Hi ptrott
Use cornice cement, mix a portion with table salt to increase setting time. The more salt the quicker it will harden. You may be able to multi coat with one mix. Have done this repair hundreds of times without problems.
Good Luck!
I am filling in the old square vents in the corners of the ceiling. I have done a few with plaster, but it is not the best. It takes ages to dry, and has to have 3 or 4 more applications before all shrinkage is filled in.
There has to be something better, Spakfilla??? Cornice cement?? What have you used successfully for thick filling in plaster?

i did your whole house a couple of months ago and used spakfilla as the bulk fill in 2 layers
then a coat of base filler followed by a skim coat and you cant tell they were ever there
but as we are renovating the house before we move in i wasnt in a rush
i let it dry a week between coats as im only able to work on the house on weekends
Cut them out with small grinder. Put in backing piece of board. cut square to suit hole glue and flush.

Thanks guys. I'll get on with it with some confidence now.
Cheers.
Or forget about the backing board, and just leave a couple of inches of paper, hanging out around the perimeter of the plug. Put cornice cement around the hole first to set the paper to. In a ceiling the plug may sag before it's set if it's is too heavy, but a small vent plug, cut tight to fit, should be OK.![]()
Way too hard pawnhead,
Master Plasterer hit the nail on the head
Quick and easy if you want to get rid of the vent altogether.
You don't like my easy-tape either, but there's only one small crack in my place (some of it was done 15 years ago), and I would have got that with paper tape as well I'm sure. I should have installed the plasterboard properly (running the sheet over the top of the doorway, instead of stopping on each side, and putting a piece over the top), but I was trying to save a bit on plasterboard. Nothing that a bit of paint won't fill anyway.![]()
Who mentioned easy-tape. I'll be having nightmares for months!!!
