Would I still need to use an uncoupling membrane like Schluter Ditra with this over concrete?

Thank you for your inquiry regarding MAPEI Products! Your first step is to prime the concrete subfloor, let dry and then pour your Self Leveler. Once cured, you can install your Schluter Membrane over the cementitious Self Leveler using an unmodified thin set mortar such as the Mapei Uncoupling Membrane Mortar. Once dry, you then install your tiles over the membrane. Schluter recommends using an unmodified thin set mortar, Mapei recommends a polymer modified thin set mortar to install your tiles.
