Glad to have joined this blog. We just got our pool resurfaced in Orlando and they used Marquis by Marbletite aggregate. Has been over a month and there are a few white streaks left after brushing it for the past 30 days about 2-3 times weekly. After several chemical balances and after the 30 days it now has little plaster dust left but the pale white streaks are still there. That is why I entered this site - To see some pics of someone else who had this. Our pool resurfacer did admit that he used some extra calcium to accelerate the concrete hardening and I hope we don't have frank mottling or white spots next year!
