If I install WarmWire, how do i make sure the finished tile is the same height everywhere?
If you install WarmWire in a portion of a floor, you can spread thinset to make sure the finished tile is the same height everywhere. Use a 3/8 inch x 1/4 inch notched trowel, not a conventional 1/4 inch x 1/4 inch version. When applying thinset over the backerboard, hold the trowel up at a steep angle to apply more thinset. When working over the wire, drop the angle of the trowel somewhat to apply less thinset.
