You’ve just had a new piece of furniture delivered and you can’t wait to show it off to your friends. But when you go to take the protective cover off, you realize that the powder coat finish is peeling. Now what? Can you paint over a powder coat? The answer is yes – but there are a few things you need to know before you get started. In this article, we’ll discuss the basics of painting over powder coats and provide some helpful tips on how to get the best results.
What is powder coating made of?
Powder coating is a type of finishing that is applied to metals, plastics, and other materials. It is made up of finely ground particles of pigment and resin that are electrostatically charged and then sprayed onto the surface. The powder adheres to the surface and is then cured under heat to create a durable finish.
One of the advantages of powder coating is that it can be applied in a thicker layer than traditional paint finishes. This makes it ideal for surfaces that will see a lot of wear and tear, such as outdoor furniture or playground equipment. Powder coating is also available in a wide range of colors, so you can find the perfect match for your project.[5]
Painting Over Powdered Paint
Cleaning
The first step is to clean the surface. If there is any dirt or grime on the surface, it will need to be removed before painting. You can use a variety of cleaners, but make sure to read the labels and follow the instructions carefully. After cleaning, you should let the surface dry completely before starting to paint.[2]
Adhesion
One of the main concerns people have when painting over powder coating is whether the new paint will adhere properly. Powder coating is a very tough and durable finish, so it can be tricky to get new paint to stick. However, it is possible to paint over a powder coat as long as you take the proper steps to prepare the surface.
To start, you will need to sand down the powder coat until it is dull and roughed up. This will give the new paint something to grip onto. You can use a palm sander or orbital sander for this step.
Priming
If you’ve decided that painting over your powder coat is the right decision for you, then the next step is to prime the surface. This will help the paint to adhere better and create a more even finish. Be sure to use a primer that is designed for use on powder-coated surfaces. Once you’ve applied the primer, allow it to dry completely before moving on to painting.
Paints
If you want to change the color of your powder coated item, or if the original color is fading, you can paint over powder coating. However, it is important to note that painting over powder coating is not always easy and may not produce the results you are hoping for. In some cases, it may be necessary to remove the old powder coating before repainting. Keep reading for more information on whether you can paint over powder coatings as well as helpful tips on how to do so.
The Benefits
Powder coating is a type of paint that is applied as a dry powder and then cured under heat. It is usually used on metal surfaces but can also be used on wood, plastic, and glass.
If you are considering powder coating your project, here are some things to keep in mind:
- Powder coating can be applied to most metals including aluminum, steel, brass, and copper.
- Powder coating can also be applied to some plastics and composites.
- Powder coating is available in a wide range of colors and finishes.
- Powder coating is more durable than traditional paint and can resist chipping, fading, and scratching.
- Powder coating is more resistant to chemicals and salt spray.
Why can’t you just apply paint directly?
The main reason you can’t just apply paint directly is that powder coating is a baked-on finish, and paint won’t adhere to it properly. Even if you manage to get the paint to stick, it’s likely that it will peel off eventually.
Another reason is that powder coating already provides a high-quality finish that is resistant to chipping, fading, and other damage. Adding an additional layer of paint may actually decrease the quality of the finish.[5]
Challenges To Applying Liquid Paint Over Powder Coating
One common challenge is that paint will not adhere as well to powder coating as it does to bare metal. This is because the powder coating creates a smooth, non-porous surface. To help the paint stick better, you can sand the powder coating before painting.
Another challenge is that painting over powder coating can cause the new paint job to chip and peel more easily. This is because the smooth surface of the powder coating makes it difficult for the new paint to grip onto. To help prevent this, you can use a primer designed for use on powder-coated surfaces.
Finally, it’s important to note that painting over powder coating will void most warranties. So if your furniture is still under warranty, you may want to think twice before painting it.[1]
How To Overcome The Challenges Of Applying Liquid Paint Over Powder Coating
One of the main reasons why powder coating is so popular is because it provides a tough and durable finish that can withstand a lot of wear and tear. This makes it an ideal choice for things like metal fencing, car parts, and outdoor furniture.
However, sometimes you may want to change the color of your powder coated item or simply refresh the existing color. In these cases, you may be wondering if you can paint over a powder coat.[1]
Important Considerations Of Painting Over An Existing Powder Coating
You’ll first want to consider a few factors before deciding whether or not painting over powder coating is the right decision for you. These include:
- The age of the powder coating
- The condition of the powder coating
- The type of powder coating
- The color of the powder coating
If you have an older powder coating that is starting to show its age, painting over it may be a good way to give it new life. If the powder coating is in good condition, you may be able to get away with just touch ups here and there. However, if the powder coating is severely damaged, painting over it may not be enough to salvage it. In this case, you may need to strip the old powder.[1]
What Paint Should be Used to Overcoat Powder Coating?
First and foremost, it’s important to use a high-quality paint that is specifically designed for powder coating. Not all paints are created equal and using the wrong type of paint could result in poor adhesion or even damage to the powder coat.
When selecting a paint, be sure to choose one that is compatible with the type of powder coat you are using. For example, if you have a polyester powder coat, you will want to use a polyester-based paint.
It’s also a good idea to select a paint that is similar in color to the powder coat. This will help ensure that the colors match up and create a seamless look.[4]
How Should the Paint be applied?
You should use a good quality primer specifically designed for use on powder-coated surfaces. Apply the primer using a high-quality brush, roller, or sprayer.
It’s important to note that while painting over powder coating is possible, it’s not always necessary. In many cases, simply cleaning and re-powder coating the surface will be enough to restore its original appearance. However, if the powder coating is damaged or discolored, painting over it may be the best option.[4]
