Recommend leveling for my concrete floor before installing WarmWire?
Several major companies make self leveling mortar products. These are mixed with water to a pancake batter consistency and are designed to be poured over uneven spaces to level a floor. WarmWire has been tested with these products and is compatible. You can apply WarmWire to the existing floor and pour self leveling on top and then apply your finished floor, but the deeper the wire is below the surface, the longer it takes to respond from a cold start. You might consider pouring the masonry first, allow it to harden and then use double sided tape to secure the WarmWire wire on top. Then you could apply a thinset and tile/stone finish to the floor.
