I have a few small areas where the grout between tiles keeps cracking. I've repaired this numerous times, it lasts about 6 months and cracks again. I understand that this is likely due to poor subfloor, settling, etc. The tile is not loose and I'm not going to rip up the floor. I'm wondering if there is a product, or process/additive for grout (something like caulking), that could be used to permanently fix this in these small areas. Any advice for a more permanent fix than simply mixing up a small amount of the grout and redoing things again for another 6 months? via /r/DIY http://ift.tt/2BFgnu1
