  • A: Necessary? Recommended, definately.



    As Jason said above, take a look at any tile floor or wall you can that has light colored grout. Chances are, it wasn't sealed and it probably shows stains. Darker colors will last longer, but it is still a helpful in keeping your tile looking nice. Now, if you have decided to seal there are a few different options and I would recommend each option based on the size of the job. For small jobs, such as a shower stall I would buy the applicator that has a squeeze bottle with a little brush on the end. This is not the easiest way, but it is perfect for small bathroom jobs because I feel the seal lasts longer. The next option for medium sized jobs is an applicator that is a squeeze bottle with a roller wheel at the end of it. I don't think it is quite as effective as the brush but it still works fine in a job about the size of a kitchen. The last option, and only used on large jobs like whole house projects is an inverted airesol can. It will cover a little bit of the tile as well as the grout and will be to be cleaned ith soap and water, but if time is money, this option will save apt of time on large jobs. Now, that you have sealed your grout you are good for about a year. Make yourself a note to clean and reseal every year and you tile will stay looking great. I hope this was helpful.

  • A: Grout sealer?



    Ask anyone with lighter colored grout that did not seal their opinion: they will almost always say YES! Id advise anyone with a lighter grout color to seal for a few reasons. Sealing grout keeps stains from penetrating. In a shower, it can keep grout from getting stained by water spots, mold and mildew. Sealer definately makes cleaning easier and keeps floor or wall looking newer, longer.

    I'm also going to venture an opinion... I just used grout to fill in holes on a concrete countertop. So far, it looks like if you get the grout wet again after it's hard, it turns back into cement. Maybe I just didn't wait long enough...
    If you DON'T seal grout, I wonder if it might happen.
