I never write reviews. Our new kitchen was installed in November. We wanted to keep the floor because it was in great condition but the grout was terrible. We went to the tile store, found the color grout we wanted and Grout Shield matched it perfectly. I used the product this weekend and finished our kitchen floor. IT LOOKS BRAND NEW! I am simply amazed at how great this product is. It takes time to do it, but the results are worth it. I am now going to tackle the fireplace tiles. THANK YOU!!!
