Thinset Between Mosaic Tiles

When i weave my lines i like the thinset to be smooth especially where there s more open space.

Thinset between mosaic tiles.

Thinset is slow to set which leads to tile sag on vertical applications. Basically you could push down to bare floor or close to it. Thinset is inexpensive and it fills in gaps and depressions. A 4mm trowel is perfect size for most mosaics.

Once i set my tesserae into the thinset i leave them for a bit before attempting to go in with my various implements to smooth it out. When installing glass mosaics excess thinset will bleed through the grout lines and create a disjointed uneven tile project mess. If you attempt to set wall tiles using thinset without spacers you ll end up with a bunch of tiles that have slid into each other before the thinset has had time to set resulting in a giant mess. Thinset is a bonding mortar which means it is a portland cement the same as used in concrete with polymers added to make it sticky and extra strong.

Smooth thinset in between lines and tesserae. Your thinset should be like peanut butter. Expert tile setters recommend a 1 8 inch v notch trowel thinset application in even strokes for installing glass mosaic tiles. I have no reason for this other than personal preference.

When used to tile walls it s strength allows you to set tile and if you re good with eyeballing you can set tile without the use of spacers. Walls wainscots dry backsplashes are key areas where tile mastic tends to be used. For outdoor and wet mosaics thinset is recommended instead of adhesives.
