The customer contacted me after a section of their cornice had fallen down, a cornice runs between the ceiling angle and the wall, the section that is on the ceiling is referred to as the projection
The customer told us that they had just had the room decorated and could we do the repair without damaging the wall paper, so we sheeted it from the bottom of the wall section of the cornice to the carpet to protect
Then we strips off the plaster from the lath and plaster ceiling, and gave the laths a very good clean removing all dust and any bits of plaster, to ensure we managed to get a good key to the laths
The next step was to start floating the ceiling paying particular attention to getting the ceiling as flat and level as possible, (when running in-situ it is very important that you are running off a smooth and flat surface)
We managed to safe a bit of the existing ceiling projection and made a zinc template
We decided to use a twin slipper running mould as this would give the running mould stability when running in-situ
We then run a length of mould on a bench to ensure that the template was an exact match to the original projection of the cornice
Next we waxed the running rules , then fixed them to the ceiling ensuring it would line up with the existing ceiling cornice
Once the rules were fixed it was then time to run the mould and worked on the section that would marry into the existing mould , and the mitres.
Once the mould was finished we skimmed the ceiling and removed the sheeting , another happy customer their cornice had been repaired without any damage to the wallpaper
