please could anyone tell me what sized notches i need to lay ceramic floor tiles on a pretty level sound concrete floor,cheers.i have been told conflicting views and would like reassurance

Pretty much all agree it should be 10mm notches.

 

[gcol]

Yep 10mm radius notches.

go for a 50mm notch, then let it sink, it wont be level, but it wont move when set
