Self Level On Top Of Existing Floor Tiles

[dave l and l]

Been asked to go a job this morning but I am too busy. When I spoke to joiner I told him that the old floor tiles would need to come up. And he could go from there.
He just phoned me there and said another tiler is going to do job. His idea is putting a self level old tiles and tiling on top of That.
I have not heard of that before. Anyone ever practised that before. As I said I ain't doing job . But the joiner is asking me for advice as he doesn't think it sounds very clever either

Tbh it doesn't sound right.
If a jobs worth doing its worth doing right

I would rip them up then level then tile but if you must tile over floor tiles why level first ?

 

[dave l and l]

I am the same. Not seen job so not really sure. I am guessing the last floor is uneven. Would the self level even bond to existing floor tiles

If the floor is sound there's no reason why it can't be. Prime + grip or slurry cost then latex. A long as there's no height issue

Could have been tiled by me

here it is normal. tile on tile.
If the old tile. They are stable.
primergrip Mapei, do not use self-leveling (not convince me). Use mortar fibered type keralevel kerakoll or Planitop Mapei. then tile

Seen guys who have tiled on tile, the existing floor tiles were sound...

Yeah I've done it. If everything's sound then it's all good.
