Pressing tile into the thinset
Plastic spacers can create uniform joints between tiles. Desired joint widths can vary, depending on the type of tile and desired look.
Once the tiles are in place, tap them flat with a grout float, rubber mallet or padded bar. After setting a section, gently clean up any thinset that has squeezed up between the tiles, using water and a nylon brush, cloth or damp sponge. If you are laying translucent tiles, take care not to scratch the tile's surface.
Thinsets usually require at least 24 hrs for curing at 10 to 30 C. Low temperatures retard the curing time of tile adhesives.
