I am going to tile a bathroom floor (wooden boards). I am planning on using Hardiebacker on top of the floor boards prior to tiling.
My question regards a small area of the floor which is the hearth from an old fireplace, this is only about 0.5m square and is below the level of the surrounding floorboards by about 15mm.
I know I could use SLC but for such a small area could I get away with a layer of standard sand/cement mortar given that I think I can get it reasonably smooth and flat over this sort of area and that it will covered by the hardiebacker prior to tiling.
