I know this has been dealt with on previous occasions, but I wondered if there were any new perspectives.
I have removed tiles from my partition walls (plasterboard) of my kitchen, but am left with ridges of adhesive. I had thought of tiling over the adhesive, but it's likely that some I may be tiling both previously tiled areas and new areas, so there would be an uneven finish.
I have heard of various options including steam, heat guns etc. Which of these are suitable for plasterboard, and which tends to be the most effective?
