I have a 12 year old pool which is in great condition with the exception of about a dozen spots (some the size of a quarter, some up to the size of a pickle jar top) where the cement is starting to peek through the marcite top coating. Wear and tear over the years combined probably with areas where the contractor didn't quite get a good thick coat of marcite applied when originally done. I understand it would cost about $6K - $8K (pool size roughly 18x36 with 7' deep end) to have the marcite coating redone. It doesn't look bad enough for me to take that drastic of a step, and I do understand that a contractor (or me) could patch these spots with the water drained....but I'm wondering if there is some product out there that I can patch or cover somehow without draining the water.
Anybody know of some product or idea that would work?
