Hi Everyone, I was wondering if someone could help please. I have a slight raise in my bathroom floor, and the grout inbetween the tiles in that area, always ends up cracking after a few months. No issues at all with the subfloor or the tiles being loose - they have been down for over 10 years. If there a special type of grout I can use here? Or a grout alternative which is more flexible? Thank you!
there must be some flex for the grout to crack. If you know the make and colour of grout, see if you can get a colour matched silicon and use that instead.
You can get a grout additive that makes the grout very slightly flexible... it's designed/intended for tiling on wooden floors, where there will be some movement. I can't remember what it's called, but now you know what to look for it shouldn't be difficult to find! Cando
