We are remodeling our home ourselves, and chose the Merola penny round tile for a bathroom. We made sure the floor was perfectly level, dropped chalklines, dry fit the tiles and used a 3/16" v-trowel with latex mixed thinset applied evenly. The mesh seems to have had some play in it, and because there aren't spacers made for this kind of tile, once we grouted we realized the spacing between the sheets was too wide in some areas, interrupting what should appear to be an even field of penny tile and it just looks terrible. There's no good resource online or in books (or in the tile stores...they just say how hard it is to use these mesh sheets with the round tiles, even for contractors!) We love the look and want to redo the floor, but are afraid we'll have the same less than ideal results. Does anyone have any tips and advice for us? Many thanks!
