I have a question. May I seal grout in my mom's living room with polyurethane? It is a HIGH traffic area and I am concerned that the grout lines will be filthy very fast and I know that I need to seal them with something. :confused:

U can get grout sealer at home depot.

Do you know exactly what kind of grout was installed, some are already stain proof but do not use urathane.
