levelling solid floor covered in vinyl tiles

[WELLY417]

Hi
I need to level an existing concrete floor which is covered with vinyl tiles. The floor slopes and undulates which means that the thickness of the leveller will need to vary from almost nothing to about ¾ of an inch in places.

First question is should try and level on top of the vinyl tiles or remove them? They seem well stuck down and even if I made the effort to chip them off, the adhesive underneath is impossible to get off (and I’m not even sure if this would provide a better surface to try and get the leveller to bond to?)

Secondly, what to use? Self levellers only seem to be suitable up to about 5 mm and normal cement screeds seem to be recommended to be laid at least a couple of inches thick so I’m caught between the two.

I intend to lay some sort of wood / laminate on the floor in question. Perhaps I a barking up the wrong tree all together and some sort of underlay or matting would be a simpler solution?

Tips from anybody who has come across a similar problem would be much appreciated.

Thanks

If the tiles are well stuck down I reckon you could go over the top with this stuff http://www.pureadhesion.co.uk/product/198/mira-x-plan-self-levelling-compound-25-kg
If you are unsure though, you should always check with the manufacturer.

thanks gcol, that looks just the ticket. Do you know if this stuff or similar can be bought at major diy outlets or only available via the website you gave the link for?
