Grout cracking on floor edges not in between tiles - TilersForums.com

[diamondtiling]

Thanks loads guys for all the replies.... I had a feeling that it could have something to do with leaving room for expansion.

It was really starting to worry me because i had followed all the rules of using marine ply and was certain that there wasn't any excessive movement of the floor. This was my first attempt at tiling and thought I had done a really good job so glad it wasn't something more serious.

I've got some ivory silicone that should do the job.

Quick question guys... I have a walk in shower with mosaic tiles on the floor, these haven't cracked yet, would you recommend that I silicone these too?

Many thanks once again

ASAP! all wet areas have to be sealed
