Tile Over Tile. Looking For Ideas.


Anyone feel ok installing tile over tile?

From time to time I get a client who just hates the idea of removing a solid cement and wire tile sub floor during their remodel. I can see their point but, I have reservations on doing it. Anyone have useful suggestions on how to do it?

Thanks

Mike

Then problem with going over is that now you own all the problems that are hidden below. Hardwood floor mag had a good story on this. In the end it is better to start off fresh.

Those old cement floors are solid as heck. We often chip the tile off then fill any voids or divots from removel with thinset. Then tile away.

Re: Tile Over Tile. Looking For Ideas.


I've done it in my own house. Old mud bed with fugly tile, all of which was solid. Didn't see any purpose in demoing a sound substrate. Applied a bonding agent, then used latex modified thinset to set tile. This was several years ago. All looks fine thus far.

if the tiles are mosiacs, the floor sound, and the higher floor doesn't cause a problem, sure I'd do it.

I dont think I ever seen exactly what you guys are talking about. I assumed it was a duro rock underlayment. What are these mud beds? These are different then the cement board right?

First thing, asking this in the tile section is better than "general discussion".

Second, try this product as long as all the prerequisites are met:

Mud beds are were when they used to block between or over the joists and then fill with concrete over which tile was laid. I even saw one where it appeared the tile had been set in the bed.

That was the case with my place. Mosaic tile set flush with the hardwood in the adjoining hall. Installed new glazed tile that was about 5/16" thick. Raised the elevation of the bath floor around 3/8" total.

Simply removed the oak threshold between the rooms, ripped a piece of oak the thickness of the new floor & used it as a filler along the front edge of the threshold, which was reinstalled after the floor was done. Undercut the door a hair & wrapped it up.

Done it once, don't like to do it, although no problems 6 yrs out.
Seems to me I used a product that said tile to tile bonding.

Not too many around here anymore, either. Still a few good tile setters who know how to do them, but doesn't seem to be much demand (except maybe on the multimillion dollar jobs that we are never on).

Re: Tile Over Tile. Looking For Ideas.


Did it at my house, not sure if I'd ever do it for a customer.

Wanted to see how well it worked.

Had slate floor all around wood stove, scuffed the slate with grinder, used level crete primer as directed, poured level crete, then thinset, and tile. I chop kindling with a small hatchet on a block of wood on the tile. Have yet to see a grout line pop or a tile to crack. This installation was done four years ago not one problem. So I'd say it's aok to do, but then again I'd think twice if it was a customer.

Re: Tile Over Tile. Looking For Ideas.


The main problem with the mud bed is that most of the time the weight has sunk the floor substauly and adding inches of mud to level the floor doesn't seem to help the cause .
Then around here most of the plumbing in the floor is about 100 years old , buried in cement and not getting better with age.
leveling the floor is a problem because the area at the bath door tends to be the lowest point and when built up you will have a step at the door .
Most of the time i will use a bonding agent on the old concrete with a layer of wire lath and 3/4" of portland sand mix with thin set for the tile .

Most of the time we are moving the fixtures around and at that point we cut the tops of the beams to flatten /level the floor
and double up the beams back to bearing .
Most of the time Team/ craigslist will just throw some slime in the room over the old tile trying to get it flat for cheep money . John

done it on a high rise. was a concrete floor with tile down. i just tiled over it, and it worked good, cause the transition to the wood floor was more even.

Re: Tile Over Tile. Looking For Ideas.


I never done it and I frown upon it...especially when I see tile set over glazed tile...I dont think thinset grips on glazed tiles too well...besides you never know whats underneath...

I've done it a few times. Not my favorite way to do it but as long as you use a good bonding mortar then you should be ok.
