What kind of paint do you use on keycaps?

When it comes to painting keycaps, it’s important to use the right type of paint that adheres well to the keycap material and provides a durable and long-lasting finish.

Here are some commonly used paints for keycap customization:

Acrylic Paint:

Acrylic paint is a popular choice for painting keycaps. It is readily available, comes in a wide range of colors, and adheres well to various keycap materials such as ABS or PBT.

Acrylic paint dries relatively quickly and can be easily applied with brushes or airbrushes. It’s important to note that acrylic paint may require a sealant or top coat to protect the painted surface.

Enamel Paint:

Enamel paint is another suitable option for keycap painting. It provides a smooth and glossy finish and has good durability. Enamel paint takes longer to dry compared to acrylic paint and may require multiple coats for full coverage.

And Also, it’s essential to work in a well-ventilated area when using enamel paint due to its strong odor.

Spray Paint:

Spray paint can be used for keycap customization, particularly for covering larger areas or achieving even coatings. It’s important to choose spray paint specifically designed for the intended keycap material, such as plastic or metal.

Ensure that you follow the manufacturer’s instructions, use appropriate primers if required, and apply the spray paint in thin, even layers for best results.

Keycap-specific Paints:

Some companies offer keycap-specific paints formulated specifically for keycap customization. These paints are designed to adhere well to keycap materials, provide vibrant colors, and offer good durability.

They may come in brush-on or airbrush-friendly formulations. These specialized paints can be a convenient choice if you prefer a hassle-free painting experience.

Keep in mind That!

  • Use a light touch. You don’t need to apply a lot of paint to get a good coverage.
  • Apply multiple coats. This will help to create a smooth and even finish.
  • Let the paint dry completely. This is important to prevent the paint from chipping or peeling.
  • Seal the paint with a clear coat. This will help to protect the paint from fading and chipping.

Once you have chosen a paint, it is important to prepare the keycaps before painting. This includes cleaning the keycaps with soap and water and sanding them with a fine-grit sandpaper. This will help the paint to adhere to the keycaps and create a smooth finish.

After the keycaps have been prepared, you can apply the paint. It is important to apply the paint in thin coats and allow each coat to dry completely before applying the next coat. This will help to prevent the paint from bubbling or cracking.
