How to Remove and Prevent Rust on Metal Fencing

A well-maintained metal fence not only enhances the security of your property but also adds to its curb appeal. However, over time, it can start to rust, which can compromise both its functionality and appearance.

If your metal fence has started to rust or you want to take preventative measures before any rust sets in, you’ve come to the right place as in this article, we’re going to cover:

• How to remove rust from metal fences
• How to prevent rust from reoccurring
• Tips for long-term care of metal fences

But before we cover the topics above in greater detail, we’d first like to share with you a couple of common causes of rust on metal fences.

Common Causes of Rust on Metal Fences

Rust forms when iron or steel reacts with oxygen and moisture. This combination ends up producing a reddish-brown coating that corrodes and weakens the material. There are a number of factors contributing to this process:

• Exposure to Moisture: Rain, humidity, and standing water are the primary culprits. Prolonged exposure increases the likelihood of rust development.
• Lack of Protective Coating: When metal is unprotected or the coating wears off, it becomes more susceptible to corrosion.
• Environmental Conditions: Salt-laden air in coastal areas and air pollution in urban environments can accelerate the rusting process.
• Poor Maintenance Practices: Neglecting routine cleaning or inspections allows dirt and moisture to accumulate, creating ideal conditions for rust to form.

Understanding these causes is the first step in protecting your fence against rust.

How to Remove Rust from Metal Fences

Once rust appears, prompt action is essential to minimise damage. Here’s how to tackle it effectively:

Cleaning and Preparing the Area

Start by cleaning the fence to remove dirt, grime, and loose rust.

1. Use a mixture of mild detergent and water to scrub the surface with a soft brush.
2. Rinse thoroughly and allow the fence to dry completely.
3. Inspect the fence closely to identify rust spots and determine the severity.

Proper preparation ensures that rust removal methods are more effective

Manual Methods for Removing Rust

For minor rust spots, manual removal methods are often sufficient. Some manual rust removal methods include:

• Wire Brush or Sandpaper: Scrub the rusted areas with a wire brush or fine-grit sandpaper to remove surface rust. Make sure to work gently to avoid damaging the metal underneath.
• Rust Removal Products: Apply a rust remover or converter to dissolve rust chemically. Follow the product’s instructions carefully, including rinsing and drying the treated area.

Power Tools for Tough Rust

When rust is extensive or deeply ingrained, the use of power tools may be necessary. Some power tools that you may need include:

• Angle Grinder: Attach a wire wheel or abrasive disc to an angle grinder to remove stubborn rust efficiently.
• Drill with Sanding Attachments: Use sanding discs or wire brushes designed for drills to tackle harder-to-reach areas.

Always wear protective gear when using power tools to ensure safety during the process.

How to Prevent Rust from Reoccurring

Once you’ve removed the rust from your metal fencing, preventing its return is crucial. Here are some effective strategies:

Applying Protective Coatings

Adding protective layers to your fence creates a barrier against moisture and oxygen. Some examples of protective coatings include:

• Paint: A high-quality exterior paint shields the metal from the elements while enhancing its appearance.
• Rust-Resistant Primers: Apply a primer before painting to improve adhesion and provide extra protection.
• Powder Coating: This durable finish involves baking a powder onto the metal surface, offering long-term corrosion resistance.
• Anti-Corrosion Sprays: These sprays are quick to apply and ideal for touch-ups or additional protection.

Regular Maintenance and Inspections

Routine care prevents small issues from escalating into significant problems. Here’s what we recommend you to do:

• Inspect the fence periodically for early signs of rust, peeling paint, or damage to protective coatings.
• Clean the fence regularly to remove dirt, debris, and moisture.

Proper Installation Practices

Rust prevention starts with good installation practices. Here are a few installation practices that you should adhere to:

• Ensure that the fence is installed with proper drainage to prevent water accumulation.
• Avoid direct contact between metal parts, as this can create areas where moisture gets trapped.

Tips for Long-Term Care of Metal Fences

To maintain a rust-free fence for the years to come, there are a couple of steps that you should follow, including:

Keep Your Fence Dry

Water is rust’s greatest ally, so minimising moisture exposure is essential. To do that, you should:

• Remove leaves and debris from the fence base to prevent moisture buildup.
• Adjust landscaping to redirect water away from the fence.

Clean the Fence Regularly

Even low-maintenance fences benefit from occasional cleaning, so make sure that you:

• Use a gentle cleaning solution and a soft brush to clean the fence’s surface.
• Rinse thoroughly to remove cleaning residue, which can attract dirt and moisture if left behind.

Consider Professional Treatment

For extensive rust or when the fence requires a fresh finish, hiring a professional isn’t a bad idea. Professionals can sandblast rust, reapply coatings, and ensure the fence is fully protected against future corrosion.

Rust-Resistant Alternatives

While metal fences are durable, there are many different types of rust resistant fence options which are significantly less susceptible to rust. One great example is fence panels made of composite materials.

What makes this particular type of fence a great option is that it combines durability with minimal maintenance requirements, making it a practical choice for busy homeowners.

And the good news is that composite fence panel prices can vary depending on factors such as size, material quality, and design, allowing homeowners to find an option that fits their budget.

Final Thoughts

Rust can diminish the functionality and appeal of your metal fence, but with the right approach, it’s entirely manageable. By understanding what causes rust, taking prompt action to remove it, and implementing preventive measures, you can keep your fence in excellent condition for years to come.

If your fence is beyond repair or you’d like to opt for a rust-resistant alternative that won’t require as much maintenance compared to your current metal fencing, we couldn’t recommend composite fence panels enough.
