I'm laying 9mm ply throughout prior to laying the engineered wood flooring, however where a fireplace used to be there is a 1400x730 concrete section that i have to cover.
I can't easily screw into this, so can I cover it with a sheet of ply, screwing into the floor boards where I can and then glueing it to the concrete using some mega grip - or other really strong gripping stuff?
