You might be wondering how to spray paint your pc case. You might also be put off and think it’s too hard, but I’m here to show you – it’s easy.

What do I need to spray my pc case?

Good question; Over here in the UK, these supplies cost me £30 ($50USD). A lot less than a new PC case! If you are spraying a brand new PC you can likely get away with not using a primer.

Step One: Remove Old Components

I’m pretty sure that if we don’t remove the components, we might have a few issues, don’t you? Let’s get the components out of the case ready for preparation.

Step Two: Prepare the case for Spraying

Before we can spray the case, you need to remove any dust, particles and surface contaminants before moving on. Here is my checklist for cleaning up my client’s cases.

  1. Get an old sock, place it over the end of the Hoover pipe and clear out any big dust balls are particles
  2. Grab a lint-free, microfibre cloth and give the case a quick wipe around
  3. Give the same cloth a bang to remove any dust, and apply some ISOPRYL to the clothe
  4. Clean the entire case with the isopropyl and cloth. It will remove old dirt and contaminants.

Step Three: Lightly sand the surfaces

Even if you have a brand new case, it is always wise to give things a light sanding. You want a really fine grit, nothing that will leave big gauges in the metal. Instead, they will prepare the surface so that the primer and spray paint will properly bond with the metal.

You can choose to skip this step, but in my personal experience, the result is worth the extra effort to sand your PC case.

Step Four: Lay down thin coats of filling primer

To get a really smooth finish, a couple of thin layers of filling primer will create a lovely smooth surface for the spray paint to finish too. Don’t apply thick coats; three thin coats are better than one thicker coating.

Step Five: Spray the case

Just like the previous step, thinner spray paint coats will result in a smoother finish. It will also cure faster, which will let you get the job done faster.

Pro tip: If you want an ultra glossy finish, get some wet and dry sandpaper and give it a light rub between each coat.

Step Six: Put the case back together

Get the case put back together, but don’t forget to let the spray paint adequately cure; otherwise, you will end up with your paint peeling, sticking and other things you don’t want on your freshly spray-painted pc case.
