I have removed the tiles from my entryway and will soon need to have new tiles laid. There is still a layer of the old adhesive on the floor and I am wondering just how clean and flat the floor has to be? At the moment there is about 3-5mm of old adhesive in places.
Groggy, the tile likes the floor to be FLAT. Get the old stuff off if you can. :)
Ok, I was hoping it wouldn't be necessary. Thanks Bloke!
Groggy,
Sorry for such a short reply, I was in a hurry and left it for others to fill in.
Over here you can hire a machine by the half-day to scrape the floor clean--a possibility. Also, if needing an excuse for a Fein Multimaster this is it, use the scraping attachment. :D
The problem is that tiles, as hard as they are. crack quite easily on an uneven surface. If your tiles were laid on a cement board underlayment, just tear out the old board and put new. If not, scrape away. :wink: :(
I also commend you to this site for in-depth information if you need it. It is the U-Beaut of tiling forums: :2tsup:

Good luck.:)
I used the good old Ozito Rotary Hammer with a wide spade bit & the rotary function turned off, tip it over at 45°, pull the trigger & follow it across the floor. :2tsup:
Hey groggy, A couple of methods I've used (as well as cliffs)
1. fill with self-levelling compound
2. use a diamond cup grinder wheel (gasweld was getting some in cheap) - very messy though

Too small an area to hire something. Thanks for the link!Quote:
