Answer: When resurfacing is an option would be when you see your concrete start to get worse and worse each year. If you have a little bit of pitting one year, and the next year it’s double and the next year it’s triple, it’s going to continually deteriorate even more. If you see year-to-year that it continually gets worse, that’s when you want to try and step in and put something to protect it, so it lasts longer.
