I am looking at resurfacing options for my 30 year old peagravel pool deck. I have heard about a resurfacing product called Carvestone and another one called Limecoat. I believe they are similar to each other. They are supposed to be longer lasting than sundeck and it is said to be harder than concrete. Does anyone have any experience with either one of these products? I cannot find any consumer reviews about them, only websites from the companies who make or apply them. I have sundeck in another location and I decided that I do not want to use that from my pool deck. I live near Houston.
