Zoo Med Excavator Clay typically takes 24 to 48 hours to fully dry, depending on thickness, humidity, and airflow, before it becomes firm and safe for reptile habitats.
It usually takes about 2 to 3 days for Zoo Med Excavator Clay to dry fully. If you used a lot of water or made the layers very thick, it can definitely take 76 hours or even longer. Using a fan or a heat lamp can help speed things up if it's taking too long.
