Thinset Between Mosaic Tiles

Basically you could push down to bare floor or close to it.

Thinset between mosaic tiles. For outdoor and wet mosaics thinset is recommended instead of adhesives. 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. Your thinset should be like peanut butter. Thinset is inexpensive and it fills in gaps and depressions.

Thinset is slow to set which leads to tile sag on vertical applications. 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. If it is too thin then you could have possible issues with mosaics and flooring. Mastic is very sticky grabs fast and is quick setting.

When installing glass mosaics excess thinset will bleed through the grout lines and create a disjointed uneven tile project mess. This is particularly important when working with glass mosaic tile which is non porous and difficult to bond securely. When i weave my lines i like the thinset to be smooth especially where there s more open space. I have no reason for this other than personal preference.

A 4mm trowel is perfect size for most mosaics. Smooth thinset in between lines and tesserae. Expert tile setters recommend a 1 8 inch v notch trowel thinset application in even strokes for installing glass mosaic tiles.
