Collins Concrete installed a polyaspartic coating in my garage over a year ago. It has held up extremely well, as advertised, and I wouldn’t hesitate to recommend them to anyone in the area. They stand by their work as well, which can’t be said of a lot of companies lately. I recently had some damage from a void (a pocket of air) not found under the surface of the concrete during install. They came out and fixed it and it’s like it never happened!
