We have tile throughout the house except bedrooms. Before we moved in, we bought a product at Home Depot (not the most expensive and not the cheapest but the one in the middle). It was silicon based. We applied it with a sponge mop over the entire tile and grout and ten a second coat over the grout. Lot's of elbow grease and several hours. In the process, we noted several grout lines that were not quite right. No problem getting them repaired under warranty.
