Help - Floor tiles coming off !!

[SarahW]

Should he have put anything on the concrete like a primer ?
Why have they raised up ?

If they have raised up sarah...they are tenting...how tight did he cut them to the walls......

Wether or not to use primer depends on the adhesive one's using. Some adhesives are "primer free" on certain surfaces.

As for the tiles raising, I'd say the same as Dave. Did he leave expansion joints/space along the walls?

We all know that floor tiles should be solid bed fixed, in other words no voids or do we? sounds like your tiler didn't.

And priming is always recommended on dusty and porous surfaces.

 

[SarahW]

Not very,but the skirting board is on now so I can only see in a few places

But the walls had just been plastered and that didn't go all the way to the floor because there would be skirting board.

Sorry Benny - what does solid bed fixed mean ?

 

[DHTiling]

Time for a tiler re-call sarah ......get him back out and see what he say's.....

Sorry Benny - what does solid bed fixed mean ?

That the adhesive has full contact with both the tiles and the substrate.

 

[Benny]

Solid Bed means that the entire floor and and back of the tile should be completely covered.:yes:

There are gaps in the adhsive and you can still clearly see and feel the lines and groves in the adhesive
