Hi all,

I have a dip of around 10mm in the corner of the room. I have wpd ply floor and have purchased some underfloor heating insulation but do I lay some slc to level the floor or build it up with tile adesive when I tile?

If slc what the best ?


So just to recap-
concrete floor with glued ply on top
then I want the u/f insulation
then tiles.

What should I do??

If i were you m8 i'd rip up the ply, level the floor, fit your insulation boards then level again (just up to height of cables) then you have a good surface to work to. Why was there ply glued to the concrete base?

Cannot take the floor up fitted kitchen in. It was put down as I was told I could use wbp ply for flooring then prime them u/f/h then tile. It's glued down with everything. Taking it up is not a opion
