I am in the process of having a new tile shower installed. I am using glazed ceramic tile. When I checked with the local big box home improvement store, they sold me a spray bottle of "Grout and Tile Sealer" to use on the finished shower. This Grout and Tile Sealer says it is for grout and unglazed tile.
Should I go back and get a grout sealer only? Or should I apply this product to both grout and glazed tile? Won't it just wipe off the glazed tile, and serve no purpose? The clerk at the store said this would help protect both grout and tile and was good for a shower application.
Thanks for any advice/ideas!
