Is it Possible to Powder Coat Rusted Metal?

Is it Possible to Powder Coat Rusted Metal?

Powder coating is a very durable metal finishing method, and it can certainly prevent rust from forming, but is it possible to apply powder coating to a surface that is already rusted? While the answer to this question is technically yes (it is not impossible to apply powder coating to a rusted surface), it should never be done. Applying powder coating over rust will result in a very poor finishing job. In the short term, rust under powder coating will cause immediately noticeable surface imperfections. In the long term, rust will continue to grow underneath the powder coating, which may cause the powder coating to fall off completely as the surface deteriorates. At Secoa, we know that rust will ruin a coating job. That’s why our specialty finishing services include metal preparation. Proper surface preparation is an essential part of the coating process; removing contaminants (such as rust) before applying powder coating helps ensure a pristine finish. Secoa offers multiple metal preparation services, including blasting and burn-off. Thanks to our top of the line equipment, we have the capability to strip and prepare a wide range of both ferrous and non ferrous substrates, including iron, steel, aluminum, magnesium, titanium, and more. We always remove rust from a surface before applying a coating in order to achieve the highest quality results.

Eco-Friendly Metal Finishing: Powder Coating

Are you looking for an eco-friendly metal finishing option? If you answered yes, then you should consider powder coating. Powder coating has a plethora of features that make it a top tier choice for all kinds of finishing applications; one such feature is its “green” nature. Powder coating is a lot better for the environment than many metal finishing alternatives.

Powder Coating and Air Pollution

One major reason powder coating is considered eco-friendly is because it doesn’t contribute to air pollution. Many other finishing options, like paint, contain volatile organic compounds (VOCs), which are eventually released into the air. When VOCs are released, they cause damage to the ozone layer. Powder coating does not emit VOCs, which means it doesn’t cause air pollution by releasing toxic fumes into the environment.

 Powder Coating and Hazardous Waste

In addition to producing VOCs, wet paint produces a lot of hazardous waste, because it often requires reworks that involve solvents. These solvents produce harmful fumes while in use, and then need to be disposed of (at which point they are considered hazardous waste). Retouching powder coating does not require any harsh chemicals, and since its inert on its own, the powder coating process does not produce any hazardous waste.

Reduce, Reuse, Recycle

During the powder coating process, there is always some powder that fails to adhere to the surface. Rather than being thrown out, this excess powder can be reclaimed and used again later. Therefore, powder coating is a good choice for anyone concerned about unnecessary waste.

What’s the Difference Between Corrosion and Rusting?

What’s the Difference Between Corrosion and Rusting?

In the world of metal finishing, products are often described as anti corrosion coatings, anti rust coatings, or both. Using this pair of descriptions for one product may seem redundant, as the terms corrosion and rust are often assumed to be direct synonyms, and used interchangeably as a result. However, there are a few differences between corrosion and rusting.

Defining the Terms

Technically speaking, corrosion is the process in which oxidation caused by chemical or electrochemical reactions causes a material to deteriorate, while rusting is the oxidation of iron that has been exposed to air and moisture. Rust is a type of corrosion, but not all corrosion is rust.

What Does it Look Like?

Rust has a very distinctive orange-brown color, and because rust is a type of corrosion, some corrosion does, too. But, not all corrosion is orange-brown. Some types of corrosion are other colors, like green or blue.

What Does it Affect?

One of the key differences between corrosion and rusting is the material affected. Corrosion can occur on a variety of surfaces, including metals, ceramics, polymers, and even wood. Rusting, however, occurs only on iron and iron alloys.

So, using the term “anti corrosion coating” indicates that a product can be used for applications involving a wide variety of materials, while using the term “anti rust coating” explicitly indicates that a product will work well for applications that involve iron or iron alloys.

Though most coatings that prevent rust will likely prevent other types of corrosion as well, it may prove useful to be aware of this distinction.

What is the Cause?

Another notable difference between corrosion and rust is cause. Corrosion can occur on particular surfaces when they are exposed to air or specific chemicals. Rusting occurs when an iron or iron alloy is exposed to both air and moisture.

In Conclusion

Overall, the differences between rust and corrosion are minimal, but they do exist. It is probably safe to assume that most of the time, anti corrosion coatings will prevent rust, and anti rust coatings will prevent other types of corrosion.

This is certainly true of our products at Secoa Metal Finishing. Our protective coatings are great for preventing many types of corrosion, rust included. If you would like to learn more about our corrosion resistant, anti rust coatings, give us a call at (706) 383-2893 or send an email to

Comparing the Benefits of Anodizing, Painting, and Powder Coating

There are many different types of metal finishing; some of the most popular are anodizing, painting, and powder coating. Choosing the right type of coating for your application can be essential to achieving the desired results. If you have a piece of metal that needs to be coated, you may find yourself wondering, “Which is best? Anodizing, painting, or powder coating?”


Anodizing is an electrochemical process that can be used to form a protective coating of oxide on a metal surface. One thing that sets anodizing apart from other finishing methods is that the coating it creates is actually a part of the metal, so it cannot peel or flake. As a result, anodizing makes metal surfaces extremely durable. Anodizing is great for applications that require high levels of corrosion resistance and abrasion resistance. Anodizing also makes metal surfaces non-conductive, which can be useful in certain circumstances. In most cases, anodizing is restricted to aluminum substrates only.

Powder Coating

Powder coating is a metal finishing process that involves applying dry powder to a metal surface, and then heating the powder until it cures. There are several reasons one might choose powder coating as a metal finishing method. Though powder coated surfaces are generally not as durable as anodized surfaces, they are still extremely resistant to corrosion, abrasions, and general wear and tear; powder coating is a quick and simple process, which makes it convenient; and powder coating comes in a huge variety of colors.


Using wet paint is the most conventional metal finishing method. Though paint is much less durable than powder coating or anodizing, it does have its advantages. For example, paint can be used to coat surfaces that can’t be heated; it comes in an even more impressive array of colors than powder coating; and it is often very affordable.

The Verdict

So, which is best: anodizing, painting, or powder coating? Well, the answer is that there is no clear answer. Each of these finishing methods is best for its own specific range of applications. If you need extreme durability, you may want to look into anodizing. If you need corrosion resistance, but you also want a lot of color choices, powder coating may be your best option. If you just want a classic coating that is simple and cost-effective, painting is the way to go.

If you are seeking out metal finishing services, make sure to do your research and choose the process best suited for your application.

Powder Coating vs Galvanizing: A Comparison of Steel Finishing Methods

Steel is a remarkably strong material, and as a result, it is commonly used for a wide variety of industrial applications. However, it is also susceptible to things like corrosion. As such, it is important to apply protective coatings to structures and equipment made of steel. Two of the most common metal finishing methods for preventing damage to steel components are powder coating and galvanizing.

Powder Coating

Powder coating is extremely popular in the metal finishing industry. The powder coating process involves applying a dry, electrostatically charged coating to a surface, and then curing it until a protective layer is formed. There are many benefits using powder coating on steel components. Powder coating is extremely durable, and can protect a surface from chipping, abrasions, corrosion, and chemical damage, among other things. It is also available in a wide array of colors and textures.


Galvanizing is a metal finishing process that involves dipping steel in molten zinc, which creates a metallurgic bond between the two materials. Galvanizing results in a layer of zinc that protects the steel from the elements and prevents it from succumbing to corrosion. Galvanized steel can last for 50-100 years, and requires very little maintenance, which makes it cost effective in the long-term.

Which Is Best?

So, which method is better for finishing steel? Powder coating or galvanizing? The truth is, neither of these metal finishing methods is inherently superior to the other. While powder coating is the best choice for some applications, galvanizing is better for others.

For example, because powder coating offers so many more color options than galvanizing, it is a better choice for applications where aesthetics are important. Meanwhile, galvanizing makes steel more temperature resistant than powder coating, and so is better for applications that involve extreme heat or extreme cold.

If you have a steel component that needs a protective coating, do your research to find out which method best suits your application before committing to one or the other.
