How to Remove Powder Coating from Metal – Different Methods

Powder coating is a type of paint that is applied in a powder form and then cured, typically with heat. It is very durable and can be tricky to remove. When you have metal objects coated with powder coating, you may wonder how to remove them.

You can remove powder coating in a few different ways. The most common method is to use a chemical stripper, which will dissolve the powder coating and allow you to wipe it away. However, this method can be quite messy and dangerous, so follow the directions carefully.

If you want a more environmentally friendly option, try sandblasting or using a heat gun. These methods will take longer than using a chemical stripper, but they won’t damage the metal underneath the powder coating. Here I will talk about all the possible methods with a step-by-step process.

Method 1: Remove Powder Coating Using Chemical Stripper

Powder coating can be removed using chemical strippers, which is dangerous and toxic. We recommend that you hire a professional to remove the powder coating. However, if you are confident and have the proper safety equipment, you can remove powder coating using chemical strippers. Here are the step-by-step instructions:

Things You Will Need:

  • Chemical stripper (Benco B17 Powder Coat Remover Is Recommendation)
  • Protective clothing
  • Rubber gloves
  • Goggles
  • Face mask
  • Ventilation

Step 1: Clean The Surface

Start by cleaning the surface from which you want to strip the powder coating. This step is crucial because it will help the stripper work more effectively. Use a degreaser or soap and water to clean the surface. Renovate All also offers a product called Prep-All, specifically designed to remove grease and oil from surfaces.

Step 2: Apply The Stripper

Once the surface is clean, you can apply the stripper. Make sure that you are wearing the proper safety equipment before you start. Chemical stripper is very dangerous and toxic. Use a paintbrush or a sprayer to apply the stripper to the surface. You want to ensure the stripper is evenly applied to the entire surface.

Step 3: Wait For The Stripper To Work

After you have applied the stripper, you need to wait for it to work. The time that you need to wait will depend on the type of stripper that you are using. After the stripper has time to work, you can remove the powder coating.

Step 4: Remove The Powder Coating

You can use a variety of methods to remove the powder coating. You can use a putty knife, a wire brush, or sandpaper. You want to be very careful when removing the powder coating. If you are not careful, you can damage the surface underneath.

Step 5: Again Clean It

After you have removed the powder coating, you need to clean the surface. Use a degreaser or soap and water to remove any residue from the stripper. Once the surface is clean, you can apply a new coat of powder coating.

Important Note:

The most significant advantage of using a chemical stripper is its effective and inexpensive method. But you must be careful because the chemical is toxic, so wear precautions before applying. It can also damage the surface if you are not careful.

Method 2: Eliminate Powder Coating With Heat Or Thermal Removal

Although chemical stripping is effective, it’s toxic to human health and the environment. So another alternative is Thermal removal or heat stripping. In this method, the powder coating is removed by using heat. This method is also widely used to remove powder coating from metal surfaces. Let’s know about the steps

Method 3: How to remove Powder coating With an Abrasive Blasting System?

When you need to remove powder coating from big parts and components, the best method is an abrasive blasting system. This system uses an abrasive media, typically sand, to remove the powder coating from the surface of the parts.

But it can be an expensive method to use, and it can also be dangerous if not done correctly. Here is how to do it right.

Step 1: Find A Shop Or Service Provider

If you don’t want to do it yourself, the first step is finding a shop or service provider specializing in abrasive blasting. They will have the equipment and experience necessary to do the job right. And if you need to deal with this type of work regularly, purchasing a blasting system can be worth the investment.

Step 2: Prepare The Parts

Once you have found a provider, the next step is to prepare the parts for the process. This includes removing any paint or other finishes that might be on the surface of the parts.

Step 4: Start The Abrasive Blasting Process

Once everything is set up, the next step is to start the abrasive blasting process. This is done by turning on the compressor and opening the valve on the blast nozzle. The abrasive media will then be forced through the nozzle and onto the surface of the parts.

Step 5: Clean Up The Parts

Once the process is complete, the next step is to clean up the parts. This includes removing any residual media from the surface of the parts. Don’t forget to remove any dust on the surface. This can be done with a vacuum or other cleaning solution.

Which Method Can You Apply To Remove Powder Coating At Home?

When you need a small metal object powder coated, you might not want to take it to a professional powder coating company.

You can remove the powder coating with a heat gun, which will strip the powder coating off the metal so that you can powder coat it again or paint it.

  • Step 1: Place the object you want to strip on a heat-resistant surface.
  • Step 2: Turn the heat gun on to its highest setting.
  • Step 3: Hold the heat gun about 6 inches away from the object, and move it back and forth over its surface.
  • Step 4: As the powder coating begins to blister and peel, use a putty knife or other sharp object to scrape the powder coating off.
  • Step 5: When all the powder coating has been removed, allow the object to cool before powder coating or painting it.

The best thing about this method is it is relatively easy and inexpensive. You can do it yourself at home without spending much money.

What To Consider Before Applying Any Of  These Methods?

Before deciding which method will be best for you, you must consider the following:

  • Type of powder coating
  • Size and shape of the object
  • The thickness of the powder coating you need to remove
  • Sensitivity of the surface
  • Amount of time you have to remove the powder coating
  • Cost of removal method

Each of the methods we described in this content is effective. However, without doing your research beforehand, you may incur high costs.

For example, chemical stripping is a viable option for most types of powder coating. However, if you have a large area to cover, the chemicals required for this method can be expensive to purchase and dispose of.

In that case, abrasive blasting might be a more viable option. So, considering facts will help you choose the best project method.


Powder coating is a popular coating process that many companies use to get the best finish for their metal products. It is a relatively inexpensive process with a long shelf life because the paint is embedded in the powder.

The best way to remove the coating without damaging the underlying metal is to remove the powder with a chemical stripper or an abrasive blasting system.

However, Laser Removal is the quickest way to remove powder coating for a large metal piece. If you don’t hesitate to spend more money, you can use laser removal. Keep in mind always take precautions while following any removal method.
