Right, got on order some 600x400mm ** 10mm calibrated ** black brazilian slate tiles for the kitchen. Apparently these are very regular in size.
I know little about current tile adhesives.

1. What would be good for laying these ?
- Obviously cement-based curing rather than "drying".
- some areas will need to be built up by up to 5mm (due to the floor dipping slightly in one corner)
- not too expensive !

2. Should the sand/cement screed be sealed / primed first ?

Cheers,
Simon.
