Help! Self Leveling Concrete over Redgard+Hardiebacker?
Can i use Self Leveling cement (plus primer) over hardiebacker that has been cocered in redgard/waterproofing membrane? Or do i have to use mortar (like for a shower)?
I am trying to raise part of my kitchen floor where the old cabinets were and the new cabinets are going. It is about 20 sq ft in an L shape, and i have to fill about 3/4" up to get level with the rest of the kitchen floor tiles. All of the area will be hidden when the new cabinets are installed.
I have already nstalled 1/2" hardiebacker on the floor and applied redgard waterproofing membrane with the fiberglass tape, and then put silicone on all the joints and soft spots/potential sieves.
