Carbon fiber is a material that consists of extremely thin fibers of carbon. This material is often used in the construction of airplanes and vehicles due to its strength and lightweight, which makes carbon fiber an ideal material for many applications. You can find it in sports cars, sports equipment, aircraft, and even bicycles!
However, people often ask whether carbon fiber can be painted. So today we would like to investigate and figure out whether this durable and strong material can accept paint. Read this article to learn how well carbon fiber holds paint.
Also, we will tell you how you can paint this material and what to consider before you reach for a paintbrush. Finally, you will learn whether painting carbon fiber is needed at all.
Can You Paint Over Carbon Fiber?
The short answer is yes. You can paint over carbon fiber, and moreover, this can be done in a variety of ways. However, you need to keep in mind that this material is not metal, which means that it has different characteristics than its metallic counterpart.
As a result, the procedure of paint application will vary from the one used for metal surfaces.
When you paint over carbon fiber, make sure you keep the following in mind:
- Painted carbon fiber will look considerably different from other parts
- Carbon fiber absorbs paint fast
- If you spill water on it, all the paint will run off
Also, it is important to note that the carbon fibers are very sharp! So if you happen to come in contact with them by accident, they will most likely cut into your skin. This is why you should always wear protective gloves and gear to keep yourself safe from pesky carbon fibers!
As for the best way of paint application, we would suggest you paint your carbon fiber surface using a spray can or an airbrush. This method is more preferable because using rollers and brushes can be difficult due to the small thickness of the material.
What Can Be Challenging In Painting Carbon Fiber?
Those who decide to paint over carbon fiber often forget that they can face different challenges during this process. However, these challenges and complications depend on how well you are aware of the material and its characteristics. The more you know before you start painting it, the better you are prepared. As a result, the easier the whole process will be for you.
So what shall you be informed about in advance?
- Painting this material is time-consuming
- If the surface is not prepared properly, your paint won’t hold to it
- If you apply too many coats of paint one by one with no waiting time between them, the carbon fiber will become darker
- Too many coats of paint on carbon fiber may lead to transparency loss
- Be very careful when applying paint as it can damage the surface if applied excessively!
- Carbon fiber is often uneven so painting over it can be difficult, especially for beginners
Now you know that it is possible to paint over carbon fiber, which is a piece of good news for sure!
However, as you have learned, doing this successfully may appear to be somewhat tricky, especially if you are new to this kind of job. This is why we are going to tell you more about painting carbon fiber to help you understand the whole process better.
How to Paint Over Carbon Fiber?
As you already know, the optimal way of paint application for carbon fiber is using a sprayer. However, if you decide to paint over carbon fiber by hand, make sure to use a roller and/or a brush.
With their help, you will be able to cover the surface properly and besides, these tools will leave either little or no streaks on the surface. Finally, should you decide to use an airbrush, make sure you dilute your paint properly to get a smooth and even coating!
For painting carbon fiber, the following tools will be needed:
- Long sleeves
- Painter’s mask
- Painters tape
- Rollers and brushes or airbrush
Now let’s see how the process should go step by step. It will allow you to avoid the most common mistakes and make your job better.
Start With Thorough Preparation
The more thoroughly you are prepared for applying paint over carbon fiber, the better the results will be. So before you start painting, you need to make sure you clean the surface. You should use mild soap and water to wash it. Then, let the carbon fiber surface dry fully before you begin painting.
We also recommend you take a metal polish and rub it on the carbon fiber surface. It will not only give it a shine but also help the paint adhere to the surface better. When this part is done, proceed to the next one.
Apply Primer to Your Carbon Fiber Surface
After your carbon fiber surface is clean and properly prepared for paint application, don’t neglect to prime it! Primer is a must if you want a long-lasting appearance. It will help the surface to look even and make the paint to adhere to the surface better.
Proceed With Painting Your Carbon Fiber Surface
It is recommended that you start painting the carbon fiber surface using a light shade of paint. Like this, you will be able to tell where there is still paint and where it needs a few touch-ups. Also, make sure you apply the layers of paint carefully with no rush, letting each layer dry before you start applying another one.
Once your base layer is finished and fully dry, you can start adding details by applying darker shades. However, since this step is somewhat more delicate than applying the light shade of paint, we would recommend you try using an airbrush for the best results.
Don’t Forget to Polish It
After the first couple of coats of paint are applied to your carbon fiber surface, it can be polished with a rotary device. Polishing will help you ensure that paint adheres to the surface properly and doesn’t peel off easily.
Finish Your Carbon Fiber Paint Job
Once the whole painting process is finished, the paint should have enough time to dry, normally, for at least 24 hours. After that, apply a clear coat of sealant to protect it. For the best results, we would suggest you use the sealant that makes your paint look matte and very smooth.
Now you know exactly how to paint carbon fiber. You know what tools to use and how to apply paint correctly to avoid flaws and get an ideally smooth coating in the end. Now there is only one thing we need to discuss.
What to do if you need to remove paint from your carbon fiber?
How to Remove Paint From Carbon Fiber?

However, make sure you do it very carefully! For this purpose, fine sandpaper or a sanding machine can be used equally successfully. Just be careful not to overdo it, otherwise, you will ruin the material!
In comparison to the method described above, if your goal is to get rid of a new coat of paint from carbon fiber, you should make use of a pumice stone. It is very hard and will not damage the material if you use it correctly. The general rule of thumb says that you should rub in one direction only.
