5 Best Paints for Metal Gates & Fences to Prevent Rust

Things to consider when buying paints for metal gates

Owning a property comes with certain responsibilities. One of those is ensuring your metal gates and fences are well-painted to prevent rust and corrosion caused by exposure to the elements.

But with so many paints on the market, it can be tough to decide which type of paint you use on your metal surfaces that can make a big difference in how well they resist rust.

In this blog post, we’ll take a look at some of the best paints to use for metal gates and fences to help keep them looking great for years to come. Stay tuned!

Types of Paint for Metal/Iron Surface

Painting metal gates and surrounding fences is a proactive measure that combines protection, durability, aesthetics, and ease of maintenance to optimize their functionality and appearance. these painted surfaces are easier to maintain, requiring regular cleaning and occasional touch-ups to preserve the finish and ensure continued protection.

Based on the metal surface, their location (whether indoor or outdoor), and their condition, here are some of the best types of paints you can use.

1- Oil-based Paints – Are Most Durable

Oil-based paints are the most durable types of paint you can use for outdoor metal surfaces where longevity and resistance to corrosion are essential.

However, these paints can be a bit tricky to work with because of their high VOCs and smell, so make sure you follow the directions on the can carefully.

You’ll also need to use mineral spirits or paint thinner to clean up your brushes and tools after you’re done painting. So, be sure to work in a well-ventilated area when using oil-based paints, and consider wearing a respirator to minimize exposure to harmful fumes.

2- Aerosol Spray Paint Cans – Give Wide Coverage

Aerosol spray paint cans are easy to use and hence a great option if you need to cover a large area quickly. They offer wide coverage and can be used on both indoor and outdoor metal surfaces.

Just be careful when using them, as they can be difficult to control. Especially if you are a beginner, you may want to practice on a scrap piece of metal before painting your gates or fences.

3- Epoxy-based Paint – Best for Heavy-duty Use

Epoxy-based paints are another great option for outdoor metal surfaces. Due to the epoxy additive in the paint, these paints are very durable, can withstand heavy use, and are resistant to rust and chemicals, making them ideal for use in areas that may be exposed to harsh conditions.

However, epoxy-based paints can be a bit tricky to work with. They have a strong odor and can be difficult to remove if you make a mistake. So, make sure you read the directions carefully before using this type of paint.

4- Water-based Paints – Are Faster Drying And Emits Fewer Fumes

Water-based paints, such as latex and acrylic paint, are a suitable option for indoor and outdoor metal surfaces because they do not release harmful fumes into the air. If you prioritize paint that is less odorous and easier to work with, these are an excellent choice. While they may not be as durable as oil-based paints, they still offer adequate protection against rust and wear.

When painting metal surfaces with water-based paints remember that they can accelerate rust formation if applied directly. To mitigate this risk, it’s advisable to prime the surface with an oil-based primer before using latex paint.

Given metal’s inherent susceptibility to rust, priming is a crucial step in the painting process to enhance adhesion and provide a protective barrier against corrosion.

5- Rust Converter Paints – Help Prevent Rust

Rust converter paints are a great option if you’re trying to prevent rust on your metal surfaces. However, they are slightly more expensive than others.

Rust converter paints are available in both aerosol and brush-on varieties. They work by converting the iron oxide in rust into a protective coating which can help extend the life of your metal gates and fences by protecting them from further rust damage.

Other than the above, there are:

  1. Paint Pens – Ideal for Touch-ups
  2. Paint sticks – For Hard-to-reach Areas
  3. High-temperature paints – Withstand Extreme Heat

What are the Top Brands of Paints to Choose for Metal Objects?

There are many great brands of paint that you can choose from when painting metal objects. Some of the best ones include:

  1. Rust-Oleum- A great option for preventing rust
  2. Krylon- A good choice for both indoor and outdoor use
  3. Valspar- A good choice for durability
  4. Benjamin Moore- A good choice for a high-quality finish

Remember that when it’s time to choose the best types of metal paint that suit your needs, you don’t need all of the above ones. Just one type depending on the location and condition of your surface, will do.

Once you have picked the one, it’s essential to get to work and apply it correctly so that you achieve the best results and ensure the longevity of the paint job.

What is the Best Way to Paint Metal Objects?

The best way to paint metal objects will depend on the type of paint you’re using.

Proper surface preparation, including cleaning and priming if necessary, is crucial to ensure adhesion and durability.

Cleaning and pressure washing will remove any grease, dirt, or other debris that could prevent the paint from adhering properly. And priming will help the paint to stick to the metal better.

Then follow the manufacturer’s instructions for application techniques, such as brushing, rolling, or spraying, and allow adequate drying time between coats. It is typically recommended to apply two coats of paint to the metal. This will help to ensure that the new paint adheres properly and that the color is even.

Be cautious if you are painting over old paint or rust. If the old paint or rust is in good condition, you can sand the surface slightly and then repaint it. However, if the old paint or rust is flaking or peeling, you will need to remove it completely before repainting.

Also, pay attention to environmental conditions, such as temperature and humidity, which can affect drying times and overall finish quality.

If you make a mistake while painting, removing the coating from the metal is possible but the process will depend on the type of paint used. For water-based paints, you can just use soap and water. But for removing oil-based paints from metal, you’ll need to use mineral spirits or paint thinner. And for epoxy-based paints, you’ll need to use strong chemical-based strippers to remove the paint.

Considerations when Buying the Best Paint for Metal

Whether the paint you choose for your metal gates and fences will work effectively or not depends on a few factors which include;

1- Type of Metal

Different types of metals may require specific coatings. For instance, the type of metal that your gates and fences are made of may include wrought iron, aluminum, or steel. They may each have their own compatibility with certain paint formulations so it’s good to ensure the paint you choose is suitable for the type of metal you’re painting.

2. The Climatic Conditions

Next, you’ll need to consider the climate when choosing paint for your metal gates and fences. If you live in an area with extreme temperatures, you’ll need to choose paint that can withstand the heat or cold. And if you live in an area with high humidity, you’ll need to choose a paint resistant to moisture.

Consider the level of exposure to environmental elements such as sunlight, moisture, and temperature variations. Paints designed for outdoor use typically offer better durability and weather resistance.

3. Paint Finish and Color Selection

When selecting the right paint for your metal fences and gates, decide on the desired finish—matte, satin, gloss, or textured—which not only affects appearance but also influences factors like ease of cleaning and resistance to abrasion.

  • Choose a color that complements your property’s aesthetic and blends well with the surroundings.
  • Look for a paint that offers good coverage and can be applied in multiple coats if needed, as thicker paints provide better protection.
  • Consider the application method—brushing, rolling, or spraying—and select a paint formulated for your chosen technique.
  • Lastly, check the drying and cure times to ensure they match your project timeline, balancing efficiency with durability for optimal results.


Selecting the ideal paint for your metal gates and fences can be a straightforward process when you take certain factors into account. By carefully considering the type of metal, the location of the structure, the prevailing climate, and your budget, you can confidently narrow down your options and choose the best paint for your needs.
