I own a winter home in AZ that has a swimming pool. The concrete around the pool has a skim coat and there are patches that have come up from the base of concrete, making it look like a mangy dog. I had a man come out and he told me just patching wouldn't look good. The estimate he gave me for doing the whole area with a skim coat was $2200. I can't afford that. Anyone out there have a solution? Are there any products that will allow me or my carpenter to do the job?
