New tile in entryway and kitchen and the job just finished. He repaired broken tile areas and replaced the grout in the dining/hall area. Only now do I discover the job did not include sealing the grout. [I]Should we seal?[/I] Everything I've read says to seal, but he says no... it leads to more mildew problem because it doesn't allow moisture to evaporate. I also discovered that the grout color in the kitchen turns darker with water dropped on it..I hate that. Will sealant keep that darkening from happening? And, for any of the areas, what will the sealant actually do? Also, [I]how to polish the old tile.[/I] The new entrance way was done in order to remove old tile and recover some of those to replace broken tile in this area. Nicely done. But some of the replacement tile is nice and polished showing off the dullness/haziness of the overall floor. I presume those shiny tiles had some hand cleaning before being replaced but how do I get the whole floor to shine again? Years of regular mopping may keep it clean but somehow does not restore the shine. This tile is a brick shape pocelin glaze of the highest hardness rating. How long does it take the grout to cure? It is a polyblend sanded grout. Thanks BJ & JC
