DIYbanter - View Single Post - what to use to level floor by 10-15mm

wrote in message ...
I am trying to level our utility room floor. It is partially tiled the
rest being concrete. The largest variation in depth is approx 15mm. What
should I use to level this prior to tiling? Self-levelling compound says
no more than 3mm. Whatever is suggested can I use it over the tiles as
well as concrete to so using existing tiles to fill in some of the
depth?

If it were my place I would want to do it properly, not with tile
adhesive that may disintegrate after x years. Parallel strips of wood
fixed to the floor, get them all nice and level. Fill with good mortar
mix, levelling it to the battens. When dry remove battening and fill
that too. But... there are many options.
