Tile – a recommended height for tile edging


I'm trying to put up a tiled mosaic back splash and I'm trying to figure out the profile height for the edging. My tiles are 1/4" (6mm) thick.

Should I be getting an edge where the profile height matches my tiles or should I get one slightly thicker to account for the thinset?

With larger tile that may span irregularities, I would advise 1/16 higher to end up flush.

With mosaics, I would go for the same height. Too much thinset with mosaics makes a grout line mess, oozing up and needing extra cleaning.

If you are using unbacked glass mosaics, be sure to skim coat the whole field with a white thinset before pulling.a notched trowel for the final setting bed. Then flatten the ridges for a smooth, void free bed that won't show variations through the glass
