Humbrol Decalfix (125ml) AC7432

Humbrol Decalfix (AC7432) is an essential solution for ensuring your model decals adhere cleanly and accurately to painted surfaces. Supplied in a generous 125ml bottle, this decal setting solution softens transfers to allow them to conform to curved, textured, or recessed surfaces — delivering a more realistic and professional finish.

Designed to work with water-slide decals, Decalfix reduces the risk of silvering and air bubbles by improving surface contact between the decal film and model. It softens the decal slightly, allowing it to settle into panel lines, rivets, and surface detail with minimal effort. This is especially helpful for aircraft, military vehicles, and figures where accuracy and realism are key.

Simply apply Decalfix to the intended area before placing the decal, then use a soft brush to gently press the decal into place. Once positioned, a second application over the top helps set the decal and ensures it conforms perfectly to the surface. It dries clear, leaving no visible residue, and can be used with most paint types including acrylics and enamels.
