Do not buy this product! I tried this on old and new grout and found that it sticks will to fresh epoxy grout, but poorly to old traditional grout. I followed all the instructions and cleaned the old grout very well. In addition, the method does not work well because it is impossible to make a straight line on the grout edge using the scrubbing technique described. So even if it didn't peal off completely from the grout, as it often did, I wound up with a grout job that looked like something a child did with a box of crayons.
