I have an external corner and plasterer has put in standard 3mm angle bead, one wall is plastered which is fine however the other side is being tiled and so the angle bead protrudes out. I’m having chrome trim put on the edge of tiles and this will in theory sit on top of the angle bead. So would you have the existing angle bead ripped out and the now skimmed wall patched back or would when tiling a thicker bed of cement used under the tiles to level it with the raised edge of the angle bead. I’m guessing it should have been stop bead used? Plasterer said it’s what he normally uses and not had any issues.
