. Hi, I am looking for some information on plaster patching to raggles, I have had the whole house rewired and the raggles to the plaster walls that take the cables are around 25mm deep. These have been patched by the plasterer and once dry the walls fully skim coated and the house has then been fully redecorated, now once finished the cable runs are very visable and I am getting told that over time they will disappear but I am not sure this is the case as some look slightly proud of the wall and some look slightly under the surface. Would appreciate any advice/ comments please.
