How soon to start watering shotcrete?

Don't worry about water pooling in the deep end whatever does not soak through will get pumped out before plaster. If it is going to be more than a couple of weeks before they plaster you can stop watering after what ever time they told you for cure usually 14 days, but if you do that be sure to wet very well again a couple of times the day before plaster or you can just keep watering it right up to plaster no matter how long the it takes.
 
Thanks, I am working from home today, will get it wet every couple hours. I did mist it last night about 10pm after reading on the ACI site about wetting it down as soon as you can walk on it. Said the 1st 36 hours is the most critical.
