Tile over Composite, vinyl tiles ?

[coffee4me]

Hi,

I would like to tile (ceramic tile) my bathroom floor (8'x6').
For now, it has those older composite, vinyl tiles glued to a cement floor.
Can I tile over this ?
What adhesive do I use ?

Thank you

it is not recommended to tile over vct tiles bonded to slab try to heat up the tiles and use wide putty knife and pry them up also will have to deal with cutback adhesive the black glue. VERY IMPORTANT TO NOT GRIND OR SAND THEY MAYBE ASBESTOS. u can get them tested for asbestos in your area usually around 30 bucks.

Hi there, gotta first name we can use? What kev said. I would remove the tiles, then use a modified thinset to set your new tiles.

Hi,,,,
The name is Danny...

I will pull up the old tiles with a heatgun in a couple of days.
Any other recommendations if a heatgun doesn't work ?

Thank you

it will

A propane torch also works, but don't set your house on fire. It will really slow up your job.

I'm in the middle of pulling up those old composite tiles.
It seems like I have another layer underneath it...

There is still a lot of adhesive left on the floor. How do I get the adhesive off that is still sticking to the floor ?

Thanx,,,,,,

How "clean" does the concrete have to be before I can tile ?
There is a lot of old, black adhesive on the concrete from the old tiles that I pulled up.
I will scrape off as much as I can. Do I still need to use a solvent/adhesive remover to clean it better ?

Thank you

From what I've read here, if you have it basically scraped up so you can see most of the concrete, and you use a thinset rated for use over cutback (well, plus if the slab will absorb some water), then you'll be okay.

I pulled up all the old tile that was there (3 layers!!!).
Pulled up the toilet and cleaned everything.
I scraped most of the black adhesive off the concrete.

The hole where the toilet drain fits in, seems to be a bit higher than the rest of the floor.
Is that going to give me any problems when putting tile down ?
Or does it have to be flush with the rest of the floor ?

Thank you

check it with a level and skim around it with thinset to make less hassle setting are u using ditra or afm?

[coffee4me]

AFM ?

The floor is concrete.
I will skim around the toilet drain.
Other than that, I can just put the tiles down on the concrete floor, right ?
I'm using an adhesive that is suited for cut back.

[coffee4me]

Any reason why I should use AFM or Ditra ?

Putting the tiles down now, with the proper adhesive should be OK now, right ?

Thank you

You need to make sure that the toilet flange on the floor sits up about 1/4" above the tile that you put in.
