I have taken all the plaster off a bathroom and after cleaning want to leave it that way.
But there are huge gaps between the wall and the plasterboard ceiling with buckets of dust and rubbish piling down from the roof gap above. There is nothing between the wall and the nearest joist about 3" (7.5cm) away under the board with what seems like a waterproof sheet about 6 " (15cm) above.
I will be putting up plywood sheets over the plaster board as a ceiling but need to stop the dust falling through on to the back of it and through the gap between the plasterboard and wall when finished.
Foam filler was one idea but the gap is too wide and there is nothing for it to stick to while setting. I might be able to glue strips of wood to the joist to fill out the gap but no room to nail or screw anything either.
I know it will be impossible to get a clean finish beween the brick wall wall and ceiling but am not sure how to finish it either. Any suggestions and advice would be welcome.
