John and his crew coated our new-old 4 car garage yesterday and it looks amazing! We added a 2 car garage onto an existing 1960 garage and the old floor was a mess. John's gigantic concrete grinding machine and his expertise prepped the floor and did his magic. He got here when he was supposed to and was in and out in one day.....as promised. The results is first class and I would highly recommend his company.
