Applying decals is one of the most satisfying yet nerve-wracking steps in model building. A perfectly painted kit can be ruined by a decal that silveres—those unsightly silver edges that appear when air gets trapped under the decal film. But with the right technique and a few essential products, you can achieve smooth, painted-on decals every time.
In this guide, we'll walk through the entire process of applying water slide decals, from surface preparation to final sealing. We'll also cover common mistakes and how to fix silvering if it happens. Whether you're working on a 1/80 scale super minifigure or a detailed military kit, these tips will help you get flawless results.
Why Decals Silver and How to Prevent It
Silvering occurs when the clear carrier film of a decal doesn't fully adhere to the model surface, leaving tiny air pockets that reflect light and appear as silver or white edges. This is most common on rough or matte surfaces, or when the decal isn't pressed down firmly enough. The key to preventing silvering is to ensure a smooth, glossy surface and to use the right application technique.
Start by applying a gloss clear coat to the area where the decal will be placed. A glossy surface provides a smooth, non-porous base that allows the decal to adhere evenly. If you're working on a matte paint finish, consider using a gloss varnish before decaling. This step is especially important for scale model kits with intricate details.
- Always apply decals over a glossy surface to minimize silvering.
- Use a soft brush or cotton swab to press out air bubbles and excess water.
- Consider using a decal setting solution for stubborn decals.
Essential Tools and Materials for Decal Application
Before you start, gather the right tools. You'll need a sharp hobby knife or scissors, a pair of tweezers, a small bowl of warm water, a soft brush or cotton swab, and a paper towel. A decal setting solution can be a game-changer—it softens the decal and helps it conform to curved surfaces. A decal softer is also useful for tricky areas.
For cleaning and preparing the surface, a cotton swab dipped in mild soapy water can remove any dust or oils. If you're working on a kit like the 1/80 Scale super minifigure series8 Expert Office Worker Set 2, precision is key, so having fine-tipped tweezers is essential.

- Use warm water, not hot, to activate the decal adhesive.
- Keep a damp paper towel handy to remove excess water.
- Invest in a quality decal setting solution for best results.
Step-by-Step: Applying Water Slide Decals Smoothly
First, cut out the decal you want to apply, leaving a small margin around the design. Dip it in warm water for about 10-20 seconds until it starts to slide off the backing paper. Slide it onto the model surface using a damp brush or tweezers. Position it carefully, then press out any air bubbles with a soft brush or cotton swab, working from the center outward.
Once the decal is in place, apply a decal setting solution if needed. This helps the decal soften and conform to contours. After it dries, you can apply a second coat if necessary. Finally, seal the decal with a clear coat to protect it and blend it into the surrounding paint. This step is crucial for a professional finish.
- Work quickly but carefully—don't let the decal dry before positioning.
- Use a setting solution like Mark Fit or Micro Sol for curved surfaces.
- Allow the decal to dry completely before applying a clear coat.
Fixing Decal Silvering After It Happens
If you notice silvering after the decal has dried, don't panic. There are ways to fix it. One method is to carefully prick the silvered area with a sharp needle and apply a small amount of decal setting solution to seep under the film. Press the decal down with a cotton swab and allow it to dry.
Another technique is to apply a thin layer of clear varnish over the decal and let it dry. This can sometimes hide the silvering. For severe cases, you may need to remove the decal entirely and start over. To avoid this, always ensure your surface is glossy and your decal is fully adhered before sealing.
- Use a needle to let setting solution seep under the decal.
- Apply a clear coat to help hide minor silvering.
- If all else fails, remove the decal with tape and reapply.
Advanced Tips for Perfect Decals on Curved Surfaces
Curved surfaces are the most challenging for decals. To make a decal conform to a curve, use a decal softener that melts the film enough to stretch. Apply the softener after positioning the decal, then gently press it into place. Be careful not to overdo it, as too much softener can cause the decal to tear.
For complex shapes, you can also cut the decal into smaller pieces and apply them separately. This is particularly useful for panel lines and raised details. Practice on a scrap piece first if you're new to this technique.
- Apply decal softener in thin coats to avoid damaging the decal.
- Use a hairdryer on low heat to help the decal conform to curves.
- Patience is key—work slowly and carefully.
With these techniques, you can apply decals like a pro and avoid the dreaded silvering. Remember to prepare your surface with a gloss coat, use quality setting solutions, and seal your work after. For your next project, consider adding a decal setting solution and a soft brush to your toolkit—they make a world of difference. Happy building!
