Can You Paint Carbon Fiber? Easy Way!

Since carbon fiber is a very delicate and smooth material, it is sometimes difficult to determine whether it can be painted. 

You can paint a carbon fiber, but remember that painting a carbon fiber differs from painting a normal material. This is because the woven material tends to absorb the paint very quickly.

No worries if you find it still confusing. I have shared a detailed guide about how to paint carbon fiber. Surely at the end of this guide, you’ll be all clear about the facts related to the painting carbon fiber.

So let’s get started.

Can You Paint Carbon Fiber?

Yes. But painting a carbon fiber is different from other materials because the material is woven together and absorbs more quickly than normal paints.

Also, carbon fiber is a very delicate and smooth material, so you’ll need to take high care while painting it. 

Additionally, there are specific paints that are ideal for carbon fiber. So, it is highly recommended that you should use those paints. 

What Type Of Paint Can Be Used On Carbon Fiber?

Carbon fiber can be painted with paints, including enamels, acrylics, and lacquers. A urethane-based paint designed specifically for automotive applications will provide the best finish and durability.

Things To Consider Before Painting The Carbon Fiber

The following things must be considered before painting the carbon fiber:

  • Always look considerably different from other parts
  • Don’t spill the water over the paint.
  • Keep patience because painting a carbon fiber needs attention to detail.
  • Don’t use any normal paint. Go with the specific paint made for the carbon fiber.
  • Always prepare the surface by lightly sanding it and then use a primer for the carbon fiber surface.
  • You have to work in small sections quickly because the paint will get absorbed quickly.
  • Remember, the paint will add weight to the carbon fiber part. So always consider this factor before painting.

How To Paint Carbon Fiber: Step-By-Step Guide

Before going towards the procedure, you need these materials:

Materials Required

  • Carbon Fiber part
  • Sandpaper (At Least 600 grit or higher)
  • Masking tape
  • Primer
  • Paint
  • Clear Coat

Follow this step-by-step guide to painting carbon fiber:

Step 1: Clean And Sand The Surface

The first and foremost step of painting a carbon fiber is cleaning the surface using mild soap and water.

After the cleaning, sand the surface of the carbon fiber; this helps the paint adhere better. For sanding, sand the fine-grit sandpaper in a circular motion.

This is because carbon fiber is very smooth, so sanding it properly before painting will give the primer paint something to grip onto.

Just create an evenly sanded rough surface with the sandpaper. It is not important to sand down to the bare carbon fiber.

Although if there is already an old layer of paint, make sure to remove that layer properly, as it will create a problem with the adhesion.

Step 2: Apply Masking Taps

Now in the second step, you have to apply the masking tapes to any area you don’t want to be painted.

You can use the 3M Scotch-Blue multi-surface medium adhesion tape ideal for painted trims, walls, glass, metal, and plastic.

Step 3: Apply A Primer

After sanding and covering the other parts with the masking tape, apply a primer made specifically for the carbon fiber.

Primer will help the paint adhere to the surface and create a smooth and shiny finish. 

Rust-Oleum Brush on Automotive Filler Primer is an ideal product on surfaces including metal, wood, carbon fiber, etc.

You can buy this primer here.

Step 4: Let The Primer Dry

After applying the primer, let it dry completely. It’s an important step because it will help prevent the paint from peeling or chipping over time.

So make sure you allow the primer to dry completely before applying the paint.

Step 5: Apply The Paint To Carbon Fiber

Once the primer is dry, you can start painting the carbon fiber.

The best way to paint a carbon fiber quickly is with a spray can or an airbrush because brushing and rolling it can be tricky due to its thickness.

But if you don’t have an airbrush or spray can then use a bristle paintbrush or a small nap roller, and always start with the small sections. Also, work quickly as the paint will absorb fast.

It is recommended that you should consider applying the lighter base shade first and then the darker shade. This will let you achieve a more consistent and detailed finish.

Step 6: Let The Paint Dry And Apply A Clear Coat

After applying the paint to the carbon fiber, let it dry for several hours. After that, apply a clear coat to protect the paint and achieve a detailed and shiny finish.

Applying a clear coat is unnecessary, but I would recommend it as it protects the paint and gives a shiny look to the carbon fiber.

If you are confused about choosing the best Clearcoat, I recommend using a Flitz Multi-purpose sealant product to give your paint a matte finish.

Along with its shine, it also protects your carbon fiber from UV rays.

For the extreme gloss mirror finish, you can also use the SprayMax 2K Glamor High Gloss Aerosol Clear.

Start applying the clear coat with the small sections and work quickly because the coat will absorb quickly. 

Step 7: Let The Paint Dry For 24 Hours

After applying the clear coat, the next step is to cure the paint. Let it dry for about 24 hours before you wash the carbon fiber. 

This helps to ensure that the paint adheres properly and does not chip or peel over time.

5 Mistakes To Avoid While Painting Carbon Fiber

1- Not Using Enough Primer

This is the most common and big mistake. Remember, if you skip priming, you risk peeling paint, especially in humid conditions. 

Applying too little primer will result in the paint not bonding properly to the carbon fiber surface. This can cause peeling and flaking after a few times.

If you don’t correctly apply the primer, it could also make cleaning more difficult for you after a few months. Additionally, you may also find the paint cracking and wearing off.

2- Using The Wrong Primer

It is also a big mistake that people make. They use a normal primer instead of a high-quality one made specifically for carbon fiber.

I recommend using the Rust-Oleum brush primer on the carbon fiber surface. You can buy from here:

2- Not Sanding The Carbon Fiber Before Painting

According to the research, if you don’t sand the carbon fiber surface before painting, the applied paint could peel off. 

Sanding the surface will help create a smooth base for the paint to adhere to.

3- Applying Too-Thick Paint

Applying too thick paint can cause ridges, lumpiness, or an orange peel finish. Thick paint can cause runs and sag.

So, always apply the thin coats and allow each coat to dry before applying the other coats.

4- Failing To Clear Coat

A clear coat provides your paint with a detailed and shiny finish. It also ensures a long-lasting shine and life to your paint. So, always make sure to apply the clear coat after painting.

5- Not Drying The Paint

Lastly, most people don’t let the paint dry and wash the carbon fiber surface before drying. Remember, this act will ruin all your hard work. So, make sure to dry the surface before washing and waxing.

Bonus Tips For Painting Carbon Fiber

  1. Always use a primer specifically designed for the carbon fiber. 
  2. Never use thick paint layers. Always use thin layers of paint to avoid sagging and running.
  3. Apply a clear coat after painting to protect the paint job and give it a shiny finish.

How To Remove Paint From Carbon Fiber?

There are a few methods to get paint off carbon fiber, but the best and most effective way is to use a solvent-based paint stripper.

Follow these steps to get this done:

  1. Apply the stripper to the part of carbon fiber with the sprayer or brush.
  2. Leave it for some time.
  3. Afterward, you can use a putty knife or other sharp object to scrape the paint.

Why Does Carbon Fiber Look Old: Can It Be Repaired?

Like metal and other paints, carbon oxidizes if not taken care of properly. The process slowly wears away at the outside surface of the carbon piece.

If this damage is left unchecked, it will cause the shiny finish on the carbon fiber to fade and look dull and old.
