Grout then Silicon Cracking Can't Find Solution
Okay, so I have a bathroom that is pretty newly redone, for reasons I dont need to get into, I can not go back and speak with the contractor to get this fixed so its now on me.
I have a sunken shower with a small curb inside. The bathroom floors are 6"x24" porcelain tile. The tile guy was okay, but he didn't line up the tile well where my glass tile and porcelain tile meet to make a 90 degree angle. He also just used unsanded grout and not silicon for this plane change. After two months of use, I guess the movement in the porcelain floor cracked the grout.
I tried to remove the grout with a grout saw but was unable to. Instead I tried using 100% silicone over it. However, that only worked for about two weeks where now it looks like this. What can I do to correct this?? The gap is about 1/4". Should I once again try to scrape everything out and then use foam rod backer and silicone?
