Rust: Prevention Tips & Signs That It May Be Time For A Replacement Door

Your exterior doors do more than provide easy access to your business or property. They are an important part of your security system and should be treated with care. That means being conscious of damage or rust that can compromise the security of the door. Take the time to check the condition of all your exterior doors regularly to avoid security issues or the need to replace doors damaged from the effects of rust.

What Is Rust?

Rust is the oxidation of iron and other elements in your metal doors or around the hinges and locks on your doors. Its technical name is iron oxide, and it occurs when the iron in your metal door is exposed to moisture and oxygen. This means exposure to weather can pose the risk of rust on your doors if you do not take the proper precautions.

How Do You Identify Rust?

Rust is easy to identify; it is a rusty-red corrosion that forms on metals that contain iron, such as a steel door. It may look crusty, flaky or simply a big orange-red stain. When wet, rust typically runs, leaving streaks on the door, usually near the hinges or door knobs, but it can appear anywhere on the door where iron is exposed to moisture and oxygen. Initially, rust is nothing more than an ugly blotch on the door, but when left to its own devices it will soon begin to eat away at the metal, compromising the integrity of the door.

Will All Doors Rust?

If you have a metal door, it is subject to rust. While paint or sealer will prevent exposure to moisture, if the paint peels or your door has scratches on the surface, it is likely that it will rust. Wooden or vinyl doors do not rust, but any metal hardware (such as the lock, door knob and hinges) will.

Can You Prevent Rust On Your Doors?

There are several ways to minimize or eliminate rust on your doors.

Install a drip cap. This prevents moisture from rain and snow from collecting on the top of your doors.

Seal the door. Use a rust-proof primer on the door before you paint it. This will help prevent rust from forming if you get scratches on the door, or if the paint chips or peels.
Keep the door clean. Wiping down or washing the door to remove dust and other debris will help prevent rust.

Can You Get Rid Of Rust?

If your door has surface rust that has not deteriorated the metal of the door, there are steps you can take to resolve the issue. Here’s what you need to do:

  1. Scrape the door to remove loose corrosion.
    Use a wire brush to remove any remaining traces of rust.
    Apply a coat of rust-proof primer to the area.
    Complete with a coat of quality paint.
