Laying tile on top of tile (Flooring)
 
I want to know if I can lay ceramic tile on top of old thin, thin, think tile because the current tile has little to zero damage. Is this possible?

Ceramic can be set over existing ceramic using unmodified thinset mixed with liquid latex---
Kerabond and Keralastic by Mepei is a good example.

The existing ceramic must be perfect---Scuff the old tile with course sandpaper first--An angle grinder with 36 grit paper (two disks back to back) makes for a quick scuff.

If you are trying to safe time with this I would recommend spending the extra time to remove the old tile.

Most ceramic tile does not have a exact thickness. This variation in thickness can cause big problems and crack your new tile

Could you explain why the slight variations would cause the new tiles to crack?

I never heard of that problem.---Mike---

The thickness of the old tiles may not be exact. This is something you may notice by feel but if you try to attach a new tile onto it this could cause a tile to not have full contact to the surface underneath. Then the tiles may crack. This is why subfloor prep is so important in tiling.
