KT102 Airbrush Retarder Thinner — 60ml

Compact Size · Thins & Retards Drying · Fights Tip Dry · Non-Toxic

✅ Why Use a Retarder Thinner?

🔹 Two jobs in one bottle — thins your paint AND slows drying time, giving you better flow and longer working time in a single additive

🔹 Fights tip dry — keeps paint flowing at the needle tip instead of drying on it mid-session, especially at fine nozzle sizes (0.2–0.3mm)

🔹 Smoother blends and glossier finishes — extended drying time means softer transitions and better levelling before the paint sets

🔹 Same formula as KT202, compact size — the full-strength retarder thinner in a 60ml bottle, ideal for travel kits or trying before buying the 210ml

🔹 Non-toxic and solvent-free — safe indoors, gentle on airbrush seals, no harsh smell

📋 Product Description

The KT102 is a 60ml bottle of Kaleido Colorworks' combined retarder and thinner — the same formulation as the larger 210ml KT202, in a compact format. It's the size that comes included in Kaleido's paint sets, and it works just as well bought separately.

Add a few drops to your paint mix when you need extended drying time — during precision blending, soft colour transitions, gloss finishes, or any time warm or dry conditions are causing your acrylics to dry too fast at the needle tip. It thins the paint simultaneously, so you're adjusting both consistency and drying speed with one product.

The 60ml size is practical for travel kits, workshop bags, and tournament setups where space is limited. It's also a low-commitment way to try the Kaleido retarder thinner before investing in the full 210ml bottle. A little goes a long way — just a few drops per cup load — so even 60ml lasts through many sessions.

🔄 60ml vs 210ml — Which Size?

💡 Because you only use a few drops at a time, 60ml actually lasts a surprisingly long time. But if you already know you love the retarder, the 210ml KT202 is better value.

💡 Pro Tips

🔹 Less is more — start with 1–2 drops per cup load. You can always add more, but too much retarder makes surfaces slow to dry, tacky, and prone to collecting dust.

🔹 Combine with KT201/KT101 Thinner — use the standard thinner for consistency, then add a drop or two of KT102 retarder when you need extended working time. Independent control over viscosity and drying speed.

🔹 Essential for gloss and metallic finishes — these show grain and texture more than matt coats. The retarder helps paint level and flow before it sets, giving a smoother result.

🔹 Adjust for your climate — in hot, dry conditions, lean on the retarder more. In cool, humid weather, you may not need it at all.

⚖️ Worth Knowing

▸ Water-based acrylics only — not designed for enamels, lacquers, or solvent-based paints.

▸ Too much will cause problems — over-retarded paint stays wet too long, attracts dust, and can have reduced adhesion and durability. Stick to a few drops and increase only if needed.

▸ Not always necessary — if you paint in a cool, humid environment and don't experience tip dry, the standard KT201/KT101 Thinner may be all you need.

▸ Same formula as KT202 — if you already have the 210ml bottle at home, this is the same product in a smaller package. Useful as a travel companion, but no need to buy both for the workbench.
