Allow the first layer of mortar or self-leveling cement to cure before installing the tile. To install the tile, apply a second layer of thinset with a 1/4" square notched trowel. Perform and record the third ohm test.
TIP: Experienced installers may wish to combine steps 2 and 3 by covering the mesh and installing the tile with thinset in one step. A 3/8" square notched trowel is recommended for a one-step installation.
TIP: Clean thinset from between grout joints with a wet rag while installing tile, when thinset is wet, in preparation for the grout installation. NEVER use a utility knife to remove cured thinset from grout joints.
