the general section 1270 CONSTRUCTION for general requirements.

Amend this clause to describe specific standards and tolerances to be achieved in carrying out this part of the work. Although such tolerances are typically included in standards (NZS, AS/NZS etc) in certain circumstances it is worth restating these in this clause.

Application - surface preparation
3.12
UNPAINTED SURFACES

Do not paint:

  • Faying face of high strength friction grip (HSFG) bolted joints
  • Areas for site welding keeping 75mm clear all round
3.13
SURFACE PREPARATION

Remove all slag.
Ensure that all cut edges are ground to a smooth 2mm radius.

The following applies:

For welds exposed to view:

Remove weld splatter and grind to a neat, clean finish

For intumescent fireproofing coating:

Remove rust and mill scale by abrasive blasting to SSPC SP10 (AS1627.4 Class 2½)

Pre-clean steelwork to SSPC SP1 (AS 1627.1), then carry out abrasive blasting or power tool preparation after completion of the fabrication.  Apply required coating to the coating manufacturer's requirements.  Apply primer coat within 4 hours of preparation. Work off site wherever possible. Surfaces that are in contact or near contact are to receive specified coating before assembly.

Note: some fire protection requires less aggresive preparation, check with manufacturer.

3.14
CONDITIONS FOR PREPARING STEELWORK BEING PAINTING

Prepare steelwork in conditions approved for the application of coatings.  Carry out off site preparation and coating applications under cover, in a controlled environment and with adequate lighting.

Delete these clauses when this preparatory work is to be carried out on site by the painter.  Amend also when decorative or protective finishes are covered elsewhere, such as in PAINTING sections.

3.15
POWER TOOL DISC CLEANING

Remove oil and grease by the use of solvents.  Scrape and power disc prepare to Class St3 standard in accordance with AS 1627.2 (SSPC SP3) and avoid producing a polished surface. Check that no burrs or sharp arrises remain which may prevent full coating thickness to be attained.

Delete this clause if the following abrasive blasting clause is used.

Used for non aesthetic/concealed interior steelwork.

3.16
ABRASIVE BLASTING

Remove oil and grease by the use of solvents.  Abrasive blast clean to Class 2½ finish to AS 1627.4 (SSPC SP10) and achieve a blast profile between 38 - 75 microns. Clean to bright metal but avoid producing a polished surface. Select a suitable blast media 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 arrises remain which may prevent the full coating thickness being attained.

Solvent cleaning will not remove chlorides.

Most commonly used for exposed interior steelwork and exterior steelwork.

3.17
PREPARING GALVANIZED SURFACES FOR DUPLEX COATING

Round all cut edges to a smooth 2mm radius prior to galvanizing.

Do not dichromate quench as part of galvanizing process prior to duplex coating. Remove grease, oil and other solvent-soluble contaminants by solvent wiping with D30 Degreaser/Dewaxer. Allow to dry and proceed with the next operation immediately. Abrade galvanized surfaces via controlled sweep blasting or abrading to a matt finish.

Contact the manufacturer if unsure of this process.

The recommended approach to preparing galvanized steel is by controlled sweep blasting in a shop environment.

3.18
PREPARING ZINC PRIMED SURFACES

Zinc primers must be free from zinc salts, remove if present. Remove grease, oil and other solvent-soluble contaminants by solvent wiping with Altex D30 Degreaser/Dewaxer. Allow to dry and proceed with the next operation immediately.

All zinc primed surfaces are to be lightly abraded to achieve a surface key. Areas of smooth or glossy surfaces are to be abraded to a matte finish.

3.19
PREPARING FOR SPRAYED CEMENTITIOUS FIRE PROOFING

Ensure all substrates are clean and free of loose scale, dirt, oil, grease, condensation, or any other substances that would impair adhesion. Degrease steel where necessary and wire brush to remove loose rust.

Application - general
3.20
APPLICATION - SPRAYED CEMENTITIOUS FIRE PROOFING

Ensure building area is watertight before commencing installation. Mix and apply Altex Cementitious fireproofing to prepared substrate in accordance with selected Resene or Altex product Technical Data Sheet and manufacturer's requirements to specified DFT to achieve required FRR.

3.21
EACH COAT

Each coat of paint and completed paint system to have the following qualities and properties:

  • Uniform finish, colour, texture, sheen and hiding power
  • Correct number of coats applied and DFT achieved
  • Free of defects such as pin holing, alligatoring, blistering, staining, overspray, peeling, runs, sags and wrinkling.

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.

3.22
PRIMING -GENERALLY

Apply specified Altex or Resene 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.

 

The maximum average thickness of primer (measured according to ASFP TGD 11 guidelines) for an item to be coated with intumescent should not exceed a dry film thickness (DFT) of 150 microns. Any single spot reading shall not exceed 250 microns and any 3-point average reading should not exceed 200 microns DFT.

 

If shop primed, allow for patch priming on site after erection

Generally use high build primers to give a single coat thickness of between 50 microns and 75 microns.  Use primers that suit the standard of preparation.  Better primers will require abrasive blasted surfaces rather than power tool cleaning.  Ensure suitable, compatible undercoats and top coats are specified elsewhere.  Also check the manufacturer's literature.

 

There may also be a need to cover the situation where steelwork might be left exposed to the weather for a protracted period.  Other special considerations include suitability of the selected primer under fireproofing materials or coatings.

3.23
PATCH PRIMING

Clean and prepare areas of damaged priming and areas left clear for site jointing to a standard comparable with the shop cleaning specified. Degrease to remove chemical fume deposits resulting from welding as well other contamination. Apply priming coat/s 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 lapsed before the final coating system is applied.

3.24
PRIOR TO INTUMESCENT COATING APPLICATION

Confirm surface preparation is in accordance with Altex 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.

3.25
APPLICATION OF INTUMESCENT COAT - GENERALLY

Apply selected Altex intumescent coat/s to coating manufacturer's 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 may be required to achieve the nominated dry film thickness.

Amend paint system selection information to include two finish coats if topcoat application is on-site and will be via roller and/or brush.

Important Note: Colours of LRV 25 and below are deemed to be dark and could be problematic. This also applies to interior steel exposed to sunlight such as atrium locations. Check with Resene or AltexTechnical for further clarification.

3.26
SITE REPAIR METALLIC / MIOX FINISHES

Spray application (conventional or HVLP) on site is recommended for repair and touch up of MIOX or Metallic finishes.

3.27
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, plus finish coat if required.

 

For galvanized bolts allow to degrease, abrade, and apply an approved primer coat prior to the intumescent coating of galvanized bolts.

Contact Altex Coatings Ltd for FR Galvanized Bolt painting specification.

3.28
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 Altex Coatings Ltd. If DFT for fire rated sections are not detailed within, contact Altex Coatings Ltd for details. Refer to SELECTIONS for details.

3.29
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.

3.30
APPLICATION OF TOPCOAT - GENERALLY

For systems with decorative and/or protective (non-intumescent) topcoat, lightly abrade intumescent coat to provide a key. Apply topcoat / coats by spray, brush or roller in accordance with the relevant product Altex Technical 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.

3.31
APPLICATION OF TOPCOAT - ARCHITECTURAL FINISH

For systems with decorative and/or protective (non-intumescent) topcoat, if a high-quality aesthetic finish is required, a thorough sand of the Intumescent coating is recommended prior to applying the topcoat. 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.

3.32
WEATHER PROTECTION & SEAL COATING OF INTUMESCENT COATED STEEL SECTIONS

Unsealed Nullifire SC601 will not withstand prolonged rain/water contact, even under optimum curing conditions during construction. Where exposure to weather, rain and/or water contact may occur, temporary protection must be supplied. Application of Altex Pro-Seal intumescent sealer coat will provide weather protection during construction once the required dry film thicknesses are achieved (refer to Altex Coatings).
Also apply Altex Pro-Seal intumescent sealer to Nullifire SC601 in the following situations:

  • when shop applying the intumescent or to mitigate the risk with water, rain or weather contact while in laydown areas or during on-site construction.
  • when steel sections are adjacent to glazing which will be in direct sun contact
  • to promote the hard cure of Nullifire SC601
  • to permit the application of a wide range of architectural finishes.

There may also be a need to cover the situation where steelwork might be left exposed to the weather for a protracted period.  Other special considerations include suitability of the selected primer under fireproofing materials or coatings.

3.33
PROTECTION OF COATED STEEL SECTIONS

Ensure that unsealed Nullifire SC601, unsealed Nullifire® SC902, Nullifire® SC802, and Southwest Type 5 GP coated steel sections are not exposed to any water, rain, or moisture contact both during application as well as during the design life (refer to Altex Coatings).

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:
