adhesive or thinset mortar to adhere it to the slab. If installing in a wet location,
ensure the slope of the mortar bed is maintained to direct water to the drain pipe.
Note: For wet location installaions, WarmlyYours recommends installing a secondary

manufacturer’s instructions. This will protect the mortar bed from any moisture that
may seep through the tile, which could cause mold problems over time.
