Poor Drying

The paint film could not dry thoroughly after normal necessary time and requires an extra long drying period, or fails to cure thoroughly.

Common Cause

1. (1) Incorrect mixing ratio of 2K paint (too much or less of hardener) .

2. Unsuitable hardener.

3. The temperature could not reach requirement. Normally speaking, when the temperature is lower than 10℃, the drying process would be excessively slow.

4. Over-thickness of the paint film.

5. Poor weather condition and poor ventilation.

6. Insufficient, bad quality or wrong thinner.

7. Incorrect application method.

 Repair

(1) Increase the drying temperature to make the paint film dry thoroughly.

(2) If the paint film could not dry thoroughly even by increasing the temperature, sand or remove the paint, then re-spray.
