When To Choose Naturally Oxidized Rust or Corten Rust
Once of our most popular paint effect is the RUST effect. We have two different products that each have unique features, so this page will distinguish between the two effects.
Before comparing the two effects, here are the key differences. RUGGINE XR.01 is a Naturally Oxidized Rust Effect produces a one-of-a-kind finish that is slightly different on each surface due to the natural oxidization reaction to create a real rusted surface. The Corten Rust AX.01 is a Realistic Imitation of the Corten color that develops the typical rusty look of rusted Corten steel.

Corten Rust Effect PaintThis chart explains the differences between the rust effects and the application techniques.
| FEATURE | RUGGINE XR.01 RUST EFFECT | CORTEN EFFECT PAINT |
| Type of Oxidation | Real iron particles are naturally oxidized on the surface | Simulated oxidization with oxide and iron hydroxides along with microspheres to create a realistic rust effect. |
| General Resistance of the Finished Surface | All oxidized surfaces have low resistance until the transparent topcoat is applied Apply a Matte topcoat for increased resistance Outdoor use: contact the office to discuss your project | The surfaces are very resistant to both cleaning and to UV light with the application of a Matte topcoat Outdoor use: very resistant |
| Simplicity of the Application Cycle | The application cycle for the Naturally Oxidized Rust includes: – Primer for your surface – Iron Base – Oxidation or Activator – Washing with water – Rust Blocker – Transparent Topcoat | The application for Corten Rust includes: – Primer for your surface – Corten Rust Effect Base – Transparent Topcoat |
| Vertical Surfaces | When the Oxidizer or Activator is used on a vertical surface, the liquid will run down and make natural looking streaks; the amount of rust oxidization will be lighter If you oxidize a flat or horizontal surface, oxidizer will make more irregular patterns of rust with stronger rust colors | The vertical surfaces can be painted without any problems This paint is ideal for irregular, curved or complex surfaces like hand railings and urban décor |
| Reproducibility | Every finished surface will be different because of the natural oxidization process; this feature is sought-after and appreciated | The surfaces can be easily reproduced if the quantity of paint and application method are kept the same |
