I am redoing my kitchen and plan to lay vinyl tiles on the floor. Currently the floor is covered by ceramic tiles but I have been advised to remove them for best results. The present floor is slightly too high anyway so I'm OK with that.
The floor screed was originally laid 18 years ago and crumbled and cracked quite easily before it was covered by the tiles. Maybe it was laid too weak or too dry or maybe it was left uncovered for too long. Either way, it wasn't in brilliant condition when laid.
Now, on carefully taking up the tiles using a SDS hammer drill and tile lifting chisel, I find I am left with a floor in much better condition than I was expecting. The screed is bound together by a 5-8mm bed of hardened cement-based tile adhesive. What I would like to know is if it would be OK to leave this layer in place and use self-levelling compound over it to get a surface ready for the vinyl.
