I have just taken up the old foor tiles in the kitchen which have been layed in a concrete floor. the concrete is not in the best of shape, and i need to put down a new slate tile foor.
The concrete foor in not that level. it has a type of bitchamin compund on top of the concrete which the old tiles were stuck to, does this matter?
Would the best thing to do be to put down a self leveling compound? If so could you give me some advice on how to do it or a type a compound to use?
I am looking at taking up my quarry tiled floor and laying slate tile over the concrete. I have been told that you need to dig out all the concrete. Seems extreme to me and I thought putting screed on top would be ok.
Just wondering how you have got on as it seems that your query is similar to mine.

David, I'm having to do the same thing and my sub floor is a kind of bitumen, it's black and plastic in feel. Our house was built in the late 1970's and I reckon it's some form of early DP. I'm trying some test areas and mixing 4-1 sharp sand and concrete for the screed and laying this directly on top of the bitumen/plastic coating. I'll let you know it it all stays bonded to the base.
