Agreed. This is a friendly, helpful forum. Let's keep things factual and informative please people

He's right though about the prima donna bit!

Levelling a floor for tiling is part of the duties of a tiler it is classed as surface preparation and one of the current modules of the wall and floor tiler NVQ it isn't an optional extra that some tilers do and others don't which is why you have been met with some of the professionals on here questioning the ability of your tiler , you may well have seen his finished work but that only tells a small part of the story as what lies beneath is as important if not more important than what looks on the surface nice job as you want it to last if you are spending your money on it , you tiler is right the surface prep does need to be at a higher level of quality for large format thin tiles and to offer you a warranty on his work he should want to do his own prep work as if some 3rd party is involved it leaves you as a customer in difficult position if something goes wrong hope this helps

Late arrival here,
if the tiler has said that the existing floor is already of a good standard (in his words), then surely its only a bit of patching up here and there to bring some areas up?
This should be totally manageable by a tiler with even just average SLC skills?

The 'new' floor is good, but not good enough for 1m2 tiles. Together with the 'old' kitchen floor gives an area of 70m2. As the thread shows, the Tiler's said it needs to be perfect and they are not comfortable doing it.

I've now got Express Screed Ltd to do it for me next week using Rocatex C40 F10 Slow Flex Leveller

Fingers crossed they do it as professionally as they sound.

The only thing I can add is that you, via your tiler, detail clearly and in writing to your contractor the exact specification required and copy your tiler in as well. IE, finished floor height, any movement joints, maximum tolerance on flatness etc. Armed with that, you can check that the work has been done to spec or not and proceed accordingly

The rocatex leveller is an excellent product. I used it to level a terrible screed to take 1200x2400 tiles and now use it exclusively.
Good luck

Great stuff chaps, thank you.

They have specified +\- 2mm over 2M. Sounds about right?

Most of the guys work to 0.1-0.05mm over 10m, but I suppose you could get away with those tolerances 😉

I know, please accept my apologies bit of a typo there, it should have read over 20m.

You did know I was going to be a brain surgeon but found that the tolerances weren't fine enough for me.
