Check with carrier
Acrylic, lead and other water‑based paints, including arts and crafts paints and watercolour paints, are considered liquids. These items are permitted in carry‑on baggage only when the container is 100 mL (3.4 oz.) or smaller, and they are packed in your 1L resealable, transparent bag containing liquids, gels and sprays.
Larger quantities of paint, or paints with chemical additives, require air carrier approval when packed in checked baggage.
