I just had my garage floor refinished by Iron Drive of NJ and I couldn’t be happier with how it came out. Eric, the owner, was very knowledgable and did an excellent work. He did exactly what he said he was going to do, did it on time and for what he quoted, with no bs or extras. I was very happy that his treatment includes grinding off the old top coating(s) to get down to the bare concrete surface. The new surface is glossy looking but is textured enough to not make it slippery when wet. And it looks great. He also treated my covered concrete porch with a clear top coat after grinding off the old peeling epoxy layer. I would highly recommend using Iron Drive of NJ.
