Hi there. So I've got a whole kitchen fitted with horribly ugly tiles and the walls are all plasterboard. I tried taking one out with a chisel only to cut into the wall a little. Was wondering what might be the best way to sort of save the wall, how I could safely remove the tiles + grout? And after removal, I wanted to plaster and paint (but I've never plastered before so I'm wondering if an easier option might be to flatten the surface by removing grout as much as possible and sort of add on new grout and tiles - if that's even something possible to do instead of plastering?) Thanks.
