Roof Rust Treatment South Africa | Metal Roof Rust Repair

Whether you need to manage existing rust, prevent corrosion, or both, we have the solution. Our rust management systems feature RostTech™, which converts rust into stable, inert metal before being coated with next-generation liquid rubber technology that has built-in rust prevention.

The unique ingredient, RostGuard™, is a non-toxic, anti-corrosive rust inhibitor recognised as the best-performing water-based, anti-corrosive primer available. It creates a durable barrier against moisture and oxidation. This dual-system approach ensures superior rust prevention and extends the longevity of surfaces.

RostTech™ Rust Converter

Our full function, water-based rust converter and metal roof rust treatment, that penetrates deeper than standard converters and converts rust into a stable, inert ferric phosphate compound.

Rust treatment bucket for waterproofing and rust prevention on rubber roofs, metal surfaces, and structures. High-quality water-based rust converter for durable protection.

High-quality liquid rubber paint for roofing, waterproofing, and rust prevention, ideal for metal and slate surfaces, offers durable protection with Mold Guard technology.

Liquid Rubber Paint with RostGuard™

Liquid Rubber Paint with Rust Prevention is a next-generation, water-based acrylic elastomeric coating designed to provide superior waterproofing and corrosion protection in one product. This superior corrosion-inhibiting formula ensures excellent adhesion to metalsurfaces while forming a seamless, flexible, and durable waterproofing membrane. Engineered for long-lasting protection, it prevents water penetration, and shields metal surfaces from rust and degradation.

Rust Management

Rust and corrosion are major concerns for roofing and structural steel, leading to deterioration, costly repairs, and potential safety hazards. Exposure to moisture, harsh weather, and oxidation can weaken metal surfaces over time, compromising their strength and longevity. We understand these challenges and offer specialized rust treatment solutions to protect your investment and extend the life of your metal structures.

Our comprehensive rust management system begins with an advanced rust converter, RostTech™, which neutralises existing rust, transforming it into a stable, paintable surface. This highly effective treatment eliminates the need for additional grinding and sanding. The surface is immediately ready for priming and overcoating—saving time and labor while ensuring a smooth application process.

We then apply a high-performance liquid rubber coating with built-in rust inhibitors (LRP with RostGuard™), creating a seamless, waterproof barrier that prevents future corrosion. This dual-layer protection is versatile and can be applied to all types of metal roofs (even previously painted ones), structural steel, and industrial frameworks, ensuring long-term durability and resistance against the elements.

All the products used in our rust management system are environmentally friendly, include mold inhibitors, and are free from harmful chemicals. They are designed to exceed their warranty period.

We stand by the quality of our work, offering a 10-year warranty on both product and workmanship, giving you peace of mind that your roofing and structural steel are protected for years to come.
