Ok - second grouting question in as many weeks.
The bottom line of grout in my shower, right where the showerpan meets the tiles, is showing a lot of cracks. Water can now definitely get between the tile and the showerpan. I'm guessing this is because it's a new edition on a much older house, and now 2 years in it's "settling". Dunno.
My question: eventually I plan on taking a grout saw and redoing all the grout, but that won't be anytime soon. I'm planning on using a hairdryer to make it as dry as possible and then laying in a thick bead of silicone caulk. Does that sound like an ok approach? during the summer I"ll have the time to re-grout everything, but not now.
My only worry is it not being completely dry behind there, but I'm not sure hat I can do about it besides the hairdryer. I certainly can't rip everything out right now "just to check".
