I have since decided to install vinyl sheet flooring.
Vinyl tile on hardibacker.
Secondly once the self leveler is dry you can adhere tile directly to it.
For best results remove existing floor covering especially if it is in poor condition.
Examine the vinyl tile well for loose or peeling areas.
Custom s fiber reinforced levelquick is another.
Here is my concern.
Your vinyl floor will look like crap with wrinkles and indentations in it.
Hardiebacker cement board may be installed under or over vinyl composition tile vct and other resilient flooring.
You shouldn t add any backer board over the top of it.
Remove any wax build up or grease that may interfere with the bond of the mortar with the backer board.
The hardibacker has grooves and indentations.
No not a good idea.
If you are unsure.
Screw down any loose area into the subfloor.
Clean the vinyl well.
