I found two types of grout sealants:
grout sealant
grout-and-tile sealant

Has anyone any experience with the 2nd kind? It sounds like it would be
easier to apply -- just brush the thing on the entire surface. No need to
paint along the grout line and clean the tiles.

Does it have any drawbacks? Does it make the tiles hazzy? Any help would be
appreciated.
