I'd like to watch you back butter glass tiles. I'll bring the lawn chairs and the drinks to see that Teetor. :laughing:I've used about everywhere too without problems. I'm guessing that rbs didn't back-butter, how else could you get fogging?
It's actually based on bonding. Normal tile and thinset bond due to the porosity/water absorption of the tile, the thinset works it's way into the pores of the tile and creates a good bond. (This is why porcelain takes a different method to install vs ceramic) porcelain to be porcelain must absorb less than 5% of it's weight in water to be classified porcelain, which in turn makes it harder to get good bond without doing some different things during the installation. Glass takes this up another notch being about zero absorbent with virtually no porosity, so this creates the need for even more specialized thinsets with glass tile.Don't you have to go with a special thinset when installing glass tile. Meaning not the same you would use on other tiles. Isn't it because of the translucency of the glass tile?
Hydroban over cemetboard, then set em with laticretes grout and admix to make colored thinset to match the same grout mixed with their additive for grout.
