The compound forming the rust. It keeps reacting as long as oxygen and moisture reach it.
Rust stopped, not just painted over.
Surface, pitting, and structural corrosion each get a different protocol. We grade the rust first, then convert and seal it for LA's coastal and inland climates.

Rust on a metal fence is a chemical process, and treating it correctly starts with identifying what stage it's in.
We grade the corrosion first. Then we select the treatment sequence, phosphoric acid conversion, zinc-rich primer, and topcoat, in the correct order with proper dry time between each stage. Every step is documented. Nothing is skipped to save time.
This service is built for homeowners and property managers who want rust stopped, not just painted over.
Phosphoric acid treatment neutralizes what's already there, so we're not painting over an active reaction.

Applied to all active rust zones after proper surface preparation.
A non-reactive compound. The electrochemical corrosion process stops here.
That is a different result than painting over orange rust. Paint over active rust traps the ongoing reaction underneath the coating, and it keeps corroding from below.
Most fences need more than one grade addressed on the same panel.
One pattern repeats constantly: a fence that looks like it has surface rust on the posts has active pitting on the bottom rail where water pools. Surface rust and pitting are not the same problem, and they don't get the same treatment.
Responds well to phosphoric acid treatment. The converter reaches the iron oxide directly and the reaction stops there. No mechanical prep needed.
Once metal has pitted, loose scale has to be mechanically removed before any converter is applied. Applying phosphoric acid over loose scale traps it, and that trapped scale keeps corroding from underneath the fresh coating.
The assessment step exists precisely because conditions vary, sometimes panel to panel on the same fence. After ten years of working on iron fences across LA, I can read a fence before I open a container. That skill matters more than any product label.
Customers ask whether skipping the zinc-rich primer makes a real difference. It does.
Zinc acts as a sacrificial metal: it corrodes preferentially, protecting the iron or steel beneath it. That's galvanic protection. And topcoats fail eventually, which is exactly when it matters.
The topcoat is the only barrier between treated metal and oxygen. Skipping the primer means the converter layer is exposed the moment the topcoat chips.
Zinc beneath the topcoat gives the system a second line of defense. Each stage protects the stage before it.
Los Angeles does not have one corrosion environment. It has at least two.

Salt is an electrolyte. It speeds up the electrochemical reaction that turns iron into iron oxide, and the marine layer carries salt-laden moisture inland each morning.
Flexible urethane, which handles salt air and temperature movement. Flexibility reduces cracking from temperature shifts.

Intense summer heat drives existing surface rust deeper into the metal between rainstorms. Cycling through dry summers and wet winters stresses paint films, and coating failures let oxygen back in.
Epoxy, which provides harder film resistance against high UV exposure and heat.
The zinc-rich primer is applied in both environments. Topcoat selection is the variable that changes with the address. Our crew covers both, and the protocol adjusts to what the fence actually needs rather than a one-size approach applied everywhere.
A documented, staged process. No shortcuts, no skipped steps.
The three stages are the same on every fence. The products and prep intensity adjust to match the metal.
We walk the full fence line. Every post, rail, panel, and bottom edge gets examined and classified as surface oxidation, active pitting, or structural metal loss. Zones of each grade are marked before any product is opened.
Surface rust zones receive direct phosphoric acid treatment. Active pitting zones get mechanical scale removal first, then conversion. We never apply converter over loose material, and dry time is observed fully before primer is touched.
Zinc-rich primer goes on first, over every treated zone, with full cure before the topcoat. The finish coat is selected for the fence's specific environment. The system is designed to last, not just look finished on the day we leave.
