How to apply glue to mosaic tiles
Glue should be applied with an even end of the spatula from the back of the tile. All types of mosaic tiles calmly withstand a double way of applying glue (on a mosaic and on the wall). If the glue layer is applied only to the wall, then glue white stripes that leave the gear spatula will be visible through the tile. In addition, double application of glue will allow tiles to clarify tightly with the wall.
