KT102: the Kaleido retarder that gives control back to your airbrush

Working with an airbrush in dry climates or during long sessions has a silent enemy: paint that dries prematurely on the needle. The KT102 Airbrush Retarder from Kaleido acts directly on solvent evaporation, extending the open time without altering the colour or adhesion of the paint. The result is a smoother, more controlled application that is much less frustrating.

What the KT102 brings to your painting technique

Adding a few drops of KT102 to the paint mixture produces noticeable changes from the first pass:

  • Eliminates tip dry: paint stops solidifying on the needle during short pauses or angle changes, reducing interruptions and mid-session clean-ups.
  • Better leveling: the rough or orange peel appearance disappears. The layer settles more evenly on the surface.
  • Smoother fades and glazes: by extending working time, colour transitions become smoother and it is easier to build thin, controlled layers.
  • Constant flow at low pressures: particularly useful when working with reduced pressures for fine details in static models, figures, or dioramas.

Compatibility and recommended use

The KT102 is formulated for acrylic paints, the most common type in modelling and miniature decoration. Its technical composition does not alter the chromatic properties or adhesion of the base paint, making it suitable for use with Kaleido and other brands of acrylics in the industry.

The correct dosage depends on environmental conditions and the paint used. As a general rule, just a few drops per airbrush load are sufficient: adding too much can prolong drying time between layers excessively and hinder control of the final finish.

Applications: what types of projects is it most useful for?

  • Static models: large panels where the orange peel effect is particularly visible.
  • Figures and miniatures: zenithal highlights, shading, and glazes that require extra working time.
  • Dioramas: textured surfaces where uniform leveling makes a difference.
  • Sessions in dry or hot climates: when natural evaporation is too fast for wet-on-wet techniques.

Application tips

  1. Shake the paint well before preparing the mixture.
  2. Add the retarder drop by drop until the desired consistency is reached; do not mix too much at once.
  3. Conduct a test on a scrap surface before applying to the final piece.
  4. In very humid environments, reduce the amount of retarder to avoid excessive drying times.
  5. Clean the airbrush as usual after the session; the retarder leaves no special residues.

Frequently asked questions

How many drops should I add per airbrush load?

There is no universal amount, as it depends on the climate, paint, and technique. A good starting point is 1-2 drops per small load. From there, adjust according to the result observed in the test.

Does the KT102 affect the final colour of the paint?

No. Its technical formulation is designed to prolong evaporation time without altering the chromatic properties or opacity of the paint.

Is it compatible with any acrylic paint?

It is formulated for acrylic paints in general. If you are using different brands from Kaleido, always conduct a preliminary test to verify compatibility before applying to final pieces.

Can I also use it for brush painting?

The product is optimised for airbrush use, but it can be used with a brush in wet-on-wet techniques, where extended working time is also an advantage.

Does the KT102 change the drying time between layers?

Yes, it prolongs it. Therefore, it is important to dose wisely: in the right amount, it improves leveling; in excess, it can delay drying too much and hinder layering.

Is the 60 ml format sufficient for prolonged use?

Since it is used in small amounts per session, a 60 ml bottle has a long lifespan even for modellers who frequently use an airbrush.

The Kaleido KT102 airbrush retarder (60 ml) is a technical additive designed to extend paint open time, prevent tip dry, and improve leveling when airbrushing acrylic paints. Ideal for scale modelers, miniature painters and diorama builders who need smooth gradients and flawless finishes.
