OoAchewOo 0 Report post Posted August 5, 2012 Hi gurus,just started my reno recently, and notice that my contractor had put up some of the tiles in my kitchen, just wondering we always said that the back of the tiles are supposed to be filled by cement, how about the extreme edge of the tiles?? i notice that some of my tiles edge produce hollow sound when i knock it, would like to check whether this is acceptable??? if its not a big issue & would not cause any problem then probably i would just live with it..dont want to be too unreasonable and picky.. =) Share this post Link to post Share on other sites
