Ask the PB and the plasterer how much CaCl he is going to add to the plaster mix, as they like to add too much to speed up curing. This can result in mottling/blotching of the color finish (and, of course, when this happens, they blame pool chemistry...... ie YOU)! It never hurts to let them know that you've done your homework on something as critical as this.
