I recently applied a concrete patch to a rough/very uneven piece of concrete beneath an old flange I ripped out. I originally was going to apply a concrete leveler to the floor so I didn’t ensure the patch was completely level under the flange. Then decided I didn’t need the leveler (forgot about my patch issue).
My flange rocks a bit when I insert it dry - maybe a 1/4 inch gap in one area due to the concrete patch being higher there.
Will I be able to install the toilet as is? Should I try using mortar to raise up the section of the flange that is slightly lower? Do I need to use concrete leveler across the entire floor to even this out? enter image description here
