some advice please anyone. starting a kitchen/utility/conservatory tomorrow with approx 50m2 of tiling. what i am concerned about is the floor consruction in the kitchen. at present there is karndean layed on 6mm ply but beneath that the original floor is a concrete sub floor with polystyrene insulation with chipboard on top. should i take the 6 mm ply up and replace with 12mm ply, the floor in the conservatory is concrete which also has karndean on it, thanks.
