Mastering the Art: A Guide to Applying Decals on Plastic Models - Access Models

For enthusiasts of plastic modelling, the application of decals is a crucial step in bringing a model to life. Whether you’re a seasoned hobbyist or a beginner, understanding the art of decal application is essential to achieving a professional and realistic finish on your models. In this guide, we’ll explore the world of decals, providing tips and techniques to master this delicate process.

What are Decals?

Decals are graphic images printed on a special paper, designed to be transferred onto another surface - in this case, plastic models. They range from simple designs like numbers and letters to intricate patterns and emblems. These decals are vital for adding detail and authenticity to your model, whether it’s a historical aircraft, a fantasy figurine, or a scale model of a vehicle.

Types of Decals

  1. Water-Slide Decals: These are the most common type of decals used in plastic modelling. They require water to activate the adhesive and are known for their thinness and flexibility.
  2. Dry Transfers: These decals don’t need water and are rubbed onto the model’s surface. They are less common but useful for specific applications.
  3. Sticker Decals: These are essentially peel-and-stick and are easier to use but can be thicker and less realistic in appearance.

Preparing the Surface

Before applying decals, it’s crucial to ensure the surface of your model is prepared. A smooth, clean surface is key. Wash the model to remove any grease or dust and consider applying a gloss coat. The gloss coat provides a smooth surface for the decals to adhere to, reducing the chance of 'silvering' – trapped air bubbles that can spoil the appearance.

Tools and Materials

  • Decals
  • Warm water
  • Tweezers
  • Soft brushes
  • Decal solutions (setting and softening)
  • Microfiber cloth
  • Gloss and matte clear coats

Applying Water-Slide Decals

  1. Cutting Out the Decal: Trim closely around the decal with a sharp blade or scissors.
  2. Soaking: Immerse the decal in warm water for a few seconds until it starts to loosen from the backing paper.
  3. Placement: Slide the decal onto the model’s surface, using tweezers and a soft brush for positioning.
  4. Setting Solution: Apply a decal setting solution to help it conform to the model's contours. Be gentle to avoid tearing the decal.
  5. Drying: Allow the decal to dry completely. Avoid touching it during this stage.

Post-Application Finishing

Once the decals are applied and dried, it’s important to seal them with a clear coat. This not only protects the decals but also integrates them into the overall finish of the model. A matte or satin clear coat is often preferred to give a more realistic appearance.

Troubleshooting

  • Silvering: This is usually caused by air trapped under the decal. Use a pin to prick tiny holes and apply more setting solution.
  • Tearing: If a decal tears, try to realign it gently with a wet brush and apply softening solution.

Conclusion

Applying decals is a skill that enhances the realism and detail of your plastic models. With practice, patience, and the right techniques, you can master this art and take your modelling projects to the next level. Remember, each model is an opportunity to refine your skills and express your creativity. Happy modelling!
