How to Paint JoyCons: DIY Customization Guide

Transforming your Nintendo Switch Joy-Cons into a personalized statement piece is one of the most rewarding ways to customize your gaming setup. Whether you want to match your favorite game aesthetic, create a unique visual identity for online streams, or simply breathe new life into worn-out controllers, the process is both accessible and deeply creative. This guide walks you through every stage, from preparation to the final coat, ensuring your vibrant designs last through countless adventures.

Preparing Your Joy-Cons for a Flawless Finish

The foundation of a professional-looking paint job lies entirely in the preparation phase. Rushing this step guarantees peeling, streaks, or a grainy texture that undermines all your hard work. You are not just cleaning; you are creating a perfect, receptive surface for the paint to bond to.

• Disassembly is Key: Begin by carefully detaching the grip panels from the main body of each Joy-Con. Use a tri-wing screwdriver to remove the single screw located behind the rubber plug on the back. Gently pop the grips off using a spudger or guitar pick to avoid cracking the plastic.
• Deep Cleaning: Wash the separated components with warm, soapy water to remove oils from your hands. Once dry, use a plastic-safe cleaner or isopropyl alcohol (90% or higher) to wipe down the surfaces. This eliminates any remaining grease or factory mold release agents.
• Light Sanding: For glossy paint to adhere properly, the surface needs a slight tooth. Use 400 to 600-grit sandpaper to lightly scuff the finish. The goal is a matte, uniform texture, not to remove the color. Wipe away the dust with a tack cloth immediately after.

Masking and Protection

Before the first drop of color touches the plastic, you must protect the functional and aesthetic elements you do not want to paint. This includes the rubber buttons, the analog sticks, the speaker grilles, and the small engraving text on the back.

• Use high-quality painter's tape to cover the D-pad, face buttons, and the small mounting holes.
• Apply low-tack masking tape or liquid masking fluid over the analog stick shafts and the speaker mesh.
• Cover the small white indicator lights on the back with small pieces of tape to prevent paint from dulling the light diffusion.

Choosing Your Color Strategy and Materials

The market is flooded with spray paints and specialty coatings designed for plastics, but not all are created equal. Selecting the right products ensures your color looks vibrant and survives the wear and tear of regular use.

• For Solid Colors: Look for spray paints specifically formulated for plastic, such as Krylon Fusion or Rust-Oleum 2X. These brands bond aggressively without a primer.
• For Detailed Art: Airbrush enthusiasts should use urethane or acrylic paints mixed with a reducer for smooth flow. Detail brushes or small-scale airbrushes are essential for intricate patterns or logos.
• Essential Extras: Invest in a high-quality plastic primer (if your paint isn't multi-purpose), a Matte or Gloss clear coat for protection, and Citadel ‘Liquid Leaf’ if you want to paint metallic elements like the small rails.

The Painting Process

Applying the paint correctly is about patience and distance. Holding the can too close results in drips; spraying from too far away creates a dusty, uneven finish.

• The Test: Always test your spray on a scrap piece of plastic or a piece of cardboard first. This allows you to adjust the pressure and distance.
The Technique: Hold the can approximately 8 to 10 inches away. Apply thin, even coats using a side-to-side motion. Never attempt to cover the entire area in one thick coat; this leads to runs and sagging.
• The Layers: Wait 5 to 10 minutes between coats. Build up the color gradually over 3 to 4 layers until the underlying color is fully opaque.

Adding Decals and Custom Designs

Once the base color is locked in, you can move on to the artistic flourishes that make your controllers truly unique. This stage offers the most room for personal expression, whether you prefer sharp vector graphics or a painterly abstract style.

• Vinyl Cutting: If you possess a Cricut or Silhouette machine, cut your designs into adhesive vinyl. Carefully place the mask on the Joy-Con, smoothing out air bubbles with a credit card.
• Hand Painting: Print your design lightly with a pencil, then go over the lines with a fine brush. Use masking tape to create sharp, geometric lines by painting the edges first.
• Hydro Dipping (Optional): For complex patterns like camouflage or wood grain, a Dipping Film kit can transfer the pattern onto the plastic in a single dip. This method requires significant cleanup but offers unparalleled complexity.

Sealing Your Work and Reassembly

The final step is arguably the most critical. A beautiful paint job is useless if the paint scratches off the moment the controller drops. A durable clear coat locks in your work and returns the plastic to a smooth, tactile finish.

• Ensure the painted surface is completely dry—waiting an hour is a good rule of thumb.
• Apply 3 to 4 thin, even coats of a clear urethane or acrylic topcoat, allowing 15 minutes of drying time between applications.
• Hold the can at an angle to avoid dripping on the edges of the painted area.

After the clear coat has cured for at least 24 hours, it is time to put the controllers back together. Reverse the disassembly process by gently pressing the grip panels back into place and securing the rear screw. Power on your Switch and enjoy the satisfaction of using equipment that looks as good as it performs.
