Do I need to prime concrete floor before tiling?

Primer is absolutely necessary if you have an anhydrite screed (aka calcium sulphate). This is a liquid screed pumped onto the sub- floor that self-levels.

What type of thinset do you use for tile on concrete?

WarmlyYours Radiant Heating recommends modified thinset mortar for nearly all tile and stone installations.

Do I need backer board for floor tile on concrete?

Whenever you’re laying tile on a wood subfloor, you need to first install cement backerboard to prevent leaks and water damage that could harm your flooring and the structure of your home. Unlike wood or drywall sub-surfaces, cement backerboard will not rot, warp or grow mold and mildew when exposed to water.
