Don't use Concrete Texturing for concrete overlay. Had it done 3 times, because the sealer was all peeling off. Each time I had to pay for it (they blamed a poor sealer product, but wouldn't stand behind it). It started to peel off immediately after the 3 rd time and they told me they wouldn't take care of it. I'll never use them again, nor will I recommend them to anyone else. I suggest you find a more reputable company.
