Hello,

We have demolished a wall in an apartment built in 1947. Now we have a large hole along the entire ceiling from the previous wall that we need to patch up, and we're considering what might be best. Perhaps someone here has experience.

The ceiling consists of a microlite wallpaper/mesh wallpaper, then plaster mixed with reed and wire which is very porous. Under the plaster is a tight plank ceiling. (See pictures).

Since we want to avoid lowering the ceiling, our last resort is to frame the ceiling, so we've been considering a few other options:

1. Screw drywall directly onto the plaster, but we wonder if there's any risk due to the plaster.

2. Glue drywall directly onto the plaster with
a. Ardex S48 without screws, or,
b. Green Glue with screws

Which method have you chosen, given that you want to lose as little ceiling height as possible? Maybe there are other solutions?

Grateful for any answers!
 
  • A large opening in a ceiling showing exposed wooden beams and wiring, where a wall was removed in an apartment built in 1947.
  • A hole in a plaster ceiling reveals wood and straw lath structure beneath, with chipped plaster along edges.
  • A large ceiling gap in an old apartment, showing exposed porous plaster and lath after wall removal, with a visible wooden plank ceiling underneath.
Hey! I was wondering what you did in this case?
