How to Apply Waterslide Decals Without Silvering: A Step-by-Step Tutorial

Quick Answer

To prevent silvering, ensure the surface is glossy and smooth, apply a setting solution before placing the decal, and use a softener to help it conform. Always remove excess water and air bubbles with a cotton swab. Practice on a spare part if you're new to waterslide decals.

Waterslide decals can transform a model kit from plain to professional, but nothing ruins that look faster than silvering—those cloudy, reflective patches under the decal. Silvering happens when air gets trapped between the decal and the surface, so the key is to eliminate any air and ensure perfect adhesion.

In this tutorial, you'll learn a step-by-step method to apply waterslide decals without silvering. We'll cover surface preparation, the role of setting solutions and softeners, and common mistakes to avoid. Whether you're working on a Gundam or any other model, these techniques will give you a clean, painted-on look.

Why Silvering Happens and How to Prevent It

Silvering occurs when the decal film doesn't fully adhere to the model surface, leaving tiny air pockets that reflect light. This is often caused by applying decals over a rough or matte surface, or by not using enough setting solution. The fix is to start with a glossy finish.

A gloss coat (like a clear gloss varnish) creates a smooth, shiny surface that the decal can bond to. If you've already painted your kit with a matte finish, apply a gloss coat over the area where you'll place decals. This one step dramatically reduces the risk of silvering.

• Always apply decals over a gloss coat for best results.
• If you must use a matte surface, use a decal setting solution to help the film adhere.

Gathering Your Tools and Materials

Before you start, gather everything you'll need: a shallow dish of warm water, a pair of tweezers, a cotton swab or soft brush, a hobby knife, and a decal setting solution (like Mark Setter) and a decal softener (like Mark Softer). These solutions are specifically designed to help decals stick and conform to curved surfaces.

For Gundam kits, high-quality waterslide decals like those from G-Rework are a great choice. They are thin and designed to sit flat, which reduces silvering. You can find them for specific kits, such as the G-Rework Decal for the RG Shining Gundam or the RG Gundam Exia.

• Use warm (not hot) water to loosen the decal from its backing paper.
• Have a clean, dry cloth nearby to blot excess water.

Step-by-Step Application Process

Start by cutting out the decal you want to apply, leaving a small margin around it. Dip it in warm water for about 10-15 seconds, or until the decal slides easily on its backing. Slide the decal onto the model using a wet brush or your fingertip, positioning it carefully.

Once the decal is in place, use a cotton swab to gently roll out any air bubbles and excess water from the center to the edges. If you're working on a curved surface, apply a decal softener to help the film conform. Let it dry completely before applying a topcoat.

• Work quickly but carefully; decals can tear if they dry out.
• Don't press too hard with the swab, or you might damage the decal.

Step-by-Step: Apply Waterslide Decals Without Silvering

1. Prepare the surface: Apply a gloss coat to the area where you'll place decals. Ensure it's completely dry and smooth. A glossy surface is the foundation for preventing silvering.
2. Cut out the decal: Use a sharp hobby knife to cut close to the decal design, leaving a thin border. Clean edges reduce the chance of the film lifting.
3. Soak in warm water: Dip the decal in warm water for 10-15 seconds until it slides freely on the backing paper. Don't soak too long or the decal may detach and curl.
4. Apply setting solution: Brush a thin layer of setting solution (like Mark Setter) on the model where the decal will go. This helps the decal adhere and reduces air pockets.
5. Position the decal: Slide the decal onto the model using a wet brush or tweezers. Adjust it while it's still wet. Work quickly; the decal sets as it dries.
6. Remove air and excess water: Roll a cotton swab from the center outward to push out air bubbles and water. If bubbles remain, lift the decal edge and re-roll.
7. Use softener for curves: Apply decal softener (like Mark Softer) to help the decal conform to curved or detailed surfaces. Don't overdo it; softener can weaken the decal if used excessively.
