Armourspray is only suitable for coastal environments >10m from the high tide line and is NOT suitable in strongly acidic environments so the pH must be between 5 and 9. Please refer to the ‘Interior and exterior environments close to liquids other than coastal, river and lake salt water environments’ section for warranty implications in such environments.

*Warranties are only valid when applied by a Dulux Accredited or Dulux Prime Accredited Powder Coater to the warranty specification on recommended projects, and subject to specified warranty terms and conditions. Warranties for Armourspray apply to the stocked products listed here and CustomColours on request only.

^ The Alumi Shield and Steel Shield Colour Warranties are not applicable to Armourspray clear products.

The Alumi Shield Durability and Steel Shield Corrosion Warranties only apply to Armourspray clear products when applied over Dulux Duralloy +PLUS, Protexture, Duratec, Electro & Charisma powder coatings. The Alumi Shield Durability and Steel Shield Corrosion Warranties do not apply to Armourspray clear products when applied over any other products or directly to an aluminium or steel substrate.

When overcoating Dulux powder coatings with Armourspray clear products, the durability or corrosion warranty relating to the clear topcoat will only apply. Any durability, colour or other warranties relating to the overcoated Dulux powders coatings will no longer apply.

Variables beyond the reasonable control of Dulux such as graffiti type and time elapsed prior to graffiti removal, can impact the performance of the Coating System. If the Coating System has been graffitied and there is a failure in the graffitied area, the warranty will be limited to the areas not impacted by the graffiti.

Pre-treatment of Aluminium

Pretreatment Standards

The pre-treatment process must be capable of meeting the performance outputs as described in AS3715 and AAMA 2603

Compliance to appropriate process parameters is essential in ensuring compliance to etch, conversion coating weights (time/concentration) and conductivity of the final rinse.

Etch

The etch process is a very important stage of pre-treatment and close consultation with your pre-treatment supplier is strongly recommended to ensure optimum adhesion & corrosion resistance is obtained. As an approximate guide:

An etch rate of >1gm/m2 , is recommended for Armourspray projects, but etch rate advice from pre-treatment suppliers should be taken into consideration.

Conversion Coatings

This is the next pre-treatment process for aluminium to ensure that it is suitably prepared for coating.

Chrome conversion weights must be a minimum of 431mg/m².
Chrome-free conversion weights – refer to your pre-treatment supplier as currently no standards address chrome-free.
Chrome-free conversion coatings should be applied and maintained in accordance with the manufacturer’s instructions.
When changing from chrome to chrome-free your accreditation will require reapplication immediately. Warranty applications through this period will need to be monitored, tested and approved individually.

Final Rinse

Final rinse is to ensure optimum surface preparation prior to coating.

Final rinse water run-off from the extrusion shall have recommended conductivity of less than 80 micro Siemens/cm.
Pre-treated aluminium must be powder coated within the time specified by the pre-treatment supplier – this is generally within 16 to 48 hours.
The entire area of the aluminium shall be properly pre-treated, appropriate spacing devices should be used.

Handling

Care should be taken with handling to ensure health and safety measures are met and that the substrate is not contaminated.

Pre-treated sections must never be handled with bare hands. Clean and lint free cotton gloves must be worn at all times when handling pre-treated sections.

Dry Off Oven (if applicable)

If your site uses a dry off oven to assist in the pre-treatment process, consult your pre-treatment supplier for advice, but generally;

< 75° C for chrome pre-treatment,
< 120° C for chrome-free pre-treatment.
Applicators must be able to demonstrate compliance with this specification.

Pretreatment Standards

The pre-treatment process must be capable of meeting the performance outputs as described in AS3715 and AAMA-2604

Pre-treatment of Steel

Steel substrates shall be prepared as follows:
1. Wash and degrease all surfaces to be coated in accordance with AS1627.1 with a free-rinsing, alkaline detergent, in strict accordance with the manufacturer’s written instructions and all safety warnings.
2. Wash with fresh potable water and ensure that all soluble salts are removed in accordance with AS 3894.6 methods A&D.
3. Grind all sharp edges with a power tool to a minimum radius of 2mm.
4. Power tool clean welds to AS1627.2 Class 2 to remove roughness. Remove filings, preferably by vacuum or compressed air.
5. Abrasive blast clean all steel surfaces to be painted in accordance with AS1627.4 to visual standard AS1627.9 Class 2.5 (equivalent to ISO8501-1, Sa 2.5: Very Thorough Blast-Cleaning). Use a medium that will generate a surface profile of 35 to 65 microns (as tested to AS3894.5 Method A.) In situations where it is not possible to prepare your item on all surfaces as described above, for long term protection against corrosion it is strongly recommended whenever possible, that an alternative substrate such as, aluminium be considered.
6. The steel is to be stored in an area which is clean and dry
7. The steel must be coated within 4 hours of blasting.

How to clean your powder coating in 3 easy steps

1. Carefully remove any loose surface deposits with a wet sponge by gently rubbing.
2. Clean by gently rubbing the surface with a soft brush (non-abrasive) and a dilute solution of a mild detergent, e.g. pH-neutral liquid hand or dishwashing detergent in warm water to remove dust, salt and other deposits. For stubborn stains use only recommended solvents on the affected area, e.g. Isopropyl alcohol (IPA) or methylated spirits and rinse off with clean water. Do not use other aggressive solvents.
3. Rinse the surfaces with clean fresh water after cleaning to remove all residues.

Additional advice for graffiti removal

If the steps outlined above do not remove graffiti from affected areas, follow these steps:
4. Either spray graffiti remover GuardIt® Soy Safe Sensitive or apply GuardIt® Soy Allstone Gel using a soft brush to the affected surface area and leave for at least 5 minutes. Follow the safety instructions listed on the GuardIt® product label. Visit guarditsolutions.com.au for product availability.
5. Using a clean damp soft cloth gently wipe the surface and rinse with clean fresh water to remove all residue.
6. If graffiti is still visible repeat steps 4 and 5 again.
