This is an easy one. Find someone in your area who does resurfacing of ceramic tile. They must first acid etch, clean existing grout, regrout, put down a primer and refinish with a good acrylic finish. This stuff is guaranteed for life if done properly. Make sure you get a list of former customers, and CALL THEM. I have had many done and even after 5 years the surface cannot be scratched.
