Thinset Between Mosaic Tiles

Expert tile setters recommend a 1 8 inch v notch trowel thinset application in even strokes for installing glass mosaic tiles.

Thinset between mosaic tiles.

If it is too thin then you could have possible issues with mosaics and flooring. When i weave my lines i like the thinset to be smooth especially where there s more open space. When installing glass mosaics excess thinset will bleed through the grout lines and create a disjointed uneven tile project mess. For outdoor and wet mosaics thinset is recommended instead of adhesives.

Mastic is very sticky grabs fast and is quick setting. This is particularly important when working with glass mosaic tile which is non porous and difficult to bond securely. Smooth thinset in between lines and tesserae. Walls wainscots dry backsplashes are key areas where tile mastic tends to be used.

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. Your thinset should be like peanut butter. 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.

Thinset is inexpensive and it fills in gaps and depressions. A 4mm trowel is perfect size for most mosaics. I have no reason for this other than personal preference.
