What type of primer would you use for surface with rust?

When dealing with a surface that has rust, it's important to use a primer specifically designed to inhibit further rusting and promote adhesion of subsequent paint layers. Here are two common types of primers suitable for surfaces with rust:

Rust-Inhibitive Primer:

Purpose: Rust-inhibitive primers are specifically formulated to stop the corrosion process on rusted surfaces and prevent further rusting.
Composition: These primers often contain corrosion-inhibiting additives such as zinc, phosphate, or other rust converters. Some may also have active ingredients that chemically react with rust to create a stable surface for painting.
Application: Clean the surface by removing loose rust, dirt, and contaminants. Apply the rust-inhibitive primer directly onto the rusted areas. It typically forms a protective barrier that helps prevent the rust from spreading.
Zinc-Based Primer:

Purpose: Zinc-based primers are effective in preventing rust on metal surfaces. Zinc provides sacrificial protection, meaning it corrodes preferentially to the underlying metal, helping to shield it from rust.
Composition: These primers contain a high percentage of zinc particles, often in the form of zinc dust or zinc phosphate.
Application: Clean the surface and remove loose rust. Apply the zinc-based primer directly to the rusted areas. The zinc content helps protect the metal substrate, and the primer promotes adhesion for subsequent paint layers.
Application Tips:

Always follow the manufacturer's instructions for the primer you choose.
Remove loose rust and scale mechanically (with wire brushes or sandpaper) before applying the primer.
Ensure the surface is clean and free of contaminants before priming.
Apply the primer in thin, even coats, allowing sufficient drying time between coats.
Keep in mind that the effectiveness of the primer depends on proper surface preparation. If the rust is extensive or the metal is severely corroded, it may be necessary to address those issues before applying the primer. Additionally, for best results, follow the primer with a high-quality paint suitable for the intended use and environmental conditions.
