quick Overview
RostGuard™ is a cutting-edge rust prevention solution designed to protect metal surfaces from corrosion. This innovative, eco-friendly formula halts corrosion while preparing the surface for over-coating, eliminating the need for abrasive rust removal when used with RostTech™ water-based trust converter.
RostGuard™ is non-toxic and combines superior corrosion-inhibiting technology with a robust priming capability. It ensures long-lasting performance and enhanced adhesion for finishing coatings. RostGuard™ is the trusted solution to effectively prevent rust creep. With its unmatched performance, it’s the ideal choice for protecting your valuable assets from corrosion.
Application Method – Apply by Brush or Spray
Thinning – No more than 10% for spraying

Mild Steel
- Use AlgenTech™ to sanitize the roofing substrate from all grease and oil
- Sandblast steel back to bright metal, ensure all sanding dust is removed
- Apply 2 coats RostGuard™ allowing 45 minutes at 25°C to dry between coats
- Apply top coats
Previously Painted Mild Steel
- Remove all loose, peeling paint (cross-cut test) – where paint has been removed back to metal, sand metal to a bright finish and edges to scar zero
- Remove all rust, using RostTech™ Rust Converter
- Prime the exposed metal only, with 2 coats RostGuard™ – allow to dry between coats
- Apply top coats
New Galvanized Iron
- Use AlgenTech™ to sanitize the roofing substrate from all grease and oil
- Remove all rust from galvanized iron surface, using RostTech™ Rust
- Converter Apply 1 coat RostGuard™
- Apply top coats
Previously Painted Galvanised Iron
- Remove all loose, peeling paint (cross-cut test) – where paint has been removed back to bare metal, sand metal to a bright finish and edges to scar zero
- Remove all rust, using RostTech™ Rust Converter
- Apply 1 coat RostGuard™ to areas where rust was converted – allow to dry
- Apply 1 coat RostGuard™ to all exposed galvanising, resulting in 2 coats where rust was converted
- Apply top coats
Primed Steel 10m2/L
1-2 Coats depending on the surface material (See spec sheet for specific detail)
