One question we get asked all the time is if we can make a crack disappear.  For the most part the answer has always been no. We can make a good repair and finish it as close as we can to the original color and surface texture. That was before Roadware MatchCrete™ Clear came along.  The photos below were sent in by a concrete polishing contractor. By using MatchCrete™ clear and sand that matches the surrounding concrete, the polished repair blends in very nicely with the concrete slab. When the floor is in service, you will have to look very carefully to find the repairs.  Try some Roadware MatchCrete™ Clear on your next polishing job. With a little technique and experimentation, you can get results like this.
