Dry times and curing times?

Drying is 3-5 hours per coat , curing time after the final coat. before you fill with water is 5-7 days. 

If you apply new coats after the coating has cured you must follow  the same process as above.

To test if it is cured. After five days sprinkle some water on the coating if it turns light in color it is not fully cured if it stays the same you are good to fill.
