Does mosaic tile need to be back buttered?
This back-buttering step is best used for all glass mosaic tile, but is essential when using fully transparent tile, in order to keep any remaining trowel lines on the substrate from showing through. Back-buttering also insures near-complete (95%) surface adhesion between tile and substrate.
Do you grout mosaic tile sheets?
The majority of mosaic tiles are netted with a 1/8-inch grout joint. In these cases, a sanded grout is needed to fill the joint. If your mosaic tiles have a smaller grout joint, such as hand cut glass mosaics, use unsanded grout.
Do you put thinset on back of tile?
For large format tile, glass tile, natural stone or any tile set on exterior surfaces, “back buttering” the tile is recommended.
