Ceramic over Ceramic?
I have a customer that has tile down on a concrete slab.
I would like to avoid demo.
Can I tile over the existing tile?
and what prep steps should i take?
Please help

Tile can go over tile. Just be sure that there are no issues going on such as cracks, loose or missing tiles, flakin grout etc. It has to be sound and in good condition or don't even consider it.

Absolutely it can be done.
One recommendation against it would be that if anything happens to the first layer, it will affect the second.
Best to have a fresh low liable start eh?

It can be done but I avoid it if I can. I have done it once a few years ago and the floor is still solid. One recommendation is that you should scuff the first layer with a sander so your adhesive will grab better. You should be fine.

I've done it several times with no problems. Even done marble over ceramic too. It's all good.

Sure, It can be done, but as previously stated the tiles underneath must be solid and no loose tiles, If the tile underneath is very glossy then I wouldn't do it.

I would do it as a last resort.
If it was more than 300 sq ft and I was too lazy to rip it up than we may tile over.
But the TCA approves this method so long as the tile is free of cracks and structurally sound. Take a golf ball and ping it off some of the tiles. If you hear any hollow noises, don't do it.

i've done it too. But before I did I went over the tile with a 12 grit disc on my buffer and primed and level qwicked the floor. That was about 6 years ago. Far as I know no problems.

Why not? Have you seen some of the shear bond strengths of good modified thinsets? As long as the first layer is tight and sound, it'd be no different than tiling over sheet rock or cbu.

I'm not fond of the idea myself but I'm also not fond of tearing out the ceiling with blown in insulation above it.

I would take a broom stick (without the broom) and poke the floor throughout and listen for a Hollow or loose sound when the pole hits the floor. If there are a few loose spote just remove the tile and fill with thinset.

Yah, I hear ya, blown in insulation blows!! Still, the vast majority of my jobs are complete demos - and something just doesn't feel right about tiling a ceiling over existing tile.

Awww c'mon man don't be skeered..
Now tiling over an existing pan scares the hell outta me  ...I don't care that it has "never leaked"...nope ain't gonna do it.
Almost all of mine are torn down to the studs too...just supporting that it can be done and you can still sleep at night. (a ceiling that is)

Sure have, but how does someone guarantee the original bond strength without a shadow of a doubt.
Plus we are forgetting that new adhesive can sometimes "pull" when curing.....
I have seen Vinyl down with no bubbles after 25 years....we lay a new sheet over the top and the new adhesive "pulls" the Vinyl up......rare...but happens....

Can't add much to the discussion that hasn't been said except don't forget the obvious. It's easy to do when you're wrapped up in a project.
If you add another layer of tile make sure it doesnt create any clearance problems with doors or anything of that sort.
