Steel substrates shall be prepared as follows:
1. Wash and degrease all surfaces to be coated in accordance with AS1627.9 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.
Electrostatic Spray
Assuming top coat applied within 12 hours:
Partially cure for 3 – 5 minutes at 120-150°C metal temperature.
This partial cure is referred to as a green cure. Green cured metal is prone to chipping/cracking if not handled with care. Ensure green cured metal is protected from mechanical damage caused by unloading/stacking.
Use top coat cure schedule to complete cure of Zincshield®.
A topcoat must always be applied.
It is recommended that Zincshield® be top coated within 12 hours due to a possible moisture uptake of the coating.
