Thermonet under 12x12 ceramic
Hello!
Our company is generalling a very high-end kitchen remodel. The job was "finished" last year, but the flooring company sent out a rookie installer and there were many problems with the floor, including, but not limited to ruining the heat mat during the re-dos. Homeowners wanted to wait for total floor redo until they were on vacation, which is now, because they don't want any more stress.
Current (experienced) installer has removed the floor, etc., and has laid the Thermonet heat mats. He wants to use a 1" square notch trowel for the mortar under the 12x12 Atlas Concord tile. That much mortar will make the floor too high and we won't have enough clearance to get the appliances (dishwasher, wine cooler) back under the granite tops. Installer says that much mortar is a requirement for that kind of tile.
Q: What size square notch trowel is required to lay this tile over the Thermonet mat?
