Do I need both setting solution and softener?

Setting solution (like Micro Set) helps the decal adhere and reduces silvering. Softener (like Micro Sol) melts the decal film to conform to surface detail. For flat surfaces, setting solution alone may suffice. For riveted or complex surfaces, use both.

Should I apply gloss coat before decals?

Yes, always. Decals applied to a matte surface will silver badly. Apply a gloss coat, let it cure 24 hours, then apply decals. After decals are dry, seal with another gloss coat, then apply your final matte or satin finish.

How long should I soak decals?

Small decals: 10-15 seconds. Medium: 15-25 seconds. Large: 30-60 seconds. The decal should slide freely on the backing paper but not float off. Over-soaking dissolves the adhesive. Use warm (not hot) water.

How do I avoid silvering?

Silvering is caused by air trapped under the decal film. To prevent it: apply over a gloss surface, use setting solution, prick any air bubbles with a pin, and apply softener to melt the film down onto the surface. Work from the centre outward.

How We Calculate This

Estimates setting solution and softener quantities based on decal count, size and surface complexity.

Formula

Setting solution = Decal count x 0.1ml x Size factor x Complexity factor
Softener = Setting solution x 0.6
Gloss coat = Decal count x 0.3ml x Size factor (if matte surface)
