    CrackWeld® Concrete Crack Repair Kit Feedback: "This product works wonderful. I wish I had tackled the cracks in my garage floor sooner. I had hairline and some wider cracks which seem to grow larger every year. I read all the instructions and watched the videos. The project was much easier than anticipated.
