How do I prepare a surface for the International Interprotect?
Steel
- Thoroughly degrease with suitable thinner/cleaner using the 2 cloth method.
- Blast damaged or corroded areas to near white metal surface as per AS1627.4 Class 2.5.
- If blasting is not possible, grind with 24-36 grade abrasive discs to bright metal surface with 50-74 microns anchor pattern.
Aluminium
- Thoroughly degrease with suitable thinner/cleaner using the 2 cloth method.
- Low pressure grit blast using aluminium oxide or a copper free equivalent.
- If blasting is not possible, power disc with 24-36 grade discs.
- After being degreased the surface may be sanded on small areas with aluminium oxide papers.
- After drying, pre-prime with Etch primer
Epoxy Primers
- Sweep blast or abrade with 280 grade abrasive paper.
Epoxy Fillers
- Sand with 60-120 grade abrasive paper.
- Do not wipe down any epoxy fillers with solvent.
Ferro-cement
- Allow to cure for at least 28 days above 20℃ (68℉).
- Ensure structure is free from moisture.
- Remove all efflorescence and other surface contaminants.
Bare GRP / Composite
- Ensure all waxes & uncured resins are removed.
- Sand with 80-180 grade abrasive paper.
Gelcoats
- Sand to remove oxidation and gloss.
- Avoid cutting too deep into the surface which may result in small air bubbles being exposed.
Zinc / Galvanised Steel
- On new surfaces, thoroughly degrease with suitable thinners using the two cloth method.
- Oxidised surfaces will require mechanical abrasion to clean thoroughly.
Lead
- Thoroughly degrease with suitable thinner/cleaner using the 2 cloth method.
- Rub down with an emergy cloth or power wire brush.
- Pre-prime using Etch primer where appropriate.
