Learn how to apply large flag transfers to wargame banners with a step-by-step process, common mistakes to avoid, and practical tips for 28mm miniatures.
Quick answer
Applying large flag transfers to wargame banners requires careful surface prep, controlled water temperature, and a steady hand to avoid wrinkles and air bubbles. The key is to match the transfer diameter to your shield size, especially when using mixed-size castings.
Why Transfer Size Matters for Mixed Shield Castings
Many 28mm figure packs include shields of varying diameters cast directly onto the models. For example, Gripping Beast extra large round shield packs LR17, LR18, and LR19 contain shield sizes ranging from 14mm to 17mm. A single transfer sheet that covers an average diameter (14mm, 15mm, 16mm) works for most shields, but you may need to trim or center the decal carefully on the largest or smallest shields.
The shield boss diameter is consistent across these models (4mm), so you can align the transfer using the boss as a reference point. This reduces the risk of off-center placement on irregularly shaped castings.
Surface Preparation for Decal Adhesion
A smooth, clean surface is essential for large transfers to lie flat. Apply a base coat and at least one layer of gloss varnish to the shield area before adding the transfer. The gloss creates a slick surface that allows the decal to slide into position without tearing.
Avoid matte or satin finishes under the decal; they create friction that can cause the transfer to crinkle or adhere prematurely.
Step-by-step transfer application
- 1. Prepare the surface: Apply a base coat and a layer of gloss varnish to the shield area. Let it dry completely. This creates a smooth, non-porous surface that helps the decal slide and reduces air bubbles. Skipping the gloss varnish is the most common cause of decal tearing during positioning.
- 2. Cut and soak the transfer: Cut out the desired transfer close to the edge. Soak it in room-temperature water for 20–30 seconds until the decal loosens from the backing paper. Do not oversoak; the decal becomes fragile and may fold onto itself. Use cool or lukewarm water—hot water can distort the decal film.
- 3. Slide and position: Slide the decal onto the shield using a damp brush or tweezers. Align it using the shield boss as a reference point. For shields smaller than the transfer, trim the excess with a sharp hobby knife before soaking. Work quickly but gently; the decal sets within 10–15 seconds once it contacts the surface.
- 4. Remove air and moisture: Gently roll a damp cotton swab from the center outward to push out air bubbles and excess water. Do not press hard or rub sideways, as this can tear the decal. A single trapped air bubble is easier to pop with a pin than to try to push out after the decal has set.
- 5. Seal the decal: Once the decal is fully dry (at least 30 minutes), apply a coat of gloss varnish to protect it. Follow with a matte or satin varnish to match the rest of the miniature's finish. Sealing with gloss first prevents the decal from silvering (appearing cloudy) under a matte topcoat.
