Ultimate Concrete Coatings did the concrete overlay for our porch, driveway and car-port area. All in all, it was over 1000 square feet. They did exactly as they said they would. They came the first day, sanded everything down and filled everything in. Then the next day they did the overlay and finally, they did the color on the third day. Everything turned out perfect and it looks very good. The price seemed OK. I've never had experience with this type of product before, but they did discount the job so I thought it was fine. One thing I would say is to plan ahead if you want to get this type of work done. It's a three-day process and they have to schedule it ahead of time, so they won't be able to come take care of it the next day. It was four weeks before they actually came and did it, but it was worth the wait.
