SILICONE OVER PERIMETER GROUT LINES?

I just regrouted grout lines that failed in our bathroom and leaked through downstairs ceiling.The bathroom has an open shower (no curtain or walls) and it drains in the middle of the floor. There is ceramic tile on the wall and the floors. I removed cracked grout on the entire perimeter (the main culprit of leak). I used pre-mixed sanded grout. After sealing (and letting dry for a day) should I apply a silicone bead over the grout on the vunerable perimiter where wall meets floors and other vertical lines where there is a corner?
Thanks in advance for suggestions!

This continues a thread from a few days ago by the same, well named per – “xistent.”  For those seeing this for the first time:  http://forum.brownstoner.com/question/1x836Cv3kXA=/mysterious-leak.  I regrett my accusation that Limestone Cowboy has rocks in his head, but not what I said about the unfortunate problem.
I am in the directory under Shower Stalls.
 

Greenmt I appreciate your feedback but the situation at present is the water comes through on the perimeter when excessive water comes there. With the bath room the way it is and the location of the drain with the pitch leading the water there, water shouldnt necessarily come to the perimeter. We’ve had somebody cleaning for us that gets caried away with the water and so the water got through those cracked grout lines on the perimeter. Obviously they didn’t do a good job grouting or installing a good pan/drainage system. At any rate, we can’t redo this now as a bathroom tile & redo is not in the cards now. At a future date, yes, but not now. That said, I can make sure no excessive water hits the perimeter joints and seal them as best as possible. I regrouted and was considering wether I should apply silicone over the joints. Suggestions appreciated. Thanks

What the heck, clean off the perimeter joints you will be caulking with laquer thinner to ensure a good bond, and caulk away. Be sure to use a tub and tile caulk and allow adequate dry time. If you can’t afford do a proper repair now, certainly this could not hurt, and may lessen the ongoing damage It’s already wet, and water is draining to the floor below). Who knows it might even work.
