Humbrol Decalfix (28ml) AC6134

Humbrol Decalfix (AC6134) is a precision decal setting solution supplied in a 28ml glass bottle, specially formulated to improve decal adhesion and finish. Designed for water-slide decals used in scale modelling, Decalfix softens the decal film, allowing it to conform to complex surfaces, panel lines, and raised details — ensuring a clean, professional result every time.

Decals applied over untreated surfaces often suffer from issues like silvering, poor adhesion, or trapped air. Humbrol Decalfix addresses these challenges by preparing the surface and helping the decal settle into the model’s texture. It enhances realism, giving decals a painted-on appearance rather than the look of a separate layer.

To use, simply brush a thin coat of Decalfix onto the area where the decal will be applied. Place the wet decal onto the surface and gently adjust its position. Apply another light layer over the top to help the decal conform fully. The solution works on painted surfaces finished in gloss, satin, or matt, though a gloss base is typically recommended to prevent silvering.

It is safe for use on both enamel and acrylic finishes, and dries without leaving residue or clouding. For best results, allow decals to dry thoroughly before applying a protective varnish.
