Not strictly plumbing but I'm sure there's a lot more experience out there in all sorts of stuff.
Anyway, I will want to replace floor tiles in the kitchen. I did think about tiling over but would mean the floor level quite high compared to the next room.
I know its going to be hard graft getting them off - plan to use a heavy sds drill I have (the screwfix one). But my question is once they're off will the resulting surface be ok to start laying new tiles on? Its a concrete floor. Or will I have to spend more time preparing the surface (laying a thin screed or something else?)
