what is the case in majority of your jobs when you lift tiles?

[Mr T]

thank you rookery how bad would a floor need to be for slc to have to be used? or is it just a personnel judgement?

 

[Rookery]

No greater than + / - 3mm under a 2 mtr straight edge according to BS. If you've got the odd divot here n there but the rest of the floor is ok you could fill them with rapid set such as Ardex X7R, it goes off nice and quick. Basically the flatter the floor the easier it will be for you to tile. Dont confuse flat with level though.

I'm amazed that even stayed up....

It didn't. Was flapping around all over the place. I went in under instructions from a national, high street tile supplier contracted to ripout and re-fit tiles. How the customer managed to get that supplier to take the bill on the chin i don't know. Was the purchasers Son who did it orginally.

Sorry misunderstand, I'm not advising to use a grinder on plaster board unless you have a very steady hand and don't mind dust. I've done it myself in past with success full results
