Hi all, I'm intending to re-tile my kitchen floor. Existing tiles are laid on a screed floor. What is the best method for lifting the old floor tiles? I re-tiled my Utility Room floor a couple of months ago and lifted the old tiles with a good old hammer and chisel, but it took ages to chip off the adhesive and leave a smooth level floor for re-tiling. Was thinking of buying an SDS Drill with chisel action. Is this my best option, or any alternatives you can suggest? Many thanks in anticipation for the advice.
