The grout where the walls and floor meet in our tile shower was deteriorating. My project for the week is removing it and sealing the shower, then replacing with silicone caulk.
One big concern I have is how much grout to remove. I've got it now where there is a nice 90 degree angle between the surfaces, whereas before it was a 45 degree slope of grout. (I'm using a handheld grout saw just for this small area.) Also, when done, should I seal the remaining grout before caulking?
In some places this is the best I can do (wall and floor almost flush), in others there is still more grout. Do I just stop here? I'm worried about going to deep and hitting the wall behind or the shower pan.
