Why do you want to wait longer(which will make drier) yet you want to keep it wet?
watering it will help it cure slower, hopefully limiting the amount of cracking prior to the Color coat. But there would be no reason to wait more than 10 days.

We are actually using a new product on our homes that can be smooth/color coated immediately after scratch and Brown. So far it's worked very well.
