I am trying to work out the best way to install T&G solid oak flooring over an uneven kitchen floor.
The kitchen was extended by the previous occupants. The original part is flat and level (6ftx5ft), the newer part (10ftx6ft) slopes off (but is flat) from where it meets the old part. The drop is about 2 inches over 10ft. I tiled over this about 6 years ago and have smoothed out the ridge somewhat, but the transition from level to slope still remains. I will be installing the new flooring so that it runs lengthways with the ridge so the joints will take some of the curve.
The guy in the "orange" floorshop recommended laying down 6mm ply first to try and smooth out the ridge, but I would like second opinion on this matter. Also, should I glue down the ply to the tiles or screw? In addition, do I need any damp-proof membrane?
