Do I Need Backer Board Before Tiling on Self-Leveling Concrete?
Asked by RandomUser92
I'm in the process of redoing my bathroom, and I've noticed that the plywood subfloor isn't level. My plan is to lay down some self-leveling concrete to fix that before installing tile. My question is, can I simply lay the tile directly on the self-leveler, or should I put down backer board first?

For sure, you’ll want to use an uncoupling membrane as well. It acts as a buffer to prevent cracking between the tile and the substrate.

Definitely put down cement board before the self-leveling concrete. This helps prevent flexing, which can cause issues later on when you lay down the tile.
