Hello everyone. Our concrete patio is in great need of resurfacing. Years of wear and tear is now too visible to ignore. We have several patches that need to be filled before we can apply an even surface. There are cracks and joints that possibly need to be filled with an expander of sorts given the freeze and thaw condition of Wisconsin. I looked around a bit and found some granite stone application that may work. Found another one called Cool Pool that is supposed to keep cool. I would like to ask what have you used before that was effective. We plan on doing the job ourselves, as we have other house projects that need to be hire out. Thank you much. Stay safe and healthy.
