I have used Ultimate Concrete Coatings a couple different times in the past few years. I was very happy with the first job, and I am relatively happy with the second job. I would say I am relatively happy with them overall. They showed up on time, and they did the work when they said they would do it. The first time they came out and coated my regular car garage, and it has held up very well. This last time, they came out and coated a 1300 square foot working garage. It started out with a really rough floor that had been through a fire about twenty years ago, and there were lots and lots of cracks. When they came out to look at it, they said they didn't guarantee the cracks, and that is fine because I know once the cracks start, it is really hard to stop. I was just a little disappointed that when they filled the cracks in, it wasn't done evenly. I didn't call in and complain or anything like that because it's kind of all too late now, and it does look 100% better than it did before.
