Thinset Between Mosaic Tiles

Your thinset should be like peanut butter.

Thinset between mosaic tiles. 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. Thinset is slow to set which leads to tile sag on vertical applications. This is particularly important when working with glass mosaic tile which is non porous and difficult to bond securely. Expert tile setters recommend a 1 8 inch v notch trowel thinset application in even strokes for installing glass mosaic tiles.

When installing glass mosaics excess thinset will bleed through the grout lines and create a disjointed uneven tile project mess. Thinset is inexpensive and it fills in gaps and depressions. I have no reason for this other than personal preference. 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.

When i weave my lines i like the thinset to be smooth especially where there s more open space. 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. Basically you could push down to bare floor or close to it.

Smooth thinset in between lines and tesserae. 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. 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.
