Re: Tile over enclosed uneven Painted Concrete Floor
You can’t depend on any adhesion to paint so yes, you have to remove or seriously scuff the surface of the painted surface before applying tile to it.
If you need to level the concrete before applying your tile than you need to level it with a concrete mix of either type 3 mortar/sand or a premix compound with concrete adhesive and, preferably, an adhesive additive. Nothing else will stick to concrete in a reliable manner if your applying ceramic or whatever tile since your essentially bonding concrete to concrete
