Ral 5018 Turquoise Blue

RAL 5018 Turquoise Blue: Fresh turquoise blue with a green lean

RAL 5018 Turquoise Blue is a fresh, clear blue-green with a lively character. It is used on facades, signage, pool and leisure equipment, and design products. For modelers it is a fun colour for retro civilian cars, scooters, campers and boats, and for signs and seaside details in dioramas. It suits 1950s and 1960s inspired custom builds particularly well. A white primer keeps it bright and clean, avoiding a dull, greyish tone.

Getting the tone right

Blues, greens and purples change character with the primer underneath and the number of coats. Build the colour in light, even passes over the recommended primer and you get the same tone on every panel.

How to apply

1. Shake the bottle for at least 60 seconds.
2. Prime with a white primer and let it dry fully.
3. Airbrush straight from the bottle, no thinning needed. Use a 0.2–0.4 mm nozzle at around 20 PSI (1.4 bar) and apply light, cross-hatched coats, letting each one flash off before the next.
4. Let the paint cure overnight before masking or clear-coating.
5. Seal with a water-based clear coat: gloss for a factory shine, or satin or matte for work vehicles and interiors.
6. Clean the airbrush with water before the paint dries.

Why modelers choose Koloi Aqua

• Ready to spray: no guessing thinning ratios, the same result from every bottle
• Cleans up with water, so there are no strong solvent fumes at the bench
• Fine pigment grind for 1:8 to 1:72 scales, so panel lines and detail stay crisp
• One system: primer, colour and clear designed to work together

Shelf life

Estimated shelf life of more than 12 months when stored tightly closed between +10 °C and +28 °C, away from frost and direct sunlight. Shake well before use; if the paint has thickened or separated and does not remix, do not use it.
