| Ray , thats almost exactly what I did on both of my plaster ponds as well as a newley plastered hot tub. I have found that size makes a difference. The hot tub cured in two weeks , the smaller pond in about four and the 8,000 gal pond in about six. You'll need to shop around for the least expensive muratyic acid you can find because if you are doing anything of any size you are gonna need dozens of gallons. The best I've found if Lowes so far.
