Mosaic tile, combination of glass and stone tiles, how to adhere

We have just purchased some new mosaic tiles from one of the big box stores, unsure of applying the mortar. The tile state to apply mortar with 1/16 inch v-notch trowel, however I've been told to apply with straight edge trowel so that mortar ridges don't show ????

What's the real answer ?

You want to use a thin set trowel (with the grooves), so that when you press the tiles, the grout has space to go to.

Any excess grout can be easily wiped clean with a tile sponge.

Bill,

WHen setting glass tiles be sure to use a dry powdered thinset that you mix with water to install the tiles. Never use mastic / pre- mixed anything.

After keying in the thinset, comb in the trowel ridges. That will meter out the correct amount. Then flip the trowel over and gently flatten the ridges without scraping away the thinset, or making hills and valleys. When you press the tiles gently into the thinset you won't see the trowel ridges.

For all information tile related, head on over to the John Bridge Tile Forum.

If the glass tiles are paper-backed, you are free to use a notched trowel, but if the glass tiles are individual and not backed, the thinset would show lines, so you have to use white thinset and back-butter each tile so it looks uniformly patternless.
