Correction for tiling an unlevel floor
My computer is FUBAR---sorry---go to the tiling section--that is a 'sticky' at the top--Bud Cline wrote it,well worth reading.
Tile is set right onto the Self leveling compound,no need for a backer--
Add sand to the deep areas ---stretches the product and makes it stronger----
If you use deck mud--pack the deck mud on top of a wet layer of modified thinset---that will aid in bonding the deck mud to the subfloor---
