I have removed a wall and it has left gaps in the cornice. Any ideas?
I have explored a corbel as an option and have chased up pressed metal options but I am after ideas.
I'm no plasterer and neither was my dad, but he was inventive, and did this…
Get some Plasticene [children's modelling clay] & press it up against a matching section of the cornice further over. Best if it goes on warmed slightly then left to cool, so it hardens a bit.
Lift away & then make a small wooden box frame for it.
Use plaster of paris or similar & pour into the mould.
When set, trim/file/sand to fit the gap & glue in place.
I roughed out a Photoshop copy/paste that shows it should match up pretty well - obviously was originally done in one piece. That should make matching up a whole lot easier. [Tinted pink so you can see what I added]
I would attempt to match the profile of the cornice. Even if you only come close it'll be much less conspicuous than a corbel at a seemingly random location.
