There is the possibility if you are experiencing difficulty with the time needed for the paint to dry, that too much paint has been applied. If this is the case, the dry time may take longer than overnight. Due to heat and humidity, dry times may vary as well.

Painting directly on the ornaments is not recommended as the wet paint will drip and run.
